Jag V6 dyno results (at last)
40inches - 27/2/19 at 02:57 PM

Well 2.5 years after finishing the AJ30 install I have got round to getting it on a rolling road.
Two things that amaze me are:
How good this engine is and how close VEAL got the tune.

A power pull before adjustment saw 239bhp tuned solely with VEAL, however there is no substitute
for a rolling road tune, because you can't hit all the cells, and the ignition timing is not touched.
Before tuning on the RR the car was very good, but after the RR season it is superb
The BHP and Torque traces where a bit wiggly, to say the least, after RR tuning a complete contrast.
The Torque came in around 190/195ftlb from around 1500rpm up to 4000rpm, then climbed up
to 215lbft at 5600rpm before decaying.
The power peak was around 242bhp, flat between 6000rpm and 7200rpm and was still going
It will pull away from standstill in 5th with 2 up
If you are building an AJ30 install, you will not be disappointed, it was well worth the effort

Nice result


wylliezx9r - 27/2/19 at 05:31 PM

Nice. The car must go like stink. Do you know what the car weighs by any chance ?


Badger_McLetcher - 27/2/19 at 05:51 PM

Awesome! I can't wait to finish mine


big_wasa - 27/2/19 at 05:55 PM

That must be a great sound track.

I sort of wish I had gone with it instead of the turbo Zetec, maybe next time. I still look at and think that’s a lot of engine for a Locost

640kg without driver, but with 4 gallons of fuel. About 120kg up on the ZX9R

I used Kits and Classics in Chesterfield for the Dyno session, Jools the owner said he preferred the soundtrack of the V6 to a V8
He is a TVR specialist, so I was pleased with that comment


perksy - 27/2/19 at 10:05 PM

Thats a really good result

Peak Torque and BHP within 1500 rpm of each other, There ain't much wrong with that engine

Heard good things about Jools and his mapping


CosKev3 - 28/2/19 at 09:08 AM

Oh this is great to hear

Especially using the ST200 Inlet which looks more restrictive than the standard AJ30 one


CosKev3 - 28/2/19 at 09:10 AM

Did you experiment with the VVT?

Did the mapper say it's worth while/noticeable when the VVT is used?

The VVT was set to cut in at 5200rpm as on the S-Type, and yes you can see the blip on the graph, worth about
15bhp and 10 torques
I am going back, in about an hour, to have a play with the VVT. A power run with and without it fully activated, the logic being that there should be a cross over point that will become the switch point
The ST200 plenum and ST220 throttle body work well, still accelerating past the 7200RPM red line.
If you are running MS2 Extra I can email you the Msq file, when it is finalised?

Thats good to hear about the VVT

And yes please I would love a map that I know will allow me to fire up the engine thanks

Are you considering raising the rev limit as it's still pulling?


40inches - 28/2/19 at 04:31 PM

Well after an afternoon on the RR, it's all good news.
By moving switching points up and down the rev range Jools managed to get a conservative increase of
around 20bhp all the way from 2000rpm to 6200rpm with around 10bhp at the rev limit
Unfortunately the whole map was weak, so it will have to go back on the rollers for a remap.
So the gains with a remap should exceed 20bhp. That will be done in a few weeks time
I woder what the safe rev limit is? It sounds mega at 7000rpm as it is


CosKev3 - 28/2/19 at 05:30 PM

Nice one

So what revs was the best point for VVT?

I've read on line they can do 8000rpm happily due to the solid lifters.

How are you running the injection, batch fire or semi sequential?

The VVT was a bit of a head scratcher, and reverse intuative.
With no VVT the lower (2000rpm to 6000rpm) was the same, but the graph kept climbing up to the redline for
over 250bhp
With the VVT activated the lower showed a 10% (20-25)increase of torque and power but fell off at 6000rpm to 240bhp
but wouldn't idle
We figured out that the VVT was 2 stage and to combine the two graphs would need 2 programmable outputs from
the MS, and an extra relay i:e The VVT is off until 2000rpm, On until 6000rpm then back off!
So I am adding an extra relay to the VVT "control" box and then another full mapping season.
The injection is Semi sequential and ,surprisingly, Alpha N gave the best results..

Yea! From good to great


Ugg10 - 1/3/19 at 05:41 PM

The vct sound like it is similar to the Puma 1.7. Have search for Jenko on here. He found that it was best off up to about 2k then on until 6k and then off again above that. Without turning it off again he was loosing top end power. He also turn his off below about 30% load iirc. He used an onex600 ecu. The latest emerald k6 and me221 can do a fully mapped vct I think.

Ah right thanks

I've been recommended to wire the VVT solenoids in like injectors,so ignition live,then use a output channel on the MS to switch the earth to it?


40inches - 2/3/19 at 10:39 AM

That's right, I used the Fidle output, and now another spare output for the extra switch over.
Without activating the VVT the engine will still put out a lot of power low down, and will probably have an extra 15-20bhp
above 6000rpm (255-260) but, by activating it at 2000rpm and deactivating at 6000rpm that 15-20 bhp/torque will be
all the way from 2000rpm up to 7200rpm It's a no brainer.
We saw 254bhp, but with a weak mixture Once it's remapped?????????
I'll see if I can put up the initial graph.


40inches - 2/3/19 at 02:48 PM

This is the initial graph, you can see the bumps in the graphs when the VVT switches.
This is a very Torquey motor.

This is the graph with the power trace manually overlaid with 'OFF' VVT ,Red trace and
'ON' VVT Green trace. Just have to combine the two.

Ah right cheers

I'm struggling to understand the need for two outputs to control it though,surely one output can switch it on at 2000rpm then switch it off at 6000rpm?

Graph looks great

The programmable outputs on Megasquirt are only single action, If it is programmed to switch on, at say 6000rpm, that's it, until the revs drop bellow 6000rpm again. It isn't a deal breaker, I always use relays for the programmable outputs anyway, so it
is a simple job to put another relay alongside the original and cut into the VVT feed wire with the other relay.
I did that this afternoon
If you have yet to order your MS, get Phil to activate all the outputs ( costs £5 each) you can have dual maps for a fiver also

Mmm I'll have to ask Dale,as the output he suggested using was the one that controlled the boost solenoid when I had the turbo on the R1.
Pretty sure he said he could activate/deactivate that as he needed to to control the boost.

I've been running my MS since I charged the R1,just need to get Dale to add another driver for the extra two cylinders to run the AJ30.
He's recommended staying with batch fire injection too


theduck - 3/3/19 at 09:12 PM

Boost control is a pwm output and different to the “programmable” outputs.

Just got back from having the VVT set up.
272bhp after 2 hours on the dyno.
The photo upload has stopped working again So will post the Dyno graphs when I find
a suitable hosting site.


pigeondave - 24/3/19 at 01:50 PM

shiver me timbers
you must be happy with that.

How many torques.

Around 250 starting at over 200 at 2000rpm.
With the VVT set up as Jaguar from the factory, we got the rated 240bhp, it looks like
Jaguar neutered the engine, possibly for emissions????

I think on at 1800rpm with 60% TPS and off at 5800RPM.
Strangely the Jag setting is on at 5200rpm, according to one of the Jag manuals, and that
gives 240bhp as per the specs.
The engine had been mapped at the standard settings, but needed a lot more fuel added at the optimum settings.

Really good to know that the ST200 inlet hasn't restricted the engine!

How much more fuel could the standard injectors put in?

I've bought a set of 6 hole mustang injectors for mine,picked them up for what it would cost to get the originals refurbed so thought give them a go.

Not sure, will have a look at the settings, I think they are on about 85% duty cycle. They are around 240cc/min

That is seriously impressive output for an off the shelf engine, especially one normally used to lug an executive car up and down motorways. 90bhp/L without anything more than an engine map!

The problem is this is making me excited to get mine built, but I'm doing the kit car thing in reverse. Currently dismantling my second donor, so starting off with a car and ending up with a kit.

Only just, I had to fit a SAAB idler pulley to clear the chassis. There is 20mm clearance at the cam covers.
Doing it again I would fit an electric water pump, so no need for idler pulleys.

Yeah I've gone for EWP,never used one before but like the sound of how the controller works,faster warm up from cold is a bonus,the controller just pulses the pump at set intervals until the coolant is nearly at your target temperature set in controller.
With these engines having a remote thermostat the EWP set up makes the pipework set up much easier and neater too.


CosKev3 - 17/4/19 at 05:13 PM

Incase anybody comes across this thread in future and is interested in the weight of the engine heres some idea:

Bare engine with just small Denso alt fitted=120kg.

As above with ST200 upper inlet manifold and ST200 solid flywheel =132kg.

As above with RX8 6 speed gearbox and Mondeo 240mm clutch=181kg.

big_wasa - 17/4/19 at 05:49 PM

On the St220 the water pump is driven from a pulley on the back of the head and is prety compact. But that means more plumbing like a Zetec.

I did test fit the adapter plate last week end. One of the locating dowls is in a differant place.

I hope to get started on the wiring loom Easter Monday as the wife is working

I didn't take a pic of the graph,and Dale's printer wasn't working!

If Dale sees this he has it saved on the PC

Pretty sure the graph was still climbing at the 7100rpm limiter.

I did mention to Dale I had read of people running them to over 8000rpm,but he wasn't keen!!!!

That’s a great result.

Any chance of some engine bay shots now the photo uploader is working ?

I would love to see what this engine could make with some long primary headers and throttle bodies. I just don't know how you would get them in a 7.

Dale's currently mapping a Lambo that was in the Fast and Furious 8 that is running a AJ30 in it now,that's got some long primary manifolds on it as it has plenty of space in the back of a Lambo!
It's also running cams and some high comp pistons,but still on the standard AJ30 inlet manifold.

The steering column is the biggest issue in a seven type car to make a decent manifold fit on drivers side.

Throttle bodies would require a massive bonnet bulge,or a big cut out with a massive filter sat outside the bonnet.

big_wasa - 11/6/19 at 04:37 PM

You have to re size them first.

I already have the exhaust manifolds but there going to be more suited to a Gt style car.


sdh2903 - 11/6/19 at 04:45 PM

Rocketeer have ran jenveys and their own inlets on the dyno and the jenveys were down on power. I reckon I could fit itbs under my scoop but after seeing the results on a standard engine I'm not sure it's worth it. After seeing Dave's and kevs results on the st200 manifold I'm kind of a bit annoyed I didn't go that route. I always thought it just looked a bit restrictive obviously not!


RWD Focus - 11/6/19 at 04:53 PM

Ive got a couple of st200 manifolds but mine needs the throttle body at the front as the rear is too close to my bulkhead in my focus, i did consider chopping one up and moving throttle body to other end.


big_wasa - 11/6/19 at 05:30 PM

The Rocketeer tbs where on very short inlets with sock filters that are well known to rob power.

I am surprised how the st200 mani performs. Given the restrictions here and the exhaust 300bhp can’t be far off.

I guess the question I really want to know is what it drives and handles like ?

You maybe interested in selling one?

If using the st200 setup do you need both upper and lower manifolds? Or do you mate the upper to the jag lower?


RWD Focus - 11/6/19 at 06:46 PM

You mate the two together if i remember correctly. A member on here showed me how he had done his. Im gonna hang onto them just for now incase i need to cut more than one up to make it suit my application. There was one on eBay i think.


RWD Focus - 11/6/19 at 06:53 PM

Ignore that last message, ive just had a look in my other unit and found another st200 inlet complete. So if you want one give me a shout. Its upper with throttle body, lower, injectors and fuel rail. Can post if need be.

I've used plastic AJ30 lower inlet manifold,then chopped up a ST220 alloy lower inlet manifold to make up the 15mm spacer required to fill the gap between the AJ30 lower inlet and the ST200 upper inlet.
Had to weld some tabs onto the sides of the spacer and drill and tap them for the ST200 upper mounting points.


Partofthechaos - 11/6/19 at 09:56 PM

How do you sort the oval jag lower manifold ports and the round st200 upper?


CosKev3 - 12/6/19 at 05:05 AM

I've port matched them the best I could with a die grinder.

The ST200 twin round ports are bigger than the oval ST220/AJ30 ports,so I've ground out the alloy adapter plate I made out of the ST220 lower manifold to match the ST200 upper inlet.
Also took some material out of the ST200 upper between the round ports to make it into virtually one port.

If anyone wants pics U2U your email address and I'll happily send some,I cant be arsed re-sizing pics to add them to this old out of date forum!

Just turn the manifold round? you have to make a spacer anyway.


RWD Focus - 12/6/19 at 10:32 AM

Are they reversible? Would the majority of the bolts line up ?

The outlets are mirror images, so should be reversible. Non of the bolt hoes line up, hence the need for a adaptor/spacer.


RWD Focus - 12/6/19 at 10:55 AM

Just offered it up reversed but it catches on oil filler. In order to get it to clear it would be too high and catch on my wiper motor and linkage. Looks like I’m stuck with the one I made using jag inlet.
Thank you for your help and advice


40inches - 12/6/19 at 11:03 AM

Hope you don't mind me putting up your photos Kev?
This is how Kev did it, in my opinion the best way. It's much lower than mine, but needs a small amount of welding, i did mine
without resorting to machining or welding, but would do it Kevs way in hindsight

Can you cut away the idle control castings and weld on a blanking plate? Worth a try, you don't have anything to lose
I run mine without the idle valve, starts fine with a little throttle.


RWD Focus - 12/6/19 at 11:16 AM

Worth a look yes. Thanks

The reason for not using the full lower St220 on the Aj is it because the bolts don’t line up or the injectors are in a slightly different place ?

Edit st220 not st200

ST200 wouldn't fit into the V between heads,and ST220 lower the injectors are on a different angle,so dont point into port correctly,you could perhaps make it work by reshaping the inlet ports on the head,but obvs that's a head off job.

The lower manifolds are different between the ST200 and ST220/AJ30, I think in both ways
Must learn to type quicker

[Edited on 13-6-19 by 40inches]


big_wasa - 13/6/19 at 03:21 PM

Mines an ST220.

Would be nice if it stopped bloody raining so I could drag it out. I need to sort some engine mounts.


40inches - 13/6/19 at 03:21 PM

Just dug up my research on the AJ30 from 6 years ago
I found one fitted to a Robin Hood that had the standard Jag exhaust manifolds
and a ST220 inlet and Emerald ECU. It made less than the standard power, about 220bhp I think.
Another was fitted in a Westfield, this is the spec from his website:

"Jenvey inlet manifolds and 45mm throttle bodies
Simpson race exhausts stainless 3 2 1 merge collectors
Raceco 7 1/4" titanium re-packable silencers"

That must have been eye wateringly expensive for:
Maximum bhp: 270bhp @ 7050rpm
Maximum torque: 222lbft @ 5322rpm

I think we accidentally hit on the perfect combination with the ST200


big_wasa - 13/6/19 at 04:10 PM

I can’t get my head around that.

In the back of my mind I recall all the st200 / st24 owners wanting the American Svt manifold.

Is there a difference between st200 and the vanilla 2.5 Mondeo/ Cougar inlet ?


big_wasa - 13/6/19 at 04:14 PM

Funny enough the Rocketeer on carbon plenums with exhausts didn’t make the numbers either.

sdh2903 - 13/6/19 at 06:03 PM

The st200 inlet is different (I'm assuming bigger bore) as it used to be the upgrade of choice along with the throttle body on the st24.

The ST200 has the throttle valves in the lower manifold, and I think has the same throttle body opening as the ST220 (the ST220 throttle body fits straight on the ST200 manifold)
The runner bore is slightly larger as well, but the casting is the same, so easy to open them up with a burr grinder. You have to do that to match with the AJ30 lower anyway.

Taking the MX5 apart currently, Jag already broken. I hope to order the first part of the kit in the next month or so, with assemply starting in late August.

I plan to use the Rocketeer adapter plate to use the MX5 gearbox, so a slight variation on the ones I've seen that are on the road, though not sure what the practical difference will be.

Damn it. Never mind, it will allow me to get the engine in the car etc, and it may be useful to reduce the power until I'm used to it. Never driven a se7ven before, so in at the deep end... Once it arives I'll compaire it with the AJ30 lowers and report back.

I've used the rocketeer adapter, sump and flywheel in my Westfield I'm currently building. It's all good kit. Very well made.

How long did you have to wait for the rocketeer sump? Im fed up of emailing them asking when they will have some in stock again. Last i heard from them they said end of may, but now they won't even reply to my emails.

That's good to hear, most people say the quality is very good, but useful to hear it from someone on here.

Where does the recess in the Rocketeer sump end up? I was thinking of using the gap in the AJ30 sump as the route for an exhaust balance pipe, seems like the easiest location. But the Rocketeer sump would probably not need bits chopped offor baffles, so if the shape is right this would be easier.

Tighter to engine than the Jag one


RWD Focus - 14/6/19 at 05:12 PM

I’ve fabricated one using the ST220 inlet tracts and made my own plenum with flange welded on for the throttle body. I’m using an Impreza throttle body. It fits nice and snug to rocker cover and fits under my wiper linkage. My engine is mounted as far back as it can be without touching the bulkhead

After yet another day of frustration, I'm finally giving up on my ITB set up - there's just too many problems and it's too fragile (due to my inexperience with such systems and learning as I go); also the results you guys are getting from the ST200 inlet are awesome!

As I can't really be bothered to start an ITB setup from scratch again at this point; can someone tell me what the dimensions of the ST200 manifold are? Especially how far back the throttle body sits, as my coolant bottle is slap bang in the middle of my bulkhead!

Cheers,
Ben

I think you will have plenty of room for the coolant bottle Ben, the manifold isn't really that big, you can get to the spark plugs easily.
If you need any specific dimensions I can pop up to the garage?

Awesome, looks like it'll fit with some minor relocation of stuff; thanks for the info! The inlet and mapping are basically the only thing holding up getting the car finished at the moment, so hopefully using the ST200 inlet will let me get it running soon


RWD Focus - 16/6/19 at 01:43 PM

Not sure if any of you have any luck dealing with Bruce at Rocketeer but heres my experience of trying to buy a sump and gated baffle kit from him for the AJ30 engine.

Original enquiry by phone in early April, and he told me to email my enquiry him. This i did mid April and was told sumps available end of May. I then by reply sent him my full name, address, phone number and offered to pay in full up front for a sump. No reply to that email. In early June i emailed and asked if he had any update on the availability of sumps. again no reply. This morning i emailed him asking if he had any update and also asked if he was receiving my emails as he didn't seem to reply very often. His reply has just landed and it says the following:

Richard.
The sumps we have in stock are earmarked for kits. It'll be another couple of months before we have any surplus.

Best regards

Bruce

I understand a kit sale will make him more money than a sump sale but why not make it clear the sumps in production were for kits and not individual sale. The word tosser springs to mind, im pretty sure if i dealt with my customers in this way in either of my businesses i would have some very unhappy customers.
Rant over.
On with sump making tomorrow that will be ok for rallying rather than the one i made just to get a run out of the car as i was fully intent on using a proven one from Rocketeer.

Why not use the X-Type sump and pick up?


RWD Focus - 16/6/19 at 02:12 PM

It hits my crossmember, Its an xtype one i have altered to get a run out of the car.
I will just baffle it properly and use that one with slight changes to my crossmember.


Update on Rocketeers customer service skills. My latest email below and then his reply.

Bruce
Why didn’t you say that in April when i first emailed you, this was after phoning to enquire about a sump and being told to email my enquiry.
You then sent the following email on 26th April
"Richard,
New sumps should be in at the end of May.
Price is £350 including fitting kit and baffle.
A gated baffle is available if you're thinking of track work. Price £75
Bruce”

I then offered to pay for one and sent you my full name and address to which i received no reply.

Now you tell me no sumps available. Brilliant customer service skills i must say.
I will ensure as many people as possible get to know how you look after potential customers.


His reply has just arrived.

Richard.
I am looking after customers who have bought full kits. I'm sorry if that is inconvenient for you.
I'm grateful for the condor in your reply. Given your reaction I'll not be supplying you any parts at any time at any price.

Good day.


Im impressed by his response
What a legend.

Tig welder out tomorrow and Bruce can stick his sump up his hole, what a wanker.

The VVT was set to cut in at 5200rpm as on the S-Type, and yes you can see the blip on the graph, worth about
15bhp and 10 torques
I am going back, in about an hour, to have a play with the VVT. A power run with and without it fully activated, the logic being that there should be a cross over point that will become the switch point
The ST200 plenum and ST220 throttle body work well, still accelerating past the 7200RPM red line.
If you are running MS2 Extra I can email you the Msq file, when it is finalised?

I've measured the standard (?) 2.5L Ford V6 manifold. The inlet is 57mm, the ports onto the lower manifold are 27mm (long) and 30mm (short). Is anyone able to tell me how far away from the ST200 manifold is this please? Externally it is a very similar design as far as I can tell.

Right, I got me an ST24 inlet manifold to be getting on with, an ST220 throttle body and some 15mm aluminium plate to make some spacers out of. I offered up the Jag fuel rail but it's too tall - I'd need to make the spacer about 20mm. What fuel rails are you guys using? The ST220 and ST200 ones both look a bit lower profile.

Cheers,
Ben


CosKev3 - 22/6/19 at 05:30 PM

Standard AJ30 fuel rail on mine,with all the standard crap cut off the ends and AN6 fittings welded on.

ST220 injectors are at a different angle to AJ30,hence why a ST220 lower inlet wont fit.

What makes you say AJ30 rail wont fit?

What year engines did the plastic ones come off?

Both engines I've got had metal ones,strange


CosKev3 - 22/6/19 at 10:53 PM

Oh yeah just looked on ebay,the plastic fuel rail lower inlet is quite different to the one with a metal fuel rail.

I think you will need to get one with a metal rail to work with the ST200 upper.

On the top of the metal rail I've cut the pipe inlet off flat with the rail,then welded AN fittings on the ends.
On the rear of the rail under the TB I've had to extend the rail with some steel pipe and angle it down so the rail exits under the TB.

Mine is the plastic lower, but I used the 2litre fuel rail because it's dead ended.

Mines got plastic lower manifold,but not plastic fuel rail

Also the gasket set up/seals are different looking at pics,mine with the steel fuel rail uses oval O rings to seal to head and also the upper,the plastic fuel rail set up uses gaskets by the looks of it.


sdh2903 - 23/6/19 at 08:57 AM

This is what I have.

Seems to be the early engines had this set up then 01 onwards have the steel rail. This uses gaskets rather than the oval o rings.

Dave was yours the same as this? And you used the 2.0 v6 one? A straight swap I take it with injector fitment/angles etc?


sdh2903 - 23/6/19 at 09:17 AM

In fact looking on the bigger screen on the laptop looks like its going to have to be a full lower manifold change. Ffs. Hope the injectors are all the same as I've had these overhauled.

sdh2903 - 23/6/19 at 10:24 AM

Cheers Dave. I dont know if its camera angles or if the lower manifold with the steel rail looks thinner? than the one with the plastic rail aswell.


40inches - 23/6/19 at 11:29 AM

The steel rail is thinner and much lower profile.


sdh2903 - 23/6/19 at 11:30 AM

Have just offered up the inlet (with fuel rail removed) and I'm still probably a 25mm spacer short.

Having seen the pics of kevs build up his lower inlet looks a bit thicker. Have measured up the lower inlet and I have a depth of around 47mm. If anyone has the type of lower manifold with the metal fuel rail could you by any chance measure its thickness to compare?

I was meaning the lower manifold itself Dave. Sorry it wasnt very clear.


40inches - 23/6/19 at 12:03 PM

I have just measured my spacer and it is 30mm, that gives me 30mm clearance to the highest part of the steel fuel rail
from the manifold. So a 15mm spacer would give 15mm clearance.
I will see if I can measure the lower inlet. my engine is a 2001.


40inches - 23/6/19 at 12:15 PM

As near as I can tell the lower manifold is 50mm high.

I've just sussed that another reason why its sat a bit higher is of the COP's its resting on them. A 25mm spacer will do I think. Think I'm going to have to go the same road as kev and machine an st220 manifold to suit as I dont fancy drilling out a 25mm block of ally

I went for a coil pack instead of COP.
The upper/lower ST200 seal is a plastic/rubber gasket about 4/5mm thick. I don't see why a couple can't be stacked

If anyone interested here is the difference between the 2 lower inlets. The all plastic fuel rail version is 99-01 and the steel rail is 01 onwards. There is a 10mm difference in height with the steel rail version being taller aswell as the much taller fuel rail with the plastic rail.

The 2.1 rail works a treat with no blanking of the fuel rail pressure sensor needed. Thanks for the heads up with that Dave.

I finally got around to slapping the plenum on the Duratec 30. The ports are huge and look much bigger than the St200.

Question, how high does the st200 manifold sit above the rocker cover please ?

I will try and get some better photos if it compares well.



I also commented that the Aj30 plate didn’t bolt direct to the Duratec 30 as there was a dowl in a differant location. I got the dowl out but the plate doesn’t seem a great fit. Even with just one dowl in the block I can’t get all the bolts to go in. And I can tell from the starter flywheel it’s not 100% centred.

RWD Focus - 22/7/19 at 06:15 PM

On the Jaguar version there are two senders close to each other on the near side of the engine tapped into an oil gallery. One has one wire one has two wires. Am I right in thinking the one with one wire is oil light and the other one is oil temperature? Or is it an oil pressure sender ? Thanks


big_wasa - 22/7/19 at 06:34 PM

One wire is the low oil pressure switch. It earths through the block. The second ? Wouldn’t oil temp need more volume like in the sump ?


RWD Focus - 22/7/19 at 06:52 PM

I thought 1 wire would be for oil pressure light. Maybe the car had an oil pressure gauge, i can't remember, that may be the 2 wire sender. Your right about oil temp probably needing to be in the sump.
I will get a couple of pics tomorrow.

If you unscrew the sender it will be clear to see if its temp or pressure.
Temp will be solid,pressure will have a hole in the end!

Wonder how they mounted that engine?

Never seen a filter set up like that,or is that a FWD engine?

Only had my hands on RWD s-type ones


RWD Focus - 22/7/19 at 07:46 PM

Strange isn't it. I would say FWD. Mine is mounted very differently. Ive fabricated mounts to pick up on the bolt holes around the oil switches, and same area on the other side

[Edited on 22/7/19 by RWD Focus]


40inches - 22/7/19 at 09:57 PM

Looks like a Ford FWD, possibly a X-type. That photo is the front view.
When they converted it to RWD they used the oil filter/cooler as the engine mount you find on the S-Type.

Yeh that looks like an x type lump. There is a huge lump of cast iron in the V to hang it of the inner wing. It’s so big you have to take a head of to get it out.


big_wasa - 23/7/19 at 04:31 PM

So I am pondering now.

I’ve seen an st220 converted to Awd with the jag x type box so they must be the same bolt drilling’s.


andygtt - 10/10/19 at 10:14 AM

The block for the 3.0L S type / X type and ST220 are the same so all the boxes bolt up if you move the dowels.

Crank is also the the same as is oil pump etc.

Ive swopped between blocks from each in my car when Ive done rebuilds.


Incidentally has anyone considered the plastic plenum from the Maverick... as used on nobles to over 700bhp (mine being one of them).
Looking at the Rocketeer carbon manifold, it looks loverly, but for a single throttle NA engine the chambers look too large to me... given the results being poorer than the ST200 manifold I wonder if they got it wrong.
Ive developed ITB's for mine... it outperforms the ST220 manifold above 6500rpm considerably.

big_wasa - 10/10/19 at 10:57 AM

Ive been looking at plenum options. Including the 3.7L Cobra.
Trouble with itb's for a 7 style car is going to be height. The fwd manifold actually sits nicely in a 7 due to the step in the bulkhead.

Ive got a lovely set of Nasp exhaust manifolds designed for 3.5/3.7. Not that they would be any good in a 7.

I would love to find a set of -1mm rods like the Nobel. Yours is definitely something to aspire to.


andygtt - 10/10/19 at 11:10 AM

actually -2mm

I actually have 5 spare... as I seem to have lost the 6th one lol

you can get forged pistons that suit the stock length rod (which I run) and you can get KI stock length rods for $600.... but it starts to add up when you find you need oil squirters machined into the stock block and the gaskets and stretch bolts are not cheap...

Not cheap... but then what engine is when your tuning it 3-4 times its stock power?

Interesting single twin scroll turbo by the looks of it, which one if you don't mind me asking??, and what sort of power band/bhp are you looking at? (i'll be building a new turbo engine for my Metro over the next few months and i'm just gathering info/options...and parts lol).

Ian


andygtt - 10/10/19 at 01:14 PM

I used to run a BW S300SX, made over 700bhp easy and my intake was the limitation... it WAS NOT laggy before anyone asks, it way outperformed any previous twin turbo setup I previously ran.

This engine made power from 4000-8000rpm... it made 700bhp for 1500rpm so wasn't peaky.
It was making 500ftlb from 4000rpm! peak torque was 630ftlb wish from memory.

For the Jag heads and the new engine package Im targeting 8500rpm and much more power than before.

For the new spec engine I have moved to a BW EFR9174 which I have seen make 1000bhp... but you really need to match the compressor map to your engine.

Yes thats one of my old dyno charts, I moved it on 50bhp from that a few years later

had the same throttle response to my V10 M5's so it was very controllable on the throttle.... This V6 is a truly awesome bit of kit and very underrated and underused.

Worth mentioning the ford version of the sump has the bowl and pickup at the rear so might well miss a 7 type crossmember!

Very nice

Is that a mondeo gearbox?

What clutch do you use for that power?


andygtt - 11/10/19 at 06:03 AM

I used to run a ford mondeo ST220 gearbox (that's what's fitted stock in the noble)... but Ive made an adapter plate and moved to a more modern box with beefier internals so I can release more torque (it was capped at around 630ftlb in the mod range). Not run the new box yet.

I developed a triple plate clutch to fit the engine, very light and responsive... so light it allows flat shifts going up (similar shift times to a sequential) but has to be heavily blipped going down as it drops to idle between shifts if you change normally. kinda tainted the driving experience on the road but I wasn't prepared to take a backwards step so am going DBW to control the down shifts and retain the awesome upshifts.

Its not a dyno queen engine either, totally usable the car does 0-150mph in sub 10 seconds... that's with no traction aids, which shows the spread of power and contrail nature of the engine.

I love this engine which is why i'm continuing to tweek it and find the best places to make more power for less boost.


RWD Focus - 11/10/19 at 06:45 AM

Hi Andy
You say you have developed a throttle body set up. What actual throttle bodies are you using?
Thank you
Richard


andygtt - 11/10/19 at 08:22 AM

M3 throttle bodies with a carbon lower manifold to adapt from the ITB's to the head.

Nice

Must agree on the power delivery,from the moment you touch the throttle to the rev limiter it's so linear, no torque spikes etc.

You've made the carbon parts yourself for ITBs?

Pics would be great please


andygtt - 11/10/19 at 09:03 AM

there is a picture above of the carbon plenum I made... my whole car is carbon, just making a new dash ATM.

Really must stop playing with the noble and get back to the carbon capri... Im easily distracted with my hobby projects lol

I must admit i'm really looking forward to playing with the VVT on the jag heads, the ford ones were on the absolute limit at 8000rpm (due to the rockers but I never actually had a failure despite going to 8100rpm), I've gone dry sump so I can go higher with the jag ones (oil pump is the limitation on revs on the Jag BTW) but i'm not sure if the VVT is going to cope at those rev ranges.

The fact the stock engine with a decent intake and exhaust can go to 270-280bhp bodes well compared to the Ford heads that can't get close to that.

I get excited by threads like this by people bucking the trend and trying there own ideas... so many armchair experts when it comes to these areas its hard to sift the facts from the bull.


CosKev3 - 11/10/19 at 09:23 AM

The VVT restricted top end power on mine,so now it comes on at 1800rpm and goes off at 5800rpm,rev limit set to 7100rpm and power was still climbing but mapper wasn't too keen to rev it higher!

My m8 has deleted the VVT,runs Piper cams and a 8500rpm rev limiter,running a dry sump system along with forged rods and pistons and Jenvey Itbs,that made 326bhp.


andygtt - 11/10/19 at 09:49 AM

On stock pistons I wouldn't rev it too high either, I run forged pistons.

Main reason to run ITB's on mine is so I could make the plenum to whatever size I wanted, my stock ford one becomes less efficient above 6500rpm and can't flow enough air for much more than 700bhp... the gains Im expecting will be from that rather than the ITB's themselves.
As I said earlier, whilst good looking the Rocketeer plenum doesn't look the right volumes for NA to me, if its slightly wrong it will loose power all over the place... its this reason I went ITB, as the plenum size is less sensitive, its just about getting runner lengths correct on ITB's and they are relatively easy to get right.

On the dyno on a stock ST220 engine my ITB's gained power everywhere except between 4500-6500rpm... and I cap torque to save the box in that rev range..... now don't get me wrong the ITB's never bettered the stock plenum as the engines peak was in that range, but stock it goes off a total cliff at 6500rpm and my ITB's kept it climbing to 7100rpm were the engine hit its cam limit.
I expected the mid and top end results, but it was a total surprise to find they were better slightly low down, I was expecting it to be rubbish there.

Im also hoping to unleash some music from the engine, the turbo makes it loose the V6 song and just becomes angry sounding rather than tuneful if that makes sense.


Oddified - 11/10/19 at 09:54 AM

My goals are only 450/500bhp (at least for now lol). Plan is just fit k1 rods, forged pistons, drill for the oil squirters (but also fit jets, not just drilled holes...), mild porting/cleaning up in the heads and it should make what i'm after with less than 1 bar boost. Interesting that your running up to 8000rpm on the st220 heads/finger follows, standard valve springs or uprated?.

Stock noble engines with cast pistons and short rods make reliable 450-500bhp, add forged pistons and you can go to 550bhp.

What you plan should see your target at 0.6-7 bar... the ford heads respond fantastically to mild flowing (much better than the jag versions).... with my massive old truck turbo mine made 480bhp at 0.6bar and a very usable power band, I could give it full beans in wet with this actuator pressure it was so smooth.

DONT run stock valve springs, fit the piper upgraded ones, boost makes the valves bounce with stock springs even at low revs and in worst case can cause the valves to fail (ie head drop off), its rare, but it has happened.... its for this reason noble retarded the exhaust cam one tooth to reduce the engines top end rpm range.

The noble block just has welding tips drilled and tapped into the block, I've had the valve versions but am moving away from them as its another thing to fail without you being aware... I can monitor and manage idle oil pressure.

The oil pump is the mechanical limitation for revs as past 8000rpm it cavities and can also break, the followers are claimed to fail, but I've not know of them failing even though I've rev'd to that for 8 years and know of others who have taken them to 8600rpm (big issues for the ST220 engine at those revs tho).

The VVT was set to cut in at 5200rpm as on the S-Type, and yes you can see the blip on the graph, worth about
15bhp and 10 torques
I am going back, in about an hour, to have a play with the VVT. A power run with and without it fully activated, the logic being that there should be a cross over point that will become the switch point
The ST200 plenum and ST220 throttle body work well, still accelerating past the 7200RPM red line.
If you are running MS2 Extra I can email you the Msq file, when it is finalised?


Hi
Just been shown a diagram from Jag that shows the VVT being 'advanced' from 1000rpm to 5200rpm,and 'retarded' from 5200rpm to the red line.

With the lock down, i've been using the car for essential journeys/shopping, and perhaps a little bit of mapping/fine tuning along the way. Started with 0.6bar boost, then shortly after increasing that i needed larger injectors again and a stronger clutch and upped the wastegate spring, boost solenoid/closed loop, ecu knock detection/control, water/meth injection over 1 bar and data logging everything. The engines really do like a bit of boost! , 3 switchable maps set up now with 0.85bar, 1 bar and 1.25 bar...for now!. It does go very well indeed

Hi guys a bit of advice if I may.

I’m using the AJ30 with an RX8 gearbox in a Chrysler Sunbeam With some of the Rocketeer parts.

What exhaust manifolds are being used? I can find Moneo tubular ones but I can’t seem to find any RWD application ones that I can then modify?

I used a aftermarket mondeo one modified on the passenger side.

On the drivers side I've used a aftermarket Mitsubishi FTO one with a AJ30 flange welded onto it.

DanST engineering sell AJ30 manifold flanges.

I've run the drivers side under the sump,using a Jag xtype sump,then merged them together into one exhaust system on the pass side as I didn't want twin exhausts on the outside of my car.

If you want some pics email me teare820@btinternet.com

big_wasa - 3/5/20 at 07:36 AM

They are from a Ginetta G50 with the 3.5/3.7 cyclone engine.

I’ve chopped the flange of and bought some thick stainless steel Aj/Duratec30 flanges. I’ve only got as far as tacking one side on due to multi projects.

They will suit a Gt style car but probably not my 7.

If you have been lucky enough to be able to buy Rocketeer parts would they not sell you a pair of there’s ?


Nevtiger - 3/5/20 at 08:56 AM

Interesting you should say that!

I had asked Bruce for a pair of manifolds, he said they would be a few months but eventually he then sent out the email to all customers stating they were going to concentrate on converting cars only so I never did get a pair. However they would still need modifying as the starter is still in the Jaguar position and not the Rocketeer position.


big_wasa - 3/5/20 at 09:24 AM

One of the chaps on here had a similar run in with a Bruce but didn’t manage to get any parts. I think he then said he would only do the kits. Strange as the market for a kit must be small but people spending smaller chunks for there own projects will be larger. In my book a sale is a profit, so his must be more off a hobby for like minded mx5 fans with deep pockets.


DanSt does some nice head flanges.


Nevtiger - 3/5/20 at 09:44 AM

I didn’t have a run in with Bruce I found him to be a nice guy. Biggest issue for him I believe was he was/is? In full time employment as well as doing the kits.

But I do agree that sales to allow conversions to other vehicles would be a cash bonus for him.

I contacted Rocketeer before I started my conversion, but £1300 for sump/flywheel/bell housing to mount a £200 engine didn't feel right or make sense to me!

Circa £400 doing it the way I have with the adapter plate and modified ST200 flywheel.


big_wasa - 3/5/20 at 05:27 PM

I don’t mind paying for good quality parts but there is something very satisfying about macking stuff.


Nevtiger - 20/5/20 at 03:42 PM

Interestingly Rocketeer have started selling things again to self builders. They had put a stop on it.


big_wasa - 31/5/20 at 05:45 PM

Wow wow wow.

I’ve just watched Ian’s latest dyno vid and wow again 500 bhp plus. That is a very cool engine in a very cool car.

Can I ask where you sourced the pistons and rods please.

The engines do work well with a bit of boost!

I had a set of custom Wiseco pistons made, i wanted 9.5-1 comp and it was the easiest way (if not cheap..) to get exactly what i wanted.
The rods came from Xpower engines with ARP bolts, probably just Chinese rods like K1's and most others that are sub £100 each, look, feel and measured up spot on though.

The only other things i did to the engine are- under piston oil jets (i used BMW valved jets, drilled the block and pressed in), Piper valve springs/caps, mild porting in the heads/cut the seats/valves and Siemens 60lb/630cc injectors (they are maxed out at over 90% duty cycles on the high boost setting though).

It seems you don't have to try to hard to make over 500bhp with these engines...


Markymark - 1/6/20 at 08:33 AM

Hi, sorry to hijack the thread but Oddified what piston oil cooler jets did you use (part number?) as I could do with adding some in my engine, Alfa V6, having changed the rods these are now missing, the high output engines had them as standard in the block as well. If this is doable it would be a great solution. Some pics would be really useful. PM me if you don't want to derail this excellent thread.

Many Thanks in advance

That is exactly the spec I would have suggested for a reliable 500+bhp engine build :-)

I have a set of those XPower rods on the shelf, I also have arrow ones to compare against and I must admit for 1/3 of the cost they are much better than I expected. Can’t fault them at all.

As you know my ford head version made around 730bhp, and revd to 8000rpm with very little difference in spec to yours... I had mountune cams (ground by piper) and arrow rods.... I recommend ARP head bolts only as they are not much more expensive than the ford ones, yet better and more importantly reusable. Ford ones won’t be an issue tho and can hold 1.4bar.

I used to run the same injectors as you, I turned the fuel pressure up and was able to get a lot more fuel in that way... just an option for you when you want more power lol

The was checking piston to valve clearance with my jag heads and VVT last night, wanted to see how much lift I can go to with my all new setup.... quite excited to see how the Jag heads perform when boosted.... target is 1000bhp :-)


andygtt - 3/7/20 at 07:26 AM

BTW... my experience is EGT is the enemy with this engine when turbocharged, it’s worth monitoring and putting safeties in for it.


Oddified - 3/7/20 at 08:04 AM

I've turned the fuel pressure up a few weeks ago , 4 bar at idle now but i've also been tinkering with many other things as well, on maximum attack mode the injectors are touching 92% duty, afr's around 11.4 so not overly rich either for the boost/power.

I have the pre turbo/exhaust manifold pressure connected into the ecu and logged so i can see the pre/post turbo pressure ratio, that also gives some very good info on the general 'happiness' of the setup and turbo efficiency but an egt sensor connected into the ecu is probably also a good idea with some trims/compensations mapped in.

Along with many other things done to the car during the lockdown, i've just fitted an EGT gauge/sensor. What sort of temperatures are generally considered safe/a bit on the limit/risky??.


andygtt - 11/8/20 at 08:37 PM

well the material the valves are made of is rated to 850 deg c... i recorded 900 deg c on 0.6bar and 950 deg c on high boost.

So i upgraded to inconel valves

Oh!

Do you run multiple EGT probes in each header, if not where is the single one positioned?


andygtt - 12/8/20 at 06:12 AM

Im mine i ran one per bank in the noble collector which is about 6inches from the head... its not an idea reading but better than nothing.
Certainly its better than running one post turbo which is what all the others running EGT on the noble do.

Im currently upgrading the Motec ECU to something a bit more advanced and will monitor every bank.... its gets expensive very quickly as just getting the bung welded into the inconel manifolds is over £500, then i need the sensor etc etc


Oddified - 12/8/20 at 01:24 PM

Useful info as always

I fitted one sensor, it's on no2 cylinder about 4" from the head/exhaust flange. On my low boost setting (0.75 bar boost / 430bhp) the highest peak egt i've had is 792c and that was foot flat uphill.

I've not tried it yet on the higher boost settings as i'm trying to be kind to a new clutch and bed it it in a bit lol. Obviously i expect the EGT's to go up with the higher boost settings. Googling and reading various forums, 900c generally seems to be considered the maximum, above is a bit risky and get up to 950 - 1000c is very risky (all assuming regular exhaust valves of course).

The gauge is linked into the ecu and i've setup compensations to add fuel above 900c but i'll have to see yet where it ends up on maximum attack mode

Ian


andygtt - 12/8/20 at 02:03 PM

I suspect a lot of the heat is because of the noble collector design which seems restrictive plus im measuring 3 cylinders all in that very restriction.
Im remaking one of the manifolds to get rid of this restriction... can do nothing about the other as the turbo is there

I think your way is better for getting an accurate reading... I based my safeties off of it, so if one changed significantly from the other it would start cutting boost etc.

With a few more miles on the clutch, i checked the EGT's on map 2 today (1.25bar boost, ~500bhp) and peaked at 890c. Logically map 3 will create higher EGT's again but i have map 3 running a bit richer and it also activates the water/meth system (on maps 1 and 2 the water/meth isn't used) so time will tell when i check it, plus i only intend to run this setting for a bit of drag racing so it'll only be for a few seconds

Ian


andygtt - 21/8/20 at 08:09 AM

My EGT went from 900deg c on low boost 0.6bar to 950deg c on 1.45bar high boost.... it was around 470-480bhp on 0.6bar so not miles away from what your seeing at 500bhp so Im interested if you see the same increase trend I had when you push the power up.


sdh2903 - 4/10/20 at 07:32 PM

My build is now complete (well as complete as they ever get) big thanks to dave and kev for all their help along the way. Without seeing dave's build I prob never would have thought of using the Aj30.

Had the car back on the rollers a couple weeks back to iron out a couple of wrinkles and also the first visit my fuel pump was starting to fail. Gained a useful 20bhp and ended up with 229 bhp on a hub dyno.




big_wasa - 4/10/20 at 07:39 PM

Anything of the exhaust please And I though a turbo zetec was crammed in.


sdh2903 - 4/10/20 at 08:13 PM

I don't have many useful pics of the exhausts to be honest. I'm using the same st220 manifolds as dave. If I were chasing more power theres prob some decent gains to be had from a pair of tubular manifolds. I do fancy giving tig welding a bash at some point so may well revisit.




40inches - 5/10/20 at 08:58 AM

Good job Steve Another AJ30, we need to start a club
Kev has long exhaust manifold headers, his has around 10bhp more than mine.


big_wasa - 5/10/20 at 09:29 AM

Very nice, thank you.

I've got some veeeeery long primary headers. I can't see me getting them in a 7 though. Hence comparing other ideas.


40inches - 5/10/20 at 09:40 AM

What starter did you use Steve?
I had to use 25mm spacers for the downpipe to clear it.

I've had mine on three RRs now with massive differences in power,even though car is going as well as always!

Did 286 BHP when getting mapped, then at two RR days with different kit car clubs it did 232bhp,then the last time was 244bhp!

Although I've lowered the rev limiter to 6900rpm to try and stop me killing alternators and the power is still rising at 6900rpm on the rollers of the latest two runs so that will have reduced the top figure slightly.....


sdh2903 - 5/10/20 at 09:58 AM

I am using the rocketeer sump which tucks the standard s type starter right in so no issues with clearance.

Well after much messing about with clutches for several months, making my own twin plate which sorted that and then breaking 4th gear in the gearbox a few days afterwards which is now changed for the bigger/stronger 01E box...everything's holding together perfectly now! lol . Boost setting #3/maximum attack mode tested up to 2 bar boost, the peak egt's are only around 880c but on this setting i have it running richer at around 11.0 afr and also water/meth activated with a 10 gph nozzle (devils own system) which is no higher egt's than the lower boost setting (but that's a little leaner and no water/meth). The engine certainly likes a little bit more fuel and water/meth (which also helped lower the IAT's as expected) and the car is quite nippy at 2 bar boost!

2bar, very impressive!!!! i was 650hp at the hubs with 1.45bar, but i couldn't get the inlet to make more power with extra boost above that even though my turbo could deliver 2bar.

What inlet manifold are you running? did you machine your cams?.

Good to know the heads can take that kind of boost, In previous iterations I ran up to 1.6bar but it was actually less power (626bhp flywheel) at the time due to the engine spec i ran.... I capped at 1.6bar as at the time didn't know if the engine/transmission could take more than 600bhp (it was widely thought it couldn't at the time).

The inlet manifold is the st220, i ported the heads/intermediate/manifold, of course the main manifold isn't totally possible after about 6" in from either ends. The cams are std st220 (timed correctly). I don't think the intake manifold is particularly good but i also think the exhaust manifold is just as important and they are tubular and equal long length on every cylinder. I've had it briefly up to 2.5 bar but the logs suggest everything was maxed out/on the limit/over the hill...not to mention grip was a major issue! lol. Being realistic 2 - 2.2 bar is the max that's sustainable on my current setup.


mgb281 - 17/3/21 at 08:40 PM

If anyone is looking for a cheap 65mm throttle body the go to Ebay.com (USA) and search for a Ford Crown Victoria throttle body from the late nineties on a 4.6 litre V8. It has the same mounting hole distances. I paid less than £30 including postage from a 56000 mile car.


mgb281 - 19/3/21 at 09:05 PM

Costkev
What do you put the variation down to? two of you posted similar figures last year (or was it the year before) when the mapping was done. A 40bhp drop is quite a chunk, were the original figures a little ambitious or are there other factors, not finger pointing just curious.

I am building an engine for another TVR S (mine uses a home made intermediate ally block between the standard AJ30 lower inlet and injectors and home made runners fed from an Alfa plenum and 70mm FBW TB giving 265bhp)
This time after reading this thread, using the AJ30 lower and injectors, cut down ST220 inlet and a ST200 main plenum. I would like some advice on TB's as the standard ST200 is 65mm but cable operated and the standard AJ30 is 70mm FBW but also a monstrosity of a unit with its idle control. Will be using an Emerald K6+ ecu.
On my car Jools had problems getting a steady idle, it hunts between 900 and 1500 rpm when cold and a bit better when hot. He thinks the 70mm may be too large and difficult at small throttle openings.
Should I go 65 or 70 is the question.


40inches - 28/3/21 at 06:56 PM

I used the ST220 throttle body, can't remember the size but Joolz didn't find any a problem with idle.
Should say that I think the ST220 TB is around 68-70mm and is cable operated which gives a good amount of adjustment for idle.

The Crown Victoria/Mustang one is actually 67mm, its worth a look, you may need to look for a while due to most of the sellers charging silly prices to send to the UK. When I bought is was with Ebay's Global Shipping but here is an example;

I'm fairly sure the standard ST220 throttle body is 60mm (i'll double check tomorrow as i have one on my bench..). I have a 68mm fbw on now from a Merc, no issues what so ever but not really relevant as the engine isn't standard and a turbo fitted.


sdh2903 - 28/3/21 at 09:43 PM

Standard st200/st220 is 60mm. I had mine bored out to 65mm.

The only issues I've had with idle were air leak issues between the st200 inlet and the adapter plates. Thick Cork gaskets cured it. I don't run an Iacv and mine idles even from cold with no pedal input quite happily. Although to assist I did raise the idle to around 950/1000 rpms.

I found it to be hyper sensitive when trying to use an iacv, I tried the Ford and also a bosch one.


40inches - 29/3/21 at 08:09 AM

Yep, I was wrong. Checking my notes and memory the ST220 is 60mm and the TB that came with the ST200 inlet was 50mm
My set up with ST200 inlet and ST220 TB was still flowing and increasing power at 7200rpm


magpies - 29/3/21 at 09:53 AM

from the info above am I right in saying:

The ST200 plenum would have come with a 50mm TB but some have fitted a ST220 TB (60mm) or even a bored out one to 68mm with good results.

I presume the ST200 plenum inlet has been opened up and tapered from ,say, 60mm to the 50mm throat. Then a tapered make up piece to connect the 65/68/70mm TB to the ST200 plenum inlet?

Or has the ST200 inlet been opened up so the smallest dia is 60mm?


sdh2903 - 29/3/21 at 11:15 AM

The stock st200 TB is 60mm. The stock st220 TB is also 60mm.

The lesser 2.5 v6 is the one with the smaller body.

The inlet to the st200 plenum is around 65mm so that's why I had the body bored to match.

The st24 plenums have smaller diameter runners and inlet.

I presume the ST200 plenum inlet has been opened up and tapered from ,say, 60mm to the 50mm throat. Then a tapered make up piece to connect the 65/68/70mm TB to the ST200 plenum inlet?

Or has the ST200 inlet been opened up so the smallest dia is 60mm?


My ST200 plenum was fitted with a 50mm TB, but the inlet bore was 60mm!!! so the 60mm bolted straight on.
Just my personal opinion, but with my RR results, I can't see the point in fitting one larger than 60mm.


magpies - 29/3/21 at 11:38 AM

Just been down to the garage and measured the inlet. 65mm. Looks easy to open up to 70 to fit the Jag or vw Audi TB.


sdh2903 - 29/3/21 at 01:51 PM

Or you could try fitting 6 x 45mm ones instead

I'm trying it on a much much smaller budget


magpies - 29/3/21 at 04:40 PM

aiming for about 270bhp which seems to be middle of the road, but more importantly driveability as the car will be used for 'touring' and the wife will drive it too.
60 or 65mm throttle body being the choice of ST200.220.
These are cable operated .

I have a TVR with the Jag engine and a Fly By Wire
70mm Throttle Body - mapped by Joolz.
There is a bit of 'hunting' at tickover, Joolz again saying low power throttle response it better with the cable operated TB's. Also better with the smaller TBs

This engine will have to have Cats fitted as it is a 1993, so looking at Kraken 200 or even 100 cell units.

I have the opportunity to buy the Mondeo Fidanza flywheel for less than the cost of having my ST200 flywheel refaced, balanced and lightened, in fact if I sold the ST200 one I would be pounds in pocket. BUT will I have a problem with the starter engaging the flywheel from the wrong side? Is it a good or bad move?

Cheapest 65mm throttle body is this; https://www.ebay.com/itm/98-04-GRAND-MARQUIS-Throttle-Body/301834522457?hash=item4646bd4f59%3Ag%3A4oIAAOSwSHZWfujf&LH_ItemCondition=4
The seller is not stating postage but when I enquired about one (different seller) they sent it with Ebay's Global Shipping Program. I have now forgotten how much the total was but I have posted it somewhere on this forum. Standard Ford TPS plug as well

[Edited on 15/4/21 by mgb281]


Oddified - 15/4/21 at 08:06 PM

I believe there's two versions of Fidanza flywheel with differing back spacing and use different clutch cover and release bearing positions. Just something to look into/check out.


mgb281 - 15/4/21 at 08:21 PM

Its the Fidanza flywheel for 2.5 Mondeos, since we know the standard 2.5 Mondeo flywheel works this one should too. The only thing in my mind is the starter engaging from the wrong side but the ring gear sits on a shoulder which should prevent it moving, that assuming that it does.


big_wasa - 15/4/21 at 08:52 PM

What gearbox are you using ?


mgb281 - 15/4/21 at 09:05 PM

5 speed RX8, I am sure that we all know that the internet quotes that fifth gear is 0.82 when we in Europe got 0.76


big_wasa - 16/4/21 at 05:03 AM

If you are using Johnathan's adapter plate then NO the jag starter motor will not match the ford flywheel ring gear. The jag has a bigger dia and differant pitch.

Two options.
Modify the Ford flywheel to take the jag ring gear.
Or
Modify the starter motor and adapter very slightly.


mgb281 - 16/4/21 at 09:48 AM

I have already modified both Freddy’s adapter plate and the S type starter motor and they do fit. The question is all about the Fidanza flywheel which is the correct one for Mondeo so the same dimensions as the ST24/200. I cannot remember which is the lighter one but that’s what I have. My build is the standard one that most of you are following; 2002 S Type engine, Freddy’s adapter plate, RX8 5 speed gearbox, ST220 sump, ST200 inlet manifold, ST220 lower inlet manifold, Crown Victoria 65mm throttle body, Mazda Tribute crank pulley and Rocketeer ECU and loom.
Back to the question, will I have a problem with the starter motor engaging the flywheel from the opposite side intended? I think not because the ring gear sits on a shoulder and is retained by set screws.


big_wasa - 16/4/21 at 11:37 AM

I don't think you will have a problem if the flywheel has the same offset.
I don't think the pinion is going to hit the ring gear and try and push it of.


sdh2903 - 9/7/21 at 12:25 PM

What do you guys have your rev limits set to (stock engine) ?

Mine is going back on the dyno at the end of the month for a map check after an engine swap and toying with lifting the limit a bit. Currently set at 7k and the power was still climbing.

Mine was 7100 rpm and still climbing,but Dale didn't want to go any higher on standard rods.

Also check your alternator ratio can handle more revs,I was knackering alternators with standard crank pulley so fitted a TTV under drive one now on the new build.


40inches - 9/7/21 at 01:12 PM

7200 still climbing


Oddified - 9/7/21 at 08:26 PM

From what i read, the standard rods are the limit as they stretch/go oval on the big ends, drop oil pressure then spin bearings. When i ran a standard engine i set the limiter to 7000rpm.

Forged rods and ARP bolts opens the door somewhat

That makes a lot of sense, I have read many times about the spun bearing problems but it has always been attributed to low oil level/starvation. Easy way for a manufacturer to avoid warranty claims.

I have a Fidanza flywheel on my 3SGE engine and the starter motor is the "wrong way round" similar to yours. All I did was to chamfer the ring gear teeth on the opposite edges and I've had no problems with it at all.


mgb281 - 12/7/21 at 07:36 PM

If you have patience they do come up on ebay, last year I had to drive up to Stafford and looked on ebay to see what was about and without going five miles off my route I had picked up a AJV6 engine, manual gearbox and a ST200 flywheel for a total of £295 and sold the gearbox and cats for exactly £400! Engine and flywheel was free and £105 more than covered the fuel etc.
Any Mondeo/Cougar V6 flywheel will fit, the only difference is a few pounds in weight but they all weigh far less than the dual mass flywheel. I have decided to go with the ST200 flywheel rather than the Fidanza, a few people who have had Fidanza's have pointed out to me that they are not always perfectly balanced on arrival.


RWD Focus - 13/7/21 at 06:25 AM

All the 2.5 V6 clutches seem to be the same,240mm drive plate.
I'm using a hybrid plate tgats paddle on one side and organic on the other,from Black Diamond.
It's the clutch they do for Noble owners.


Partofthechaos - 31/8/21 at 06:08 PM

I have another question! As this seems to be the thread for al things AJ30 and you guys have been so helpful, I thought I would add it here.

Between the banks of the older engine is an oil separator. Separating oil and fumes presumably? It is in the way of cleaning the middle of the V (not essential, but it would be nice to tidy it up). Its also looking a bit tatty, so I want to check it hasn't rusted through etc. I can't get it off in one piece without removing one of the heads, which I have no intention of doing.

The newer version of the engine doesn't have this, instead it has a blanking plate. So is it required? Have you guys left it in?

The newer version must have a breather somewhere else?

All engines need to have a breather to stop crankcase pressure


Partofthechaos - 31/8/21 at 08:42 PM

Ah OK. I had expected that the cam cover breathers would do that, in hindsight it does make sense to have one on the block too. OK, I'll leave it as it is.

Thank you!

I'm not sure on their own they would be big enough tbh?

On the earlier Jag engine with the big breather/separator as standard there is a PCV valve in the outlet, so the connections to the cam covers are actually inlets to let air in to flow through the crankcase when the PCV opens


40inches - 1/9/21 at 08:18 AM

On the post 2002 engines the crankcase breather was blanked off,and the PCV valve was fitted to one of the cam cover breathers.
I would keep the crankcase breather but gut the PCV valve.

Ah right,the pipe work onto the early cam covers is only circa 5-6mm iirc.
So they have increased the diameter somewhere as that PCV is about 10mm diameter pipework.


Partofthechaos - 1/9/21 at 08:12 PM

So is the consensus that as long as I put one of those valves on each cam cover, I can get rid of the big one in the V?

Only on one. Air in-air out


RWD Focus - 2/9/21 at 05:12 AM

Mine has a smaller breather outlet, maybe 8mm on one cam cover, near the middle and on the other cam cover at the back it has a larger elbow which is probably 12ish mm, not measured them yet but will be one of the next jobs I do, piping them back to my catch tank.

Only use a PCV valve if you are running the breather back into the inlet tract after the throttle body,as it relies on the vacuum to pull it open when throttle is closed


Partofthechaos - 2/9/21 at 05:58 AM

That makes sense. So if both cam cover vents go to a catch can without PCVs, can I still get rid of the PCV in the V?

On the early engines I think the cam cover connections are too small personally to be the only outlets.
If you read above the later engines have a larger outlet on one of the cam covers equivalent to the breather in the V on the early engines


big_wasa - 2/9/21 at 12:16 PM

I found if also depends on the engine, ware and tare and the use.

I would always fit one in the block now.


Badger_McLetcher - 28/11/21 at 06:15 PM

I took mine for mapping on Thursday down to Cooksport in Radstock, and thought I'd chip in mine - only 230bhp peak, but a goodly amount of torque. A little lower than I'd hoped, but OK for now. At least it's running right and not randomly rich/lean!

This is with Jag lower intake and injectors, homemade adapters to the ST200 intake manifold and an ST220 throttle body, custom 3-1 equal length stainless manifold and 200 cell sports cats.



I do have a sneaking suspicion that the throttle body may not have been fully opening through at least part of the session though - I wasn't allowed in with it during the mapping, and when I got it back there was significant play in the throttle linkage. It's a little bodged together at the moment, and think one of the link pieces slipped when the guy doing the mapping floored it.

Of course I may be wrong, and it's just an honest 230hp engine! Something to play around with in the future As are wind deflectors - it gets very buffety above 60!


sdh2903 - 28/11/21 at 07:04 PM

Wouldn't worry too much on the numbers they all read wildly different.

The only thing I would say is that all the graphs I've seen the power is still climbing at 7k and beyond where yours tails off a cliff earlier. I had a similar graph when my fuel pump was letting go so I think your suspicion could be right on the throttle not fully opening.

Are you using the VVT?

If so what revs are you switching it off at?


magpies - 29/11/21 at 07:48 PM

I don't understand the drop off at 6700 when others, including mine, are still climbing at 7200.

maybe fitting a fuel pressure gauge may help with the investigation. I would think it could only be fuel or air flow. Unless yours is at the wheels figures

I'll need to check the map, but the guy doing it said he got a chunk of torque and power at lower RPM, so I guess it's coming in fairly early.

Unfortunately I put the connection to the ECU on the VTech switch rather than the VVT, so there's no way to switch it back off; again another thing to sort!

[Edited on 29/11/21 by magpies]


Fuel pump is certainly another possible weak point to look at; it's always been fairly noisy and I don't have a huge amount of confidence in it. From memory there's a non-zero chance it's a fake Walbro, rather than a genuine one.

Pretty sure the figures are at the fly - I'd be a lot happier otherwise

[Edited on 29/11/21 by Badger_McLetcher]


CosKev3 - 29/11/21 at 09:45 PM

Yeah the VVT needs to go off high up in the 5k rpms,it reduces power at the higher revs.

I mentioned they sold it to Noble for the same basic engine, but apparently that didn't help.

They also said they can amend the clutch to fit the RX8 input shaft which surprised me as I hadn't heard that was required. Have any of you needed to alter the clutch to fit the gearbox?

RX8 box has the same size shaft/splines as the Ford ones,so plate needs no mods.

I might have my invoice somewhere, pretty sure it was someone called Simon I dealt with.
The hybrid plate I use,that he recommended as they use them in Nobles,does not show up on any of the listings I could find.


Partofthechaos - 13/2/22 at 08:44 AM

Black Diamond told me that they don't do a clutch for the ST200, which presumably means either it takes a standard one, or one of their other upgrades is fit for purpose, but it is likely to need some faffing about.

I've also found this one, about the same price, but it is actually listed for the ST200, any opinions appreciated! I'll be putting through more torque, but the car is about a tonne lighter, so I'm anticipating it's fine? https://www.burtonpower.com/helix-hd-clutch-plate-ford-mondeo-st24-st200-2-5-v6-240mm-70-2729.html

Not sure who you are talking too at Black Diamond, but they haven't got a clue what they are talking about.

In the link you can see all the Mondeo clutches listed,under 2.5 24V they call the ST a RS for some reason.

Partofthechaos - 13/2/22 at 11:27 AM

Thanks for the link, I hadn't managed to find that on my phone. It does clearly state the ST200 engine code, so like you say he doesn't have a clue! With that in the list I will get one ordered. Thank you for your help! I think the organic one should be fine, suspect the modest increase in power won't tax the clutch. I'm not planning turbos (yet!).


Partofthechaos - 22/1/23 at 01:44 PM

I'm hoping the experience on here will help me with my next problem! Any suggestions welcome.

I'm trying to sort the fuel rail and I was wondering if you would be able to share your setups please. I was planning to use the Jag rail as the ST200 one is copmpletely the wrong shape for the Jag lower inlet. I was hoping to put this on backwards as this will put the rail inlet close to where the fuel pipes come through from the tunnel. I was also hoping to use the fuel pressure sensor on the other end of the rail to feed into the ECU or at the very least as a way of sealing the end of the rail. However, the sensor fouls on the coolant inlet pipe when it is on in my prefered orientation.

So the options that I can see are:

    1. I use the rail the way round that Jag intended and add 1m to the fuel pipe to run it past the exhaust (not overwhelmed with this option)
    2. Don't use this sensor and try to find another way of blocking the end of the rail
    3. Use a different rail (aftermarket, DIY etc)
    4. Something else I havent thought of
Do any of these line up with how you all have sorted this?


mgb281 - 22/1/23 at 02:19 PM

Use the fuel rail off a 2.1 XType, cheap simple and fits! I bought one recently for 7.50 including postage.

Thanks guys! I don't trust my welding for fuel grade joints so looks like I need the one from the 2.1V6. I take it the pimple with the black cover near the fuel in end doesn't foul on the underside of the inlet manifold? Or does this need modification?

Thank you, that's another problem answered!


Partofthechaos - 12/3/23 at 03:05 PM

So the 2.1L rail I bought seems to be a different rail to the one you have and unfortunately it is too tall. It doesn't have the 45 degree bend near the inlet either, so definitely a different version. I wonder if they changed it with the newer engine, so there are 2 different versions of the 2.1L rail and I have the wrong one.

On another issue, do any of you have a source of electrical terminals for the sensors? I am making my own loom so need to get new ones. Even if I reuse the exisiting loom all of the clips on the injector connectors are broken so will need to replace these as a minimum.

I have the Pierberg CWA200 which I am currently fitting and planning the hose routing. However, I am struggling with the connectors. The AJ30 (and by chance my MX5 compatable rad too) is 32mm, but the pump is 40mm. I cannot find an off the shelf adapter or useful existing pipe, so I am about to see if I can find someone with a lathe. I like the idea of a lathe, but I think it more than my garage and my wife have the capacity for...

Th only option I have found is a 1.6 1971 to 1980 Ford Escort which has 32mm one end and 40mm the other, but with the bends on it this pre-made hose may not be feasable for my layout. I have one on order so I can see if I can cut it up to use as an adapter. Failing that I was wondering how you Pierberg users overcame this obsicle? I have tried to hunt around the photos on here but as ever there is never the one photo that you are after.

Any help gratefully apreciated.

This would fit https://www.forgemotorsport.co.uk/3832mm_Straight_Reducer_Silicone_Hose--product--453.html or this one
eBay

Ah thank you! So the 38mm has enough stretch to do 40mm, that does make sense. I have never actually worked with silicone pipework, this project is a steeper learning curve than expected! Glad I have your knowledge to refer to or I would never get the car finished.

Quick question for the AJ30 thread, I am installing the battery support and wondering what the smallest battery is that I can get away with. What size do you all have?

I have checked the advised battery from Tayna.co.uk and Halfords and they both indicate the same one which is massively bigger than the one wihch came with the donor car. So probably unlikely that I can reduce the physical size any further as apparently my current one is already on the small side. I have a 540A 60Ah one currently, is this about right? Tayna says it should be 840A and 100Ah. Its 35cm long! I'd rather not have to move all of the battery supports if i use my current one then find it is too small, but also don't want to carry a boat anchor around. Any thoughts?

It's going in a KitCar, very basic electrics.
I used a Varta B34 330ca, 8 years old now,started today after 3 months in garage with no chugging
It's in the passenger footwell.

It takes up the same space as the drivers pedals, so not a problem with foot space

Thank you, I saw that one in your photos but thought it would have been for the previous bike engine as its small! That is good to know, in that case I will hopefully be able to reduce the size a bit.

I used a copy of an odyssey pc680. Was more than capable. I can't find the exact one I used but have a look on the tayna site. It's about half the price of the odyssey one.

That does look like a good one, I shall investigate further.

There is no need to have a huge battery, find one that fits and order a version with the highest CCA (cold cranking amps), the battery is not required other than starting, once up and running the alternator supplies all that you need. Despite dynamo's disappearing more than fifty years ago we still believe that we need a large battery to feed everything.


Partofthechaos - 15/5/24 at 07:23 AM

Yes I suppose my question was a little vague, my concern is that I don't have a good feel for the CCA needed for this engine in our application.

It will be less than it was in the Jag as I have removed the AC compressor, power steering pump, water pump, tensioner pullies, torque converter and reduced the size of the alternator (which also doesnt have to accomodate things heated seats on start up), so the parasitic drag is going to be much less.

I was thinking that could equate to something like a third, especially in the context of light use rather than a commuter car, so I was after some real world numbers from thouse who have already worked it all out.

However, with the AGM batteries (such as the Odyssey PC680) the 5 second CCA are high enough that it won't matter (aside from prolonged cranking while setting things up for which I will have the original battery). I can have a much smaller capacity battery which still has enough starting power. I hadn't come accross this function before so it is all useful info.

In the USA there are plenty of MGB owners with Rover and Ford V8 engines using MX5 batteries, granted they don't drive them when it's cold but very often they have air con although at start up the compressor pulley is free wheeling


Partofthechaos - 15/5/24 at 09:13 AM

Yes minimal AC specific drag at that point, though it still needs a longer belt and pullies which will add something.

If a V8 can be started with an MX5 battery then I am probably over assessing this a bit! This car won't be used in cold weather either, certainly not as cold as the Jag tin top would have been designed for, so another justification for a capacity reduction.


mgb281 - 15/5/24 at 09:43 AM

I tend to use Tanya batteries partly due to their wide range to choose from and easy to see specs, just choose one with the highest CCA. I have had good results with Yuasa batteries that are smaller than the S types on a 4 litre Perkins diesel, the premium grades from other manufacturers will probably be identical. There aren't that many manufacturers just a lot of badge engineering.
