Rescued attachment air vents.jpg

the middle one on mine runs straight to the plenum, the left and right run to the inlet pipe of the plenum, one on either side, there are pictures in my archive.

How have you attached the plenum to the carbs? did you remove the plastic tops and bolt directly on to the carbs? have you got a picture?

Andrew.

fitted to tops as you say, will chack out you pic's ta.

top

Ive been having trouble getting mine to seal, im running short rubber joiners but there isn't a lot of room on the plastic.

I thought about doing the same as you, but there seems to be a recessed area on the bottom of the plastic part and I didn't know how it would affect the jets under the trumpets if I put a plate directly on top, mine is on a blackbird but I think its the same setup.

[Edited on 24/2/07 by dilley]

looking good! youll soon run out of space though especially if you fit an intercooler and pipe work

just dropped it in to see if it fitted.
IT FITTED

not giong to run intercooler yet, going to see how it goes, yours looks good though mate.

did you leave the trumpets ?

where do the other pipes end up.?.

As you look at the plenum inlet the left and right 10mm pipes go to the left and right feeds on the carbs, the middle one inbetween the 4 carb outlets goes directly to the middle pipe that is inbetwwen the carbs, if that makes sense, that should cover the 3 you needed to know.

I missed one, the bottom right one in the picture goes to the fuel pressure regulator.

so if i take the four carb air feeds to one of my 10mm pipes and the other end to to my carb breather, then all i need to to is a new outlet to my fuel pressure reg. Or do i need to do that.?.

You should probably use one. Did you know that tthe charge temp will be about 120-150 C when it leaves the turbo!

Are you using a mallapassi fuel presure reg?

---

Yup, that hot!

The metro one is a malapassi item.

Same as used on the early carbed lotus espirit turbo.

yes you will need a feed from plenum to regulator.

How much boost are you running?

My car running 7 - 9psi has an 'uncooled' charge temp of less than 40deg on 18 ambient.

Couldn't sensibly fit an intercooler so went for WI... With that running, the charge temp drops to around 25 deg on 18 ambient with 100% screen wash.

All temps measured with a thermocouple in the airbox inlet.

will look out for an intercooler may be on ebay.

so i need to put another feed for the regulator.

are any of you using a air fuel ratio meter with a lamba sensor fitted.

and i dont know what the boost will be yet, engine needs a selector fork still so may even get some turbo pistons.

You don't need turbo pistons, just two genuine honda head gaskets.

That is what haleshot used to use until they sourced a custom thicker one from the states. They ma sell you one of these if you ask.

i found holeshot a bit, errr, not very forth coming for info, but hey there in buisness to sell things. But im ok on that.
Will only go the MAD route if the gear box is goosed, but for now 2 gaskets will do me fine.
So how much boost you got garage19 ?.

downside of the intercooler is increased lag as there is a greater volume to pressurise. You want to work out if you really need it or not, obviously at very low boost its totally unneeded, at high boost its very much needed. All IMHO

AT 0.5 - 0.8 Bar you really don't need an intercooler... Apart from you can't fit a big enough in a sevenesque to make that much difference at that level. Hence my temp post... No where near 100 deg+ going into the engine!

I've found WI a simple and effective way to the job - well a lot more than the job actually.

You'll need to fit a 1.7mm COMETIC head, gasket rather than two standard ones, to drop the comp a tad. Unless you're going for 1.1 Bar+ low comp pistons are... expensive and not needed.

You also have to concider the clutch. The turbo puts a lot more torque through it and simply bunging in the 'Uprated' or 'Heavy duty' junk that's available really won't do the trick. Think less than 100 miles between clutch changes.

At the levels I'm running there are fixes out there that work, but if you intend on running more than 0.5 - 0.8 Bar you will need to redesign the whole clutch system...

Edit for:

My car did run with a 1ltr intercooler - with no lag. Took it out beacause of cooling issues... So with bike engines, unless you're running a huge turbo that's not matched to the engine I don't think lag is much of an issue.

Rather the other way around in that the power on a N/A engine comes in a what - 5-6Krpm... with my system the power really starts at around the 4K mark.

[Edited on 25/2/07 by mb893]

so then, we cant decide on an intercooler.

Ive just bought a facet red top pump.

need to weld on another pipe for the regulator.

are any of you using a air fuel ratio meter with a lamba sensor fitted.

cometic for a new thicker gasket.

owt else?.

i have a lamba sensor position on my exhaust for setting up purposes.

Plug it into your PC and you get it all on the screen. Perfect for initial setting up and health checks.

Can run it into a DVM too if you want a standalone display rather than a laptop.

Personally something like
http://cgi1.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=130081926213 (although width could be an issue)

or

http://cgi1.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=180087564284

Which are nice and small

Really shouldn't need to be over £30 for a small intercooler. Just try and get one without plastic end caps as these generally blow off at high boost levels (not that you'll be near them).

they will...only once though

I origionaly mounted min in the nose cone but had cooling trouble, I have now moved it under the bonnet in front of the scuttleDrivers side and mounted a scoop aboveit, so far so good.

I wouldn't cut a corner on a gauge. Autometer (not Autogauge) are good quality and cheap from USA via eBay.

You may struggle to find one which gives you a 9-10 psi max, or even 1 bar, and you don't really want a 2+bar unit as you'll never use more than 1/3rd of it.

Autometer do a 20psi unit as their lowest afaik.

Shouldn't be more than £8.00 posted from the US and the gauge will only be £23 on the current exchange rate. Similar gauge in the UK will be an easy £45 + delivery.

May be some cheaper 2nd hand on eBay or other forums.

dilley - 1/3/07 at 01:28 PM

I have an oil filled gauge that I got from holeshot, its suppose to be megga, I only changed it because Im running turbosmart e-boost which has a digital read out. I also have a another gauge both are as new condition.

Does that mean you may have one for sale Mr dilley.

welderman - 1/3/07 at 02:22 PM

also do i need to get the exhaust gasses out asap, ie if i have two exits one 50mm and the wastegate is 25.
I can weild a 75mm tube over the 50mm and 32mm over the 25mm hole so it escapes quiker or do i just stick with a 50mm one and 25mm one.
These exit pipes will be joined after about 60 mm.

Looks a nice construction, as a subaru owner tho, can I say heatsoak?

Make sure you have good scoops

---

Simon - 11/3/07 at 10:59 PM

No worries about heat soak. Air in at top, through i/c's then vented out of sides (these are ducted under coolers). Note side panels are proud for air extraction with forward facing vents for air entry (primarily for air to filters). There's a vent on top of bonnet behind rad, and nose section slightly wider to allow for air extraction

Maybe a bit of overkill
