Winter upgrades nearing completion, TURBO now on
Been busy upgrading, as usual running late as have rebuilt the front end with wider bones and now a Turbo is coming together
Installed_rear_june2009_small
Installed_top_june2009_small
Installed_side_june2009_small
It seems to take me forever to do stuff these days, the manifold was a struggle.
Thanks to Scootz for this piece of kit, it seems pretty cool, no oil or water pipes or wastegate required as its got variable vanes, planning 8PSI to
protect the gearbox and clutch.
Anyone know what Holeshot do to the cam timing on Fireblade engines, I believe they advance the inlet....
Cheers Mark

You need to cut slots in both the cam timing sprockets - they need to be about 9 or 10mm from memory.

That's just showing off having the turbo on show, wish i had thought of that when i did mine was a nightmare to keep it in the engine bay

Bit afraid to stick it inside TBH, no watercooling or oil so it must get pretty hot.
Thanks for the number Steve, I,ll call tomorrow first thing.
Cheers Mark

Very nice mate - looks good! I'm thinking I may have to have a partially exposed turbo as well, as it looks like trying to fit it within the bay
will severely compromise manifold design now that I have moved the engine back 5 inches
Are you supporting the turbo at all? It's a heavy lump of a thing to have dangling on the end of 18ins of hot tubes - it'll probably need
some support that allows a bit of movement as the manifold expands and contracts. I've see some good home-made supports that use an old valve
spring welded to a bracket.
Does the variable vane unit use an actuator to vary the vane position? How about boost control - is this a normal wastegate arrangement?
Cheers,
Tom

Hello Tom
Its a third in, a very big lump sits behind the main body that controls the vanes, this is why its so far forward to avoid knocking into the oil
filter and drops below the main frame diagonal.
No wastegate as it directs the exhaust on or off the vanes negating the need. I will stick on a BOV.
It also has a number of vacumn points on the actuator so I will need to experiment with these as it came without instructions.
No bracket as yet, next weeks task.
The engine was a 893 originally, the bumps in the paint are where the rod exited last year so its now a 918 lump.
Megasquirt EFI using 954 throttle bodies

I envy the passenger, he'll get a good view of a bright orange turbo......
fantastic stuff, looks great.

You fitted EFI to a 893 thats now 918...awesome
As there any reason you decided to go EFI as although my knowledge is limited with turbo setups I thought you could run the carb setup?
How did you get a base setting for the megasquirt?

Fitted because its easier to tune and I had a megasquirt box lying around from a Rv8 install.
No faffing about with jets, I tuned with a JAW wideband sensor stuffed in the exhaust.
Bike carbs previously were dynojetted with free air filter, fitting the EFI improved power and torque above this setup to the degree that it caused
the clutch to slip.

Made the exhaust Sunday afternoon, just got to plumb in the intercooler now so anither half a day and I should have everything in the correct
place.
Task after that is to insert some rods to stop the inlet plenumn bulging out and improve the inlet manifold so the TB's do not seperate from the
head.

Intercooler in, after reading corky bells book I welded some external ducting to stop spilling air.

Its been a busy few weeks, I found my megasquirt was so old that I had to replace the MAP sensor, it had the earlier 115kpa sensor so now replaced
with the 250kpa version.
Cars all up and running so I decided to test the set up to ensure it would hold pressure and not overboost so jacked the rear wheels off the ground,
stuck it in 6th, flat out on the throttle and hard on the brakes!!!
Result, as boost builds (which is very quickly) I cannot hold the revs on the footbrake, smoking calipers after 10 seconds but confirmed 6psi boost
from 3000 rpm building to 10,000rpm lambda values a bit weak but not piston hole time.
So have added a bit more fuel at the top end, this has added a bit more power as I cannot get near WOT and hold it back.
Next job then, book a track day... ye haw.
NB/ lots of red hot manifold and and burning paint.

Managed to get on to a private road today for a little try, the performance on a completely standard engine running around 6PSI is
*****UNBELIEVABLE*****
Not a lot of boost below 4000rpm but then it comes in very quickly and shoves the car forward, it makes 5th and 6th gears feel like 2nd and 3rd.
Previously the car would break the rear wheels free under acceleration in 1st, this happens now in third doing ~50mph
Then the bad news..... The engine was sold to me as good, it overheated really quickly and upon inspection it’s been frozen, creating a couple of
cracks under the exhaust ports which have been cunningly filled with some kind of putty...
It runs perfectly so I will drag out at the weekend and have a go at welding these area's, at least if the turbo blows it up its a scrap engine
I suppose.
Was hoping to do a track day at Woodbridge, will have to can this idea so aiming for Brands evening on the 15 Aug now.
Car also sounds great, much quieter than before with a satisfying Psssshhhh as it boosts up, at least my hard work has not been in vain.
Cheers Mark

Well done Mark - I bet you are glad to have it finished!
I thought that engine was suspiciously cheap - still, if you can't fix it, at least you can find out how much boost it will take before it goes
pop
If I'm around on the 15th I'll pop along to Brands to see how it goes. Didn't know there were any private roads near you ;-)

Thanks Tom
It has taken a lot of time, for what looks like a little bit of effort, but initial impression is very worthwhile.
I,m glad you pointed me in the boost it direction, it just seems more satisfying cobbling bits an bobs together and getting real power gains, maybe as
much as £300 to transform the car.
This was also the first time I have driven with the wider front end, this also feels good, to the degree the back end feels a little loose now (or
could just be the power) so some 205's and arches may be called for.
I,ll let you know if I book up brands, if I can sort the engine out this weekend then should be good to go.
Cheers Mark

Brands, 15th, Ill come watch!!
That is a good bit of craziness! If you book it then a few people should come down to watch. Dont want to put the pressure on to perform!!
Good luck with the rest of the build and fixing the cracks.

Looking good Mark
I would be interested in a list of components you have put together and the costs involved, to turbo your engine.
Were the parts all used/second hand or otherwise ?
How are you managing the fuelling ?
sorry for the pleb questions, but a link to your build album if you have one would be worth a look too..
cheers

Will not be brands now, had a look the date was wrong but its fully booked anyway.
I am afraid there are no build albums, as close as you get is on this forum.
Costs:
TB's were £85 ebay
Jag injection pump £25 ebay new
Megasquirt, squirt only ~£100 years ago
JAW wideband ~£125 (not recommended)
Turbo #1, from a volvo £5 but not used
Turbo #2 from Scootz, £250
Old exhaust manifold to chop up £25
Inlet manifold, Bit of ali scaffold lathed and welded.
Plenum, rolled a bit of sheet around a drain pipe and welded ~£10 scrap
RS Escort intercooler, £70 ebay
Intercooler tube, old bed frame free
Silcon hose, Turbo D landrover £5
and some clips, £10
That's it, so really! Engine is untouched, as bike engines are designed to run on american fuel with Optimax you can boost to 6 - 8psi without
issue.
With megasquirt I had a decent non-turbo map so I just extroplated the table out. You then disable enrichments and datalog on a gentle drive and feed
the results into megalog viewer, this generates a new table, load repeat using more revs and after an hour you have rolling roaded the car youself.
Just start off rich so you do not blow holes in pistons.
Cheers Mark
