Turbo blade engines.
Built a kit to turbocharge my road bike fireblade as last years winter project.
Used a garett t25, intercooler and blew through modded carbs. Its v.reliable (5k plus miles), makes loads of power and shed loads more torque. Whole
thing cost me a tenth of the price of the kit Holeshot offered.
Have been tempted to knock out a small production run of budget DIY kits with instructions.
Just wondering wether you think there would be a market for this amoungst you bike engine boys?
Kind regards,
Doug.

Sounds interesting - can you give us some more info? like estimated price and tech info?

Would it be any more bother to do it for a ZX9R??
Also post this on the Yahoo BEC list:

You may get more interest there....

I have a mate who's currently considering a nitro solution, I suspect a turbo would catch his attention. Any chance of possible price? Any
pics appreciated and and numbers on power/torque etc?
Thanks

I'm with Jasper, any chance of a ZX9 version?

Me too!
I guess it must be fairly standard (maybe a different pressurised airbox to fit different carbs) so what about a Thunderace?
I might be interested next year (haven't finished the car yet!), especially if the price is good.

Nahh stuff you kwakker boys, I would be very interested in the blade turbo kit.
Any idea of a guide line figure ?

Talking 170bhp upwards to 250bhp depending on boost.
With just a different head gasket you can run 10 psi which is about 195bhp.
Kit would include,
Manifold
Plenum chamber,
Exhaust flange for turbo exit
Head gasket
Jets
Fuel regulator
Cd with instructions, info on which turbo and fuel pump to get from scrappy and carb mods.
Optional extras, intercooler, ready made pipe work, dump valve,
Will post some photos of the setup i run on my bike. They show it all bolted on the engine before it went back in the bike.
As for cost... would have to think about it but it would be hundreds rather than thousands, Holeshot kit (£3200)!
Do you still think there would be any interest?
Could prob write a set of instructions on cd on how to produce one from scratch for the ZX9 boys?

Hey Doug,
There will be interest if will be priced as you say and if it will be developed to acseptable stage - reliable and easy to install.

For those interested in existing implementations, look at the Holeshot website (http://www.holeshotracing.co.uk/) and go to
"Tuning"

Hi
Doesn't the turbo version of an engine have lower compression pistons?
Too much is just enough

From experience and knowledge of car engines compression ratios drop from between 9-10.5:1 on a naturally aspirated down to 8ish:1 on a turbo
version.
I don't know if this is the same for bike engines, but assume with too much boost you could risk detonation as a turbo engine uses the boost
pressure to generate the compression in the cylinder (hence use of lower compression pistons).
You can get away with normal pistons if you don't run too much boost and/or run on a hi octane fuel (super plus or better) which will burn
cleaner/better and hence not lead to detonation.
I've heard as a rule of thumb, once you get above 10.8:1 you should use a very good qulaity high octane fuel to avoid detonation. generally race
engines only.
(obviousley this is for petrol engines, diesels are higher compression but same theory applies)
all IMHO

An decently mounted intercooler will reduce intake charge and supress detonation. Simple water injection (methanol based windscreen washer fluid will
do the job) system reduces combustion temperature on higher boosted motors.
Water Injection Link
Intercooler Theory Link
You can retard the ignition a couple of degrees too.
I don't think us Locosters need worry too much about changing pistons. Could always buy a thicker head-gasket!

Doug,
I'm intererested to know, what made you choose a T25? Was it any particular technical quality or do they come attached to cheap donors? I
hope it's the latter!
Have you had any high-rpm boost problems?
Cheers,
Neil.
