Hi,

Has anyone on here turboed a bike engine?

What turbo did you use?

How did you add more fuel? 2nd ecu, up fuel pressure?

Any info would be great. Ive seen the work that the likes of holeshot etc do but would prefer to do it all myself.

cheers

I'd be interested myself on this.

To wet your appetite I found this very entertaining video on the Dax web site showing a Rush with a turbocharged hayabusa engine:

Check out "jambojeef" on this forum,Ive been watching his progress with great interest,on his turbo cbr 1000,he's carried out all the work himself,and done a great job on it,would be a good starting point.

oh my god i need one of those!!!!!!!

Shame the cameras looking the wrong way most of the time.

I realy need to turbo my engine, im hooked on this speed thing.

I too am considering sticking a turbo on my fireblade (919) lump. T25 should provide enough air for 200bhp at about 6psi. Just need to get an airbox to pressurise the carbs and a manifold and an oil feed and return (sandwich plate). Apparently Holeshot use McXpress (Swedish) for their kit. You can buy bits separately I believe (might do this with the airbox).

Also they do thicker headgaskets to drop the compression a bit or I've heard that some people run 2 standard gaskets to achieve the same thing.

If anyone else is thinking of doing this (especially a 919) I'd like to know so we can share ideas and perhaps save money on bits or getting manifolds fab'ed etc.

I saw a turbo'ed 919 in a kart at santa pod a while ago was chatting to the owner but had to go as I was racing myself.

Id be interested in doing this eventually with my Blade RRV although i must admit driving a turbo'd car im quite interested in the Nitorus option as well.

I just want one for me bike on the road

another chap on here had a turbo'd bike. Somewhere darn sarf. That garage19 fella.

interesting stuff have to talk the mrs into it first though

if its a carbed engine then its fairly easy to seal up the carbs and rejet to suit the bigger hp and using a boost related fuel regulator (it lets fuel pressure rise with boost). for injection most of the time a power commander should be enough to adjust the injection timing.

just be careful to watch compression ratio as the new bikes run them very high (13-14) which will not work with a turbo so you will need a decompression plate (like a thick head gasket)

Guys,

If you are serious about doing a tidy Turbo instilation you shoud talk to these people. (www.qpeng.co.uk - Jon Saunders).

Jon developed the Turbo charged Hayabusa for the radical so knows what he is doing.

They can supply you with the equipment to fuel inject your bike engines at fair prices. I believe they will even do the engine loom for you if you do not want to do that yourself.

Feel free to tell him I passed you on & I will be intrested in your feedback.

Go Turbo......
