Turbo Bike Engine
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
Carnut

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.

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.

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)

I know a man who can
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......

I assume the carb on the bike uses some sort of float(s) ... make sure that the floats in your carb are either sealed brass, or neoprine. If they are
just tin/alum foats they will be crushed by the pressure. Not sure what that paticlar bike engine uses stock, but I know from blow-thru carb setups
on chevy small blocks that neoprine floats are your best bet; they'll float well and won't get crushed by pressure. Otherwise your plan
looks good.
Not sure what comes wth that kit you mentioned, but it should be reasonably easy to weld together a sheetmetal box around your carb. You could also
consider going a pass-thru route; but that would effectivly increase your intake runner length substansially. (ie: the carb is on the suck side of the
impeller)
The biggest paint in the ass is always sealin the linkage thru the box; it all has to be air tight through brass fittings with plastic coated cording
thru them seem to work well to get a good seal; just check them every month or two to be sure the brass hasn't eaten thru the plastic coating
yet (Sorry for the novel)
