the red turbo bike is the only one i have seen.
i am sure he has more than one bike tho :silly: .

Do you guys think maybe theres a way to make your own kind of Turbo/Supercharger? Like maybe air scoops that come out of the airbox and catch air at high speeds to blow into the carbs?

that would be ram air kt.

turbo or supercharger is the preffered method of getting "compressed air "into a combustion chamber.

I think the 1990 ZX11 was the first to have a functional ram air, it added 7-10 hp on top end (175 mph or so).

thats so badass.

Both turbo and supercharger force additional fuel mixture into the cylinder.

Turbo -- Exhaust spins the Turbo without using engine power.
Fresh air is used in the fuel mixture. Exhaust output isn't part of the fuel mixture.
Engine must be spinning for exhaust pressure to spin the turbo. That's the reason for turbo "lag" from low rpm, which occurs until the engine gets going fast enough to produce sufficient exhaust pressure to spin the turbo. Lower compression pistons are fitted, which allows larger combustion chambers for the turbo to force-feed. The initial low compression also contributes to the lag time off idle. And when the exhaust pressure gets sufficient to spin the turbo, then the magic happens.

Supercharger -- Uses some engine power to force-feed additional fuel mixture into the cylinder.
It performs immediately off idle, and without lag. Instant magic.

At least that's my simplistic understanding. Others will have better and more competent explanations.

Good Fortune!

If you set up the right turbo/carb lag wont be a problem,hanging on might be another story! :woohoo:

supercharger takes hp to turn,not tunable like a turbo without a lot of work to overdrive/underdrive blower.
turbo run it on pump gas with a few lbs of boost ,idles like a stocker.
you want to go hot rodding with a turbo bike real basic:back off the timing/adjust boost-waste gate and dump some good gas in there,instant dr jeckel/mr hyde.
to put it back on the street just reverse procedure in 15 minutes or less with a little practice

so turbo is just all around awesome as far as tuning goes. Theres actually a turbo charged KZ1000 That i know of sitting in a barn in Moville. Ill have to ask the guy thats got it what hes gonna do with it. I guess it needs a top end rebuild though. It sat for some years and the PO i guess fired it up with no oil or something like that. I guess your supposed to put oil in the cylinders before starting if the bike has sat a long time? makes sense since all the oil runs down into the crank case and the cylinders would run dry for a second on initial start up. i believe its a 1979 KZ1000.

*Typically* a supercharger gives more oomph at the lower end of the rpm range than a turbo, but it all comes down to tuning. With a turbo, the exhaust gases have to flow at a fast enough rate to get the compressor going before you notice a difference, but it doesn't rob HP like a supercharger can.

Both cool technology. You should do a super/turbo combo. Just post pics for us.

Its a matter of sizing the in/out of the turbo and having the right carb to feed it.
The facory z1r turbo kits were crude to say the least,and the carbs sucked
A supercharged motor is making power from the time you turn the key,at the same time its also making a lot of heat .
where as the turbo is basically a mild mannered easy to start 8:1 motor that will sit and idle in stop and go traffic much easier than a blown motor,if you combine it with some sort of electronic fuel injecton youd really have the best of both worlds.

I think Jeff told me it would cost me about $3500.00 to set up a nice turbo engine.

Here is one ready to go. Roy
