You're right. But a byproduct of a turbocharger is incresed backpressure. This will make the engine behave more like it is at sea level. Versus supercharging which will not increse backpressure. If you ran a superharger on a 2 stroke you would need to time it very very conservatively. At least if you expect to retain any of benifits.

Hmm... Actually. If you just reduced the size of the stingers on the tuned pipes you might be able to compensate. Hmm.... You'd be doing the same thing as with the turbo, effecively running the whole engine at a lower altitiude. I think that needs some experimentation.

What does turbocharging usually do to the HP curve on a 2-stroke? Does it make the curve steeper?

Thanks,

That's a very good question :-) Anyone have a dyno chart of a turbocharged 2 stroke?

check it.....

Interesting, turbocharger after the tuned pipe. 142hp on 350ccs.... Those are some impressive numbers.

Now that looks like a fun little bike!! Thanks for the link.

I like the idea of a self contained oil system like on the Aerodyne turbos.
