Chuch have you looked at any expansion chamber stuff?? Roger
Mandiville was using some at one time in the WSC cars..They
were big but he was pretty fast too. I think if I was going
to do it I might look at some. I might even have some
software somewhere that does that sort of stuff.. I bought
it when i was playing around with some Rotax stuff.. BTW who
makes the best 2 stroke water cooled stuff now?? Any bikers
out there that might know?? Oh yeah that can be bought not
just admired..
