Fred, since Hydro Tec is in the engine building business they likely wouldn't give you the spec sheet unless they did the work. I think they have the only copy. I know several other guys got more horsepower, Steve Cooler for one. He was in the 130 hp range as I recall, but did have issues with blowing head gaskets. Popa Sam can build a mean 90 for sure.

Just to get back to the original thread. A racer e-mailed me askng me why having 200 lbs compression as a problem. It makes power!
My answer is: It will get you more power off the dock. It hurts you top end wise because the motor is actually fighting itself because of the added compression at the high RPM, so it slows you down. It also results in a much shorter engine life, especially if you running stock parts. It is one reason why the Yamahas break a lot of parts. It is also why I find it difficult to believe you can get 200 lbs compression legally in a stock 70 CES and if you could, It would slow you down. Again just my opinion.
