 What is the compression ratio? Also what RPM range or peak HP? That's some stout numbers already!

Thanks for the corrections, Glenn.
That's what I had guessed but wanted to make sure. Here is Pipe Max data on the headers: Quote:
You're running gasoline I think? Possibly try alcohol if so?

I tried alcohol and got no improvement. |

I am running a Rossler low drag competition trans. It may not be as fast as a Liberty, but I hope I can overcome the difference with other changes. |

Sorry, I rechecked my paper work and the compression is 15.4. It will be hard to get much more. The piston domes are from molds of the chamber. My intake runners may be a bit to long so maybe a sheet metal intake will help. |

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
