How much compression is to much for a turbo
Just wondering how much compression is to much for a turbo? I have around 13.8 to 1.

GMAN005, Not worth installing the turbo on the engine with that compression ratio.
Unless you want to run methanol and less than 10 psi of boost pressure. But you would have the "cool" factor. You are a racer, not a Dairy Queen cruiser. TV

I’ve heard that many of the really fast guys run high compression (13-1) and e85/m1 but I wouldn’t try it. They have tons of time and money to get it right.

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.
