does anyone know what kind of psi a tpi350 should have with 58cc heads and a compression ratio of around 9.5:1?

 

Cam makes a difference too in what the reading will be. You should have over 150psi though, beyond that its a matter of how the engine was built.

Actually I just read your other post, 195psi is pretty impressive... Probably a small cam or not much overlap huh?
