Default Re: Could a 10.25to1- 10.5to1 motor live long with 5 PSI of boost?

More compression + boost = more power. As long as you have the octane to support it. With 10.5 you should be fine with 5 psi. Also there is more to it than your static compression ratio. Your dynamic compression ratio is really important here. Not sure what the specs are on your cam or how you have it installed but that'll play a large part in how much boost you can run.
