    Question: engine compression vs adder boost

    Not knowing much about power adders......

    Somebody mentioned (Hemi31) that you dont want to run greater than ~17 PSI CR for a street motor.

    What is the difference if you have a 10:1 motor with a 7 psi boost whatever(turbo/supercharger) vs

    a 8.0:1 motor with 9 psi boosts?

    6-8 psi of boost is just a tease. Run 15 psi for a thrill. At 15 psi, you basically double your na hp. Keep your boosted compression ratio near 17:1 so you can still run on pump gas with a little help from meth.
