How much HP / Boost out of a stock engine? - Page 2 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

There are a bunch of 500+ boosted HP 6.2 cars on the road that are stock internal(mine included). Doesn't the LS9 have the same chain?

My engine is BONE stock inside, has never even had the intake or rocker covers off. Running 12.5 psi AND a 125 shot. No problems yet. It shifts at 6300, I think a lot of problems and wear is rpm related. I'm about to add a Mr Freeze meth kit and take the boost up to 14 psi. Not sure what the power level is, I'll get it to the drag strip this spring and use a mph/weight calculator to find out. I'm guessing between 650 and 700 rwhp now, 700 to 750 rwhp when I give it meth and 1.5 psi more.
