Installing vortech supercharger w/aftercooler running 9lbs of boost on a 2006 gt. New throttle body already installed (dyno proven by my shop to produce xtra 5 peak rwhp and 22 lbs of torque. Have already purchased jba ceramic long tube headers with h-pipe w/cats and magnaflows. Problem is I believe these mods will produce more than the 450 rwhp that has been identified as "dangerous" by several members of this forum. (all this is based on anecdotal evidence of blown engines at these power levels.) My question is: Is it the horsepower that blows these rods and pistons or is it excessive boost levels. In short, assuming 9 lbs of boost is safe, does it really matter how much horsepower the engine produces as it relates to engine longevity. If there is anybody with expertise on these issue please respond as I think others might have this question also.
