Most of these cars don't have long tube headers with x-pipe. Car dyno'd 640 rwhp with exhaust only, at VMP. Then we added the upper pulley / tune / throttle body and made 730 rwhp. Next I want to add lower pulley and hopefully squeeze out 750 to tires which I will need to pull the vette because we are damn near perfectly even on the v- box. People can talk about me making more power than the vette but as most know it takes a lot to make up a 700 pound weight difference. I will admit the Shelby is a heavy pig as someone called it.
