I thought it would have been a cool dyno comparison, but these two cars are completely different.

Once we get a chance we are going to do a little 40 roll.....His car isn't the best from a dig, so a roll is the only way to compare the two cars

Also corvette has the good x pipe , my car still has a shitty y-pipe that merges to my stock mid pipe that measure 2 7/8 at the clamp. After seeing chrs1313 pick up 15 rwhp from a good merge i've been getting some piping ordered up. I plan to ditch the catback and do a 3in into 3.5 in and run the dump to my rear axle so that no other bends will be in the exhaust

Always cool to see how different cars/setups compare on a dyno. Let us know how the race goes.

Might be a decent comparison if you post the SAE #'s.

My car ran a 10.5 @ 127 on motor, before his heads and fast 92 he was 421 rwhp running 12.1 @ 121 I think, add 40rwhp he should be in the 125 trap speed range.
