H/C/I C5 coupe vs H/C C5Z06 We had a good run tonight. My C5 coupe (480rwhp est, needs a retune) 6spd has Ported LS6 heads/MS3/FAST 90 with a passenger and the C5Z (470rwhp) had milled AFR 205 heads/G5X3 no passenger. I let my buddy drive my car. My car is about 300lbs heavier (coupes are 100lbs heavier than fixed roof designs and me, passenger 200lbs) than the Z.We go from around 60mph, 3 honks, the Z gets a half car jump and pulls another 1/2 car from there due to his 11:1 compression and better area under the curve vs my 10.5:1 compression. I'm was a full car behind (my front bumper was at his rear bumper) in 2nd. Then in 3rd gear I inch up a tad but still on his rear bumper. 4th gear is static no one pulls on anyone and we shut down at about 150. It was a good run, my car lost by 1 car, but eventhough the Z got the jump, I think the race would have ended with me being a 1/2 car back (my front bumper on his door)and still losing anyway. My car just does not have enough power to inch past it. If the guy with the Z reads this, good run man I enjoyed it.

Almost sounds like your putting together a court case.
