[QUOTE="FordMoCo21, post: 16310138, member: 104388"] I don't find it that surprising considering they have the car trapping 123+. You don't do that with a 3600lb car making 460whp, it's not possible. I have a feeling most customer cars will be around 540whp on a dynojet, kind of skewed with no real 1:1 ratio to dyno in though. Time will tell, either GM shipped cars to be tested with a boat load more timing thrown at them, and the customer cars will be slower, or they are very underrated. Power to weight is literally everything for trap speeds. DCT, manual, auto it doesn't matter. Maybe a 1-2 mph margin for driver mod in a manual or an insane trans like in a Porsche. C7Z06 traps 127 with 570whp and 3550lbs, C7ZR1 traps 133 with 670whp and 3600lbs, New Ford GT traps 131ish with 590whp and 3300lbs, 13/14 GT500 traps 125 with 590+whp and 3800lbs. [URL='http://www.wallaceracing.com/et-hp-mph.php']ET-MPH-HP Calculator[/URL] (I would say ignore the comment it has about "driver in car on the line". The numbers are dead on if you just put in curb weight and dynojet whp numbers.) **the above calc also worked for my daily. 3550lb(without me) Paxton 3v, with 450-460whp trapped 116-117. Plug in 3600lbs (WET weight) for the C8, and 540whp, and boom, traps 123. The DCT may be a crazy anomaly in all this, gaining it a few mph.
