Yeah, I understand that, but mph tells you more than that. I have a TBSS that would outrun that Cobra running a 12.4 (before 418 ci LS3), but my mph is like 107, I'm AWD so yeah I have traction, but the MPH tells you that 1) I'm too heavy, 2) i'm not making as much power. These cars are fairly similar in weight, so it can't be that, its either test conditions + power difference or just power difference. Running 3.8mph faster only is not a traction limited factor. MPH is HP, and 3.8mph suggests either the testing conditions between the two were WAY WAY different, or their really isn't that much of a power difference like the dyno suggests.

My point is, if the GT500 dyno'd at 511 rwhp, then why is it only trapping 114???? With almost 150 rwhp over the camaro, it should KILL the camaro, but its only trapping 3.8mph more according the Edmunds (who tested both cars with similar testing methology). We will soon see when folks actually get to take many cars to the track and we can compare lots of data, but based on what I'm seeing here, something aint' kosher.
