The evo actually weighs 3,321 lbs, so once again you are wrong. And from my research the curb weight on a 03 cobra is only 3665 lbs

300lbs isn't that big of a difference on highway racing, especially with the better gear ratio the 6speed cobra's have. The car shouldn't have put that much of a hurting on those cobra's... unless it's running more boost then what it dyno'd at...
