Problem is that thing does NOT weigh what a Shelby off the showroom floor weighs. If they really were pushing 2 tons (gross weight of the new Shelby) down the quarter in that time, that car would have to produce somewhere in the neighborhood of 880 RWHP which according to them they are not. Taking weight out is the same as putting power in and 4000 lbs is a LOT to push around for any motor. A 4000 lb car with 664 RWHP should be clicking off 10.5 sec quarters at approx 128MPH. Obviously they took quite a bit of weight out!!!
