I have a friend with an 04 Cobra, he puts down 450rwhp and the motor is stock barring an after cooler and pulley. A supercharger is going to add more than 70hp on a V8, unless it's a really weak one, and that's assuming you were referring to a stock C6. That pic is a Z06, which puts down more than 450rwhp stock, add the supercharger and the power/weight ratio far outweighs most Z32s. It would have to take a particularly bad driver in the Z06 to lose in that race.
