otherwise it would not leave the f430 standing. the 430 has 490 hp and f1 gearbox.

They dynoed a SPF a few months ago at Hillbank with a Roush 427R, and it made about 480 at the rear wheels.

yup i agree. it has to have far more than 3-400 horses at the wheels.
i have a 997 gt2 and a 997 turbo with 530 and 480 DIN hp.
by the seat of the pants feel, the cobra is much faster in acelleration. for all i know driveline loss is usually around 15%......20% at the max with lots of auxilliary stuff.

Take it to the drag strip and it will make a pass equivalent to 380 wheel HP.

Dynos can be exaggerated. Trap speed is reality. There are enough 427Rs and 427IRs out there that have been to the drag strip to know the real wheel HP with Superformance headers and Superformance side pipes. The same goes for any engine in a Cobra.

Here are a few cars that I've had opportunity to see race each other as well as race along with my Cobra with Roush 427R while it was between 400 and 475 wheel HP during assorted power gain modifications. Other than these cars there were perhaps 4 times as many that gathered about the club events to compare as well. I'm reasonably certain about this.
