My regal Gs ran a 14.81 on bald tires with nothing more than a CAI and GP stock dual mufflers. I think the regal would pull from a dead stop, and the cv would own it past 100 mph, i've had the CV up to about 135 mph.
as for the Mustang S/C i think i should've clarified i was talking about turbo numbers. Turbo's for the most part make more hp per boost from what i have seen. Turbo > Supercharger
also wanted to add that the CV is about 600-800lbs more than a mustang gt 96-04
