Correction: the 6.2L V8 with a a twin-turbo has 1,063-HP I quickly have forgotten doing so many RWD cars with a supercharger instead of the turbo. My bad, but now testing the 6.2L V8 the power draw isn't much different than the 3.8L V6. I can use basically the same gearing only slightly increasing Final Drive to 155.5 mph vs the 150.5 so a 5 mph difference isn't much a difference at all.
