Automatic Supercharged corvette questions
Hey I got a 2007 C6 Z51 A6 corvette. Everything about the car is stock except for A Paxton Novi 1200 supercharger with 6 pounds of boost. It was dyno'ed at 527 horsepower with 519 torque, My question is, would an automatic with a lower differential, being at 2.56, be faster than a manual with a 3.42 because my 1st gear ratio is 4.02, versus a 2.97 for the z51 manual, if both cars had the same wheel horsepower, of course. I am highly considering giving my car a 3.15 diff, but that would be insane power on an automatic... I mean i think it makes sense because I redline @ 46 mph whereas the Z51 manual redlines @ 49 mph.

Your car would feel great with 3.15's! We have already done a few ECS SC A6's with them and it really makes a very nice difference without feeling "over geared" in anyway.
