Unless you are looking at 400 + hp i'd say 4.10's or possibly 3.90's.

I run 3.90's with 373 rwhp & 528 rwtq, and wouldn't change a thing. To me it's the perfect gear for my setup and power.

Since you are doing a PI swap and supercharger, i thing either one would be ideal.

A steeper gear (within reason) is just going to be more fun period!!!

Do you hit the highway much? If so get the 3.73's, if not then 4.10's. If you still can't decide then get the 3.90's, even though the difference between 3.90's and 4.10's is minimal so you might as well go with the 4.10's.

You could always be a badass and go with 4.56's and not use first gear anymore lol.

I am saying with 4.10s and a blower you will hit your rev limiter at 111 mph in 4th gear. When I went too the track I was using 18" saleen wheels with 265/35 profile and had no traction.

So - If you have a blower and going to the track it is a must to invest in drag radials otherwise your 60 foot suffer. These drag radials being a 28" tire would reduce your 4.10s lower for more miles per hour. If you are just going to be an occasional track person and not looking for drag radials then I recommend 3.73s period.

People make such a big freakin deal about the highway and gears. it is only a few hundred RPMs more. your not gonna even feel it at the pump. I know I dont.. I till fill up about every 2 weeks just like i did before with stock gears. were talking like MAYBE 2-3mpg loss..big deal

Gas mileage shouldnt be an issue if you drive like a normal human being, but what you have to keep in mind is what your future plans for the car is. If you pick too steep of a gear now and s/c the car later ,chances are that you will be running out of gear and end up swapping it out. It really depends what you want. Do you prefer acceleration vs top end? If you do run out of gear at the track you could always switch to a taller tire.
