07 Gt500 Rear gear Ratio

[prison90]

I bought the car around 2 years ago and still trying to sort some of the mods out . I am not sure what the final drive is I thought it might be 3;73 but I am not so sure anymore . 1st and 2nd gear go by so fast dont really watch what the speed is when hitting 6000 rpm but in 3rd it hits redline at around a 100mph . I am thinkng maybe 4;10 gears know but could not find any RPM charts to help. Thanks for any help

Why not pull the cover and see what's stamped on the gears? Gives you a chance to inspect everything while you're in there.

The 3.31’s definitely gotta go. Been running 3.73’s for 10 years. Love mine at the track, would prefer 3.55’s for the street.

Thanks for correcting me @IronTerp .......sorry about that fellas. I agree with the 3.55's being better for the street

Thanks for the help . I finally found a gear calculator on the internet , they are 3.73 gears . I live in the midwest so there ok for out here . If i was back out west where speed limit is 85 MPH like Utah they would be tough on the wallet there.

If you’re going to be doing a lot of highway driving, just remember that the .63 6th gear in your tranny ain’t going to be much fun if cruising at high speed. Ask me how I know. Lol

3.73 is a great gear for that car IMO. 4.10 would be a tad too much on the early 500's.

I ran 80mph all the time. 13 MPG wasn't too bad.

 

[prison90]

I am still getting around 18 MPG at 75 MPH . 13 MPG at 80 ouch.

13 was total around town in mixed driving, and I have a HEAVY foot.
