Default Top Speed With Gears.......

With 3.75 gears, what would be my top speed? I have a 2000 GT with 17" wheels and auto tranny

you mean 3.73 and your top speed will be faster than anything you'll ever be driving at, even at the track.

About 152 with your stock tires, trans, and engine. With 3.90 (or 3.9something) your top speed will be 149. With 4:10 it will be 132.


The funny thing is that you won't be driving those speeds too long at all, never. You might goof off once in a while, but usually highway speeds are 90 mph, 120 if you're in a hurry.

Thats not even close. Ask Jdaniel how fast he got his 4.10's GT to. It was 150+. Dont believe those little gear calculators on the internet. Just ask some people here and they will give you real world experience.

Are you just trying to top out or what??? You should be able to break 150 (even though that's really stupid). If I remember correctly (it was a loooong time ago) I htink Jdaniel said he hit 152 with his GT and 4.10's.....

bryan...look around on the forums....there are TONS of arguments about 3.73 and 4.10 gears. from what ive heard, i would go with 4.10s. the acceleration ill be better, and your gas mileage will still only drop maybe 2 mpg from stock from what i understand. i think with 4.10s youd be at about 3000 rpms going 90 i heard somewhere. but seriosuly, check around the forums, especially check out the sticky in the 4.6 section of the forums.

my $0.02 is for 4.10s tho.
