zepherman · 03-24-2002, 06:34 PM

with a t-5, in 5th gear at 60mph what rpm will the motor be at with 2.73, 3.08, 3.55, and 3.73.

Thanks in advance fellas.

we need tire diameter as well

or you could just go to the analyzer page on here, put in your diameter and gear ratio and it will tell you the mph at each 100 rpm.

2.73: 1467
3.08: 1675
3.55: 1908
3.73: 2005

I got this with the analyzer here, i used a 25.5" tire height. you can go there and figure out rpm's in every gear with diff gear ratio's.

If your car is drivable NOW, then do the math yourself...

If you have 3.08's , then divide your current rpm by 3.08.
Then multiply that number by 3.55, or 3.73, or 4.10 ...
