I used to have an 01 GT 5 Speed and now I have an 00 GT 5 Speed.....

Here's my issue, I don't remember the 01 turning as high of RPMs as this 00.

at 62-65 MPH im turning like 2500 RPMs and at 70-72 MPH I'm at 3000... I can't find a calculater that can let me know what gears I have. this car pulls harder than the other 01 I had. How can I figure out what gears I have? Thanks guys

 

Your 01 may have had a 3650 and your 00 has a T-45. That would make the difference.

 

3grand at 70MPH??? sounds like 4.30's...someone will come along with the answer on how to see what gears you have though.

 

Wow I guess I didn't even really read the whole post Yeah that definitely isn't a stock gear. It is at least 4.10 or more.

Jack the car up in the rear and spin the wheel one revaluation and count how many times the driveshaft rotates.

 

Sounds like 4.30's....

 

I spun the tire it turned 1 time and the driveshaft rotated 4 times....

 

yep, sounds like a 4 something...

 

More than likely 4.11's, just a smign' more than 4 turns of the drive line to one turn of the wheel.

If you had 4.56's, you'd see about 4 1/2 turns of the drive line to one turn of the wheel.

If you had 3.73's, you'd see atad less than3 2/3turns of the drive line to one turn of the wheel.

 

I've got 4.10's and a t45 ...Not turning 3k @ 70 though....more like 2600...kinda why I figured it was 4.30's...

 

Ya. Sounds like 4.30's. I am not near that at 70 with my 4.10's
