Just wondering what the MY04's are running?

Thanks.

 

This is the info I've got:
F.D. is still 4.10:1
However, the secondary reduction gear out the back of the tranny has changed to make gears 1 to 4 "feel" like you've got 4.44's in the diff. They then went and made a slightly different 5th and 6th gear ratio so that the highway cruising rpm didn't change.

 

thx xviper...

 

Yup xviper is right final drive is still 4.10:1

For reference

Drive shaft ratio is...
2004 - 1.208
2000 - 2003 - 1.16

2004 Gear ratios
1st - 3.133
2nd - 2.045
3rd - 1.481
4th - 1.161
5th - 0.942
6th - 0.763
Reverse - 2.8

2000-2003 Gear ratios
1st - 3.133
2nd - 2.045
3rd - 1.481
4th - 1.161
5th - 0.971
6th - 0.811
Reverse - 2.8

 

thx guys...

I was wondering if I could benefit from a FD change via update/backdate clause in ASP for autocross. If the ratio is the same, then I need to look elsewhere.

 

Here are the final drive calculations for both years.
