I think you have that backwards... my top speed is reduced, I was below 3K at 65 in 5th before, and now Im at 3K. meaning I will hit my rev limiter prior to before.Originally posted by: pgtatx
The difference in the trannies is as follows:
Standard US Gearing:
1st: 3.417 (3.42)
2nd: 2.136 (2.14)
3rd: 1.483 (1.48)
4th: 1.114 (1.11)
5th: .854 (.85)
Acceleration off the line will be slowed and you'll be able to reach higher MPH in 1st, 3nd, and 3rd over the standard US trannies. Your top speed will be increased a tad.
1/4 mile times may be slowed a little however...could be the same though with that gear change in 3rd and 4th... But you should now be able to reach 60mph in second...

Actually, I'm not wrong...I should've clairified myself for you...
With the 3.8 final drive your 1st abd second gears specifically will be slowed. You'll pull to a higher MPH in these gears. It starts to even even off around 3rd and 4th gears going from the standard taller US gears to the shorter Euro ones.
If you had the 4.06 final drive or the 4.5, your top speed would be decreased as in my case (cut to near 120mph @ 7000rpm). Your top speed should be near the standard set up.
If you can do a test for me...run 2nd gear to the red line and see what the speedometer reads. Standard american Trannies should reach about 56mph, you should see around 60-65.
I had done all the calculations on these trannies to see what type of gearing I needed for my exact goals.
There are a few American Trannies with the euro gearing in them. I happen to have one. The difference is, mine came with the 4.06 final drive in it. Also since mine is not a production tranny, it does not have a standard part number. I replaced my final drive with the 4.5 anyway so it didn't matter.
But if you can run through 1st and 2nd gears for me, that'd be great, and mark the MPH at the RPM you reach.
So overall 1/4 mile times should be near the same...
Hope that clarifies it...
