hwat is your RPM @70 mph? i put a turbo II tranny on my 84 gslse and the SE and turbo II dont have too much difference on gears but at 70 mph i get 2600 rpm. i just wanted to know just in case i have to calibrate the speedo. thanks

 

sounds about right. mines at 3grand about 80 or 75ish

 

The gear ratio in the rear diff as well as the tire size can change your RPMs at give road speed.

 

In what gear?

 

5th gear

 

:

 

in 5th gear i hit about 3grand around 80.

 

I'm dead on 3k at 80mph, but running numbers with stock rear tire size, stock ring and pinion ratio, and stock 5th gear ratio would suggest that either the tach or speedo really isn't correct at that point.

 

im on stock mesh S5 rims

 

in 5th gear according to the safc i'm hitting 3000 rpm at 80mph. according to the stock tach its about 3100rpm

 

3K + or minus 200 RPM...........was around 80 MPH

 

hmm... i think mine is actually about 70mph at 3K. ??
