3.92 diff / Type 9

Hello, I have a 3.92 diff, type 9 gearbox (from a 1.8 CVH Sierra), 1.8 zetec and 15" wheels.

Now, I know you can get different ratio diffs, how does my diff compare with the other ratios available in terms of overall top speed and accereration?

Does a higher ratio number on the diff mean a higher top speed or better acceleration?

Is there a handy spreadsheet so I can compare ratios?

Thanks
Keith.

Higher number means better acceleration / less top speed.

Try Gearcalc to play with ratios - http://www.locost7.info/gearcalc.php

3.92 - higher acceleration/lower top speed

3.62 - lower acceleration/higher top speed

the 3.9 diff sits nicely with the type 9...Plus, you can (if you want), change the 3.9 crownwheel to a the 3.6LSD...it's a direct replacement...
