Hi
The dif I have bought seams to have a differant ratio to many
alot of people are fitting IE 3.89:1 Dif

The one I have seams to have
9 teeth in the Pinion
and 33 on the Crown

This should give better acelaration is that right

Any one know what the Diff I have got is likly to be from

[Edited on 15/5/11 by Trollyjack]

English ratios were normally

9/40=4.44
8/33=4.125
9/35=3.89
9/34=3.77
11/39=3.54

I've been looking for a 3.54 for my 1300 xflow locost...
But all I've got is a 4.125.

Are you sure it's definately a ford english diff, 3.67 is not a ratio I've heard of?

A 3.67 will give less acceleration and a higher top speed than a 3.89

8 pinnion
33 Crown wheel

Only planning on using it as a Trackday Car

4.125 - should give good acceleration
