Diff Ratios

Post Thu Sep 22, 2005 9:47 pm

I know its prob been asked a million times but do we have a sheet that lists gear,rpm and speed for each ratio of diff ?

If not i want to compile one.

thanks

no there isn't mate but people on here know what your getting at, but then u need to know gear ratios too, so u can see top speeds in each gear with different boxes and diffs! get me

good idea but beyond my brains!

If you want to do this for all E30s you will need different tables for the different gearboxes and wheel/tyre sizes.

I think http://www.e30.de has tables with all the ratios. Then you need the site posted by Andy335Touring to do the speed calculations.

A gearing limited top speed could be worked out but unless you take into account how much power each model has and you know out the CD of an E30 and can figure out how it will affect top speed then you won't be able to get an exact figure.
