930 Turbo Gearbox

[Rusti Evo]

Got the chance to buy a refreshed 930 Turbo 4 speed and was thinking about adding a Quaife ATB.

Seems to me for trackdays a really tough 4 speed would be ideal match for a torquey V8. Tall first and 180 max.

Any thoughts?

Bit of a git to get working though - have a word with Andygtt.

have a look at this thread on it:

How do you get 180 max?? 10 inch go cart wheels or 6000 revlimit??

Here, use this calculator. It's the stock 4.22 gearing.

I'll change to a 5.125 final and 2.00 first.

Sorry, didn't explain myself properly as usual!!! What I was hoping to get was a big first gear with a maximum of 180. Final to suit. Just don't see the need for a five speed gearbox.

Many thanks for the calculator - very useful.
