Get Bruce Anderson's book 'porsche 911 performance handbook 2nd edition' from Amazon.

In the back he lists both ring and pinion types for the 930 tranny and all the corresponding gears that you can use and the speed each attains at different rpm levels (all on a couple graph charts).

I have the 5 to 1 gearing with the change to lower ring and pinion but everything else the same.

It is insane in 2-4th gear, but 1st gear is almost non-functional. I would change my first gear to about 50 mph if I could, it is like 42 mph now. Redlines instantly right now, too soon.

If you are serious about this, that book will be worth it for those two charts alone.
