Wondering if anyone can help me out
I have an MA gripper straight cut dog box
Finally got my car running, took it for a drive and it took all the teeth off 4th gear, these teeth have gone round the box damaging the pinion and final drive. The gearbox was previously in an 8v turbo and I'm guessing it was abused.
After a quick call to Dave Mac we found out it is repairable at a fairly reasonable cost but we also found out that the box has a 2.9:1 final drive which is apparently really long.
I was wondering if anyone know what final drive ratio I should be looking at?
The car revs to 8500, and will be almost entirely on circuits like, cadwell, brands, Donnington, Bedford (though I'm not too fussed about the gearing being a little short for the long straight at Bedford)
I don't seem to be able to find any info on the individual gear ratios if anyone knows them or can point me in the right direction?
