ratios for a 8v manual:
1rst= 3.91
2cnd=2.17
3rd=1.37
4rth=1.00
5th=.78
As you can see, a stock 8v has an overdrive 5th and 4rth is a 1.oo ratio.
The 16v ratios below are closer and 5th is 1.00 which is much better for not losing revs.
16v
1rst=4.075
2cnd=2.518
3rd=1.766
4rth=1.263
5th=1.00
The stock 8v trans totally sucks for track use!Too big a spread (especially) between 2cnd & third!
I put a 16v trans in every 190 racecar I build, but they are not easy to find and not cheap.
I have been looking into eventually having some "adapter" plate made so that I can maybe use a hi-perf 6 speed or even a custom dogring race tranny installed behind my 16v motor,,,,,,,,,,,,, when I eventually build my "killer" motor,,,, that is.
I'm sure it can be done, as I just recently bought a complete adapter kit to mount a porsche 915 trans axle to a rover v8, for my McLaren project I'm doing.
The kit came with a block to trans plate, a flywheel, hardware & instructions.
The place is "Kennedy Engineering" in California..... I bet If I sent them a bare block & the trans I want to fit it to, they could make the kit,,,,,,,,but like all "one off" custome work,,,,,,, it won't be cheap
