Dyno,
Thanks for all the higher math.

. This was going to be my next step.
But let me clarify again the objective. I don't really care about the speedo accuracy. What got me started on this is the realization that I have gone through my upgrades and I am killing performance by having the equivalent of a
2.90 some odd rear gear. So the real purpose of this exercise is to at come up w gearing that approximates the performance of the stock setup. If the speedo is off, I honestly couldn't care.
The other objective of the thread is to give Ron fun.
