Your 2.2% diameter increase effectively turned your 3.7 into a 3.62. That is one concern about going to a bigger diameter tire. It will send the ratios in the wrong direction for tranny life. On the other side we have speedos that read too high so we don't want smaller diameter tires to exaggerate the problem more. I think they all read high because the spring loses its springiness over time. Plus, the odometer will rack up the miles faster for a smaller tire diameter. Bad for resale.....

Thanks, you are right about the formula, too many years past college. All I do is calculate area, and cubic displacement, so, I was stuck on auto pilot, and errored.
Yes, I effectively and purposely moved the gearing between 3.7 and 3.545. I do not believe this will have any effect on the life of the tranny, certainly less effect than the way I abuse it with my right foot
Either way, I like this side better than the other. My son and I built the tranny in the car now, and have done many others, so, that is not a huge problem.
I'm already running a hybrid cluster in this car, so, I'm familiar with the units. Where is the 'SPRING' you refer too? I have a couple spare gauge clusters, I'd like to check it out
