Does anyone know the exact science of picking gear ratios for maximum performance? I have a supercharger and was debating between 3.73, or the 4.10's. If i have to shift into 4th (in the quarter mile) with the 3.73's, then i might as well get the 4.10's right? One of the magazines had a formula based on peak dyno numbers to find the best ratio, just looking for some info.
Thanks
