Hello all! I have looked all over the internet for a formula that will tell me what rear gear is ideal to hit a specific rpm in the 1/4 mile, with no luck. I had my car dyno'd, and I know that the hp peaks around 5400 rpms. Correct me if I'm wrong, but ideally you want to be at (or just past) your peak hp rpm at the end of the 1/4 mile right? IS there a formula to figure out what gear will put you at a desired rpm or are there too many variables to do that?
