Excel Spreadsheet - RPMs - Gear Ratios
I have seen in several posts and at this moment can't find the calculation for determining RPMs with the inputs being the rear end gear (in this case 3.73s) and the ratios for the transmission (new TKO 500) -
1st 3.27 2nd 1.98 3rd 1.34 4th 1.00 5th 0.68 looking to run 20x8.5 - 255/40/20's - can anyone point me at that excel doc so I can plug these numbers in and see what things are going to look like. Thanks in advance. -W
