how to figure out speed by the tach????
i run a stock geared t-5 , 25.8' tire, and 3.73 gears. can someone tell me approx. the speed would be at 5200 rpms? my speedometer is broke, ran a gsxr 600 and was killing him, that is where i let up at, just curious.

Trans gear ratio X Axel Ratio X MPH / Tire diameter X 336 = RPM's
I know your looking for Mph and that formual is for finding rpm but swtich a few things around and it should work. Hope it helps.
