Gear Ratio Calculator Rpm Mph
Not to be used in place of real testing.
Gear ratio calculator rpm mph. Calculate gear rpm mph tire diameter. Enter vehicle transmission gear. To find your vehicle s rpm enter your ring and pinion gear ratio tire height and speed and press solve. The same tire and rpm will give the following speeds based on the following gear ratio changes.
This calculation is used to match oversize tires with new ring and pinion gears to obtain the desired engine rpm at highway speed. Transmission gear ratio i e 2 54 1 43 1 00 etc tire diameter in inches 24 5 26 27 5 etc the speed in mph is miles per hour. Enter shift at rpm select gear to shift to and hit auto shift to run up through the gears recording shift point rpm and kph. Determine your engine s rpm based on the transmission gear ratio tire height mph and the ratio of your ring gear and pinion gear.
Enter vehicle rear gear ratio 3. This calculator is for entertainment value only. Enter vehicle tire diameter. Axle ratio x vehicle speed x transmission ratio x 336 13 tire diameter 3 73 x 65 x 1 00 x 336 13 31 2628.
Drag max rpm slider to adjust the range of the rpm and kph gauges. Use our calculator to determine the top speed and gear ratio for your tire size. For mini bikes 35mph is the top speed when using a torque converter. Enter vehicle rear gear ratio 2.
This calculator will provide the speed of the vehicle based on the transmission gear ratio the engine rpm the tire height and the ring gear and pinion gear ratio in the rear end axle differential housing.
