Engine RPM CalculatorEnter your axle gear ratio, tire diameter, vehicle speed, and transmission gear ratio in the blue fields and click the calculate button to find your engine RPM. Axle Gear Ratio: : 1 Tire Diameter: Inches Vehicle Speed: MPH Transmission Ratio: : 1 Engine Speed: RPM ...
Enter your speed in the field Vehicle speed. The RPM calculator will give you your 3rd gear drivetrain transmission ratio in the field Drivetrain transmission ratio (= 3.99). Notice that this is a ratio between two rotational speeds; thus, it does not have a unit. The calculator also gives...
The five speed option is for the last gear of a transmission greater than four speeds. The second calculator allows you to actually input any EXACT transmission final gear ratio. The higher the RGP ratio, the lower the top end speed but faster acceleration and more pulling power. The same ...
this info will only approximate your corrected speed and depends on the accuracy of tire size diameters (assumimg nothing but tire size has changed). If you know specific information about your vehicle (gear ratios, RPM, etc.) then use the Gear Ratio calculator, it's probably a little more...
The spec sheet you linked to lists the engine power at 7500 rpm and specifies a "custom" gear reduction of 1.5:1, so assuming the engine is operated at peak power: ---> 7500/1.5 = 5000 rpm prop speed As far as stability goes, I'm not sure if the prop rotation will be sufficient...
The result is a screamer, but one that has surprisingly good torque at normal traffic speeds. That's the beauty of VTEC, and you can see it in the good top-gear acceleration times, which are also helped by a fairly short final-drive ratio. The more-flexible power delivered by the moder...
