Gearbox Transmission Ratio = Input Speed / Output Speed

**How fast is 70 rpm in mph?**

At 70 RPM, without additional information such as gear ratios or tire diameter, it’s impossible to calculate speed in mph.

**What is the relationship between rpm and speed?**

Speed reduction in a gearbox is calculated by comparing the input speed (from the engine) to the output speed (from the gearbox). The reduction ratio is typically provided in the gearbox specifications.

**Does a bigger pulley increase speed?**

Yes, using a bigger pulley on the input side and a smaller pulley on the output side of a belt-driven system will increase speed. This is due to the difference in the circumferences of the pulleys.

**Is higher or lower gear better for speed?**

Lower gears (numerically higher gear ratios) are better for achieving higher speeds because they provide more torque to the wheels. Higher gears are for lower speeds and improved fuel efficiency.

**What is a 7.0:1 gear ratio good for?**

A 7.0:1 gear ratio is relatively high and is typically found in applications where high torque is needed, such as in off-road vehicles, heavy-duty trucks, or specialized industrial equipment.

**How does gear ratio affect RPM?**

Gear ratio directly affects RPM. A lower gear ratio (higher numerically) will result in higher RPM for a given vehicle speed, while a higher gear ratio (lower numerically) will result in lower RPM.

**How can I increase my gear speed?**

To increase gear speed, you can change to a higher gear ratio. This is often done by upshifting in a manual transmission or by using an automatic transmission’s “overdrive” mode.

**How do you know the gear ratio without pulling the cover?**

You can estimate the gear ratio by counting the number of teeth on the ring gear (located on the differential) and the pinion gear (attached to the driveshaft). Divide the number of teeth on the ring gear by the number of teeth on the pinion gear to get the gear ratio.
