AXLE TECH PARAMETERS:

Torque (ft. lbs.)

First Gear Ratio

Rearend Gear Ratio

Efficiency Factor		x .90(due to frictional losses)



AXLE TECH RESULTS:

Calculated Torque (ft. lbs.)

A simple formula can be used to help you find the absolute maximum torque your car can put to the ground. To find the maximum torque, take the (Torque of your car) x (Your first gear) x (Your rear end gear ratio) x (90% efficiency).

For example, let’s say your race car has 600 ft. lbs. of torque, you have a powerglide transmission with a 1.86 first gear ratio, and you have a 4.88 gear in your rear end. When you put those numbers into the formula, you get the following:

Each axle should be able to handle all of the maximum torque your car can produce. That way it is practically impossible to break an axle because you have at least a 200% safety factor.

To achieve maximum performance you should use the smallest axle that will safely handle the torque your car produces.
