What size axles should
you be running to be sure that you will not break one?
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 racecar has 600ft.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:
600ft.lbs.
(torque) x 1.86
(first gear) x4.88
(rear gear) x.90
(efficiency) 4901 ft.lbs. of Torque
This is the maximum torque transmitted to
both rear axles if the tires have perfect
adhesion to the track, a and you launch the
car at its torque peak.
The torque rating of Moser Custo Alloy Axles
are as stated.
To achieve maximum
performance you should use teh smallest axle that will
saftely handle the torque your car produces
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
200% saftey factor.
