I need to know whether to invest in a new lighter axel for a go kart
Before I take the plunge, I'd like to get "some" kind of idea of the kinds of gains one can expect from this kind of change.
The conditions as I know Them.
the 5Hp engine achieves max torque at 5200-5400 RPM.
the motor is geared at 6:1 and the gearing from the motor to the rear axel
is 34/27.. for a combined gear ratio of 4.76:1.
The current rear axel weighs on the order of 4 Lbs, without tires.
what kind of RPM gains could one expect from reducing real axel weight
to 2 lbs?
Note: the different between first and last is somewhere on the order of 1-2 % of rear axel RPM.
