How much horsepower will a ProStart handle?
A. The ProStart performance is dependent on torque rather than horsepower. Torque is roughly equal to horsepower. The ProStart is available in two models. A ProStart model is available for ’98-’07 Big Twins with stock or slightly higher torque (up to 90 ft-lbs of torque). For customers with modified engines or trike applications, the ProStart-HP model is available (up to 130 ft-lbs of torque).
