-Pulleys: Lightened pulleys increase horsepower by decreasing the parasitic effects that factory accessory pulleys have on a vehicle's engine. The pulley's lightweight reduces rotating weight and increases efficiency. All pulleys have a tooth profile that is guaranteed to match Original Equipment (O.E.) specifications, eliminating the chances of premature belt wear. Pulley sets on average can provide gains of 8 to 15 HP and 6 to 10 lbs.-ft. on normally aspirated engines and 10 to 18 HP and 10 to 20 lbs.-ft. on forced induction engines. Higher gains can be realized on vehicles that are modified.
