Free additional power to your e9x M3’s rear wheels without sacrificing or compromising your BMW’s reliability.
Machined from 6061-T6 aerospace aluminum, Macht Schnell Performance Underdrive Pulleys are strong as well as lightweight to limit parasitic drag from the accessories within a moderate level for maximum performance on or off the track. After machining and engraving, pulleys are then T3 hard anodized for additional strength, anti-corrosion & wear resistance.
Our DualDrive design replaces the Crank Accessory & Power Steering Pulleys, resulting in a 9-14 HP and 7-9ft. lbs TQ gain from reduction in power required to turn accessories and an increase in accessories lifespan due to lower speed. All factory harmonics/balancing are undisturbed.
Macht Schnell Performance Underdrive Pulleys have no negative effect on accessory operation and come fully equipped with new belts.
