Hi guys,
Free additional power to your M5/M6’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.
MS's DualDrive design replaces the Crank Accessory & Power Steering Pulleys, resulting in a 18-20 HP and 16-20ft. lbs TQ gain for the M5/M6 and a 9-14 HP and 7-9ft. lbs TQ gain for the M3 (for M3 owners lurking). Gains are due to a reduction in power required to turn accessories; an increase in accessories lifespan due to lower speed will also result. 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.
MS Pulley M5/M6: $295
kits for E9X M3 also available for any lurkers.
Please feel free to contact myself, nerwyll@trinityautosport, or joe@trinityautosport for any inquiries and/or orders.
Thank you!
