​Turner Motorsport Power Pulleys 
Underdrive Power Pulleys work to 'free up' horsepower. Any accessory that spins from the main drive belt is using up power. That's power that could otherwise be used to move the car. By giving some of that power back to the engine, you can make the car faster! We measured 10.7 whp at 6960 rpm and 8.1 lb-ft of torque at 5550 on a 1995 M3. Race pulleys deliver even more power. 

Another "no-downside" upgrade, we even include a new belt. Total install time for a 3-piece pulley set should be around 1.5 hours. We offer three options in pulleys:
1.) No alternator pulley included - for cars with big amps and powerful stereo systems that need the extra juice.
2.) Street Power Pulleys - our most popular option with no downside!
3.) Race Power Pulleys - delivering 15 "free" horsepower, this set underdrives the water pump, power steering pulley, and alternator for lower temps, less wear, and more power. Not for street use.

aFe Power's new power pulley brings performance engineering to your BMW M5. This power pulley is a complete bolt-on kit, including the pulley, bolts, and belts. aFe’s power pulleys are CNC machined out of billet aluminum and black anodized for that aggressive look under the M5’s hood. This power pulley does not modify factory harmonics or dampening. In recent Dyno testing this power pulley produced 5 HP and 6lbs. x ft. torque. When it comes to engineering for power, performance, protection and value, aFe Power is the only choice. 

This part fits the following BMWs:
2006 - 2010 E60 M5
