Description
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 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. 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

Performance Underdrive Pulleys Features:
- DualDrive design allows maximum performance, with minor affect on accessory speed
- Proper cooling temperatures are retained at proper levels on or off the track
- Maintains proper alternator speed, allowing sustained levels to sensitive control modules
- Machined from 6061-T6 aerospace aluminum
- T3 Hard-Anodized for maximum strength and corrosion/wear resistance
- No affects to crankshaft dampening or harmonics
- Simple bolt-on installation

Fits all models listed below:

- 2006-2010 E60 M5
- 2006-2010 E63 M6
(19.00.012 SOP-07 ~ 19.00.013 08-09)

ABOUT POWER PULLEYS

By gearing down the fluid resistance accessories (water pump, power steering), less engine power is diverted to spinning the pumps, thereby allowing your engine to spool up more quickly and produce more overall power.

Kit includes replacement water pump pulley, power steering pump pulley and new serpentine belt.

No detrimental effect whatsoever to your car's cooling and steering system, as by about 5000 revs the pumps are already working at their maximum capacities.

Whereas some other aftermarket pulley kits also include a replacement alternator pulley, we do not subscribe to this method of reduction. By reducing the alternator's ability to provide adequate voltage to the system, you may encounter electrical issues or system shortfalls not covered by the manufactures warranty.

On most modern BMWs, the crank pulley does more than just drive the accessories (water pump, A/C compressor, power steering pump, and alternator), it acts as a harmonic balancer for the crankshaft of the motor. When you remove this weighted, balanced component from the front of the motor and replace with a lightened, underdriven crank pulley, you can accelerate internal engine component wear since the crank is no longer weighted on this end.

Some companies offer just a crank pulley, which when underdriven, will then underdrive ALL of the associated accessories. This can lead to serious engine damage.

Each Rogue Engineering Power Pulley kit comes complete with installation manual and high quality replacement serpentine belt.

Application Notes

1. E36 328 models require last 7 digits of VIN in order to supply the correct power steering pulley. Include VIN with your order please.

2.Any power pulley kit which does include a replacement crankshaft pulley allow for the factory harmonic balancer to remain in place.

3.E39 M5 tensioner pulley requires minor modification of the factory tensioner bracket for installation. E39 M5 pulley kit also includes replacement A/C belt.

4.E60 M5/E63 M6 includes overdriven alternator pulley, which compensates for the underdriven crank pulley.

5.E46 M3 RACE pulley kit includes underdriven alternator and crank pulley. This pulley kit is STRICTLY for dedicated track/race cars (not cars that see street duty). A/C is no longer used. This is the same kit used on the Grand-Am Automatic Racing M3s. The crank pulley has been designed to accept a dry-sump cog. The STREET and RACE kit use the same size belt.


Fitting Time: 2.30 hours.
