Description
Underdrive power pulleys for your BMW, Dyno-tested and engineered for a perfect fit.
Part number pp.e46
**This page is for pulleys to fit all E46 6 cylinder models (not M3). Please see Variations section (use red link button to the right) for all other models:
- E36
- E39 & M5
- E60 & M5
- E63 & M6
- E92 M3
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.
Estimated Installation Cost at Crest Workshops : £130.00 inc. VAT
Estimated Volumetric Shipping Weight : 4.00 Kg
