ACTIVE AUTOWERKE POWER PULLEY KIT - E46 M3

2001-2002 MZ3 Z3 M Roadster / Z3 M Coupe (S54 engine) 6 Speed and SMG

COME PLAY WITH POWER...

We are all infatuated with power in our own way. If you are looking on how to gain tremendous, additional horsepower for your BMW E46 M3 with the S54 engine, then there's the Active Autowerke supercharger yielding up to 650 horses.
If you are looking for something that is induced through normal aspirations, then there's the Active Autowerke performance tuned software or the Active Autowerke performance exhaust header all producing good horses as well. Then there's the BMW E46 M3 Power Pulley Kit. It looks more non-intrusive to the engine bay, it is easy to install, and it makes power.
Best of all, it is a good start to build on since it is modular in design and complements all other Active Autowerke BMW performance upgrades for the BMW E46 M3. The exception would be the Active Autowerke supercharger system which utilizes a dedicated 8 RIB pulley drive.

PURPOSE

The BMW S54 engine produces horsepower, however, all of this power is not fully achieved when the engine also has to drive other components such as air conditioning and power steering.

These ancillary components are driven by the engine crankshaft via a belt drive, but they all inherently take away some horsepower just to be driven. We refer to this as parasitic losses. To help reduce this drag, Active Autowerke calculated and re-engineered the pulley dimensions that would reduce these power losses on your BMW motor. The finished product not only achieved this but it still maintained that level of reliability and efficiency.

What is redesigned is the water pump, alternator and power steering pulleys. What is not touched is the engine crankshaft pulley. By not altering the harmonic of the engine crankshaft, the engineers here at Active Autowerke wanted to achieve this through a redesign of just the auxiliary drives.
The end result is the unleashing of untapped power on the engine. An additional 10 rear wheel horsepower gain as measured on the in house Active Autowerke Mustang dyno.

R&D DEVELOPMENT

When Active Autowerke designs, test and produces a supercharger system for the E46 M3 to produce over 650 horsepower, part of this design entails working on the supercharger belt drive. This includes calculating the right pulley diameters, groove pitch, belt alignment through pulley offsets, maintaining proper belt tension, and then continuous testing on the chassis dyno with our BMW E46 M3. Active Autowerke take this same approach applying into the design and development of the BMW E46 M3 Power Pulley KIT.
This is part of the building block concept where what is learned today is applied tomorrow. This is something that we do on a daily basis everyday.

Isolate harmonics before they can destroy your engine.

If your engine build is plagued with broken crankshafts and oil pumps, the cause may be a mystery to you as it has been to many. Controlling the harmonic resonance of the BMW 6 is highly important as RPMs rise, but the ideal configuration of the inline-6 motor makes even experienced engine builders overlook some fundamental principals of engine harmonics that can be destructive.

The truth is, harmonics can destroy these motors despite their ideal balance.
ATI Performance Products, a leader in Harmonic Dampers has developed two new dampers (Part # 917994 & 917994TR) for the popular S54 & S50b32 Euro, as well as the 3 liter S50b30 Euro.

These dampers are made available exclusively through VAC, and they nearly eliminate all unstable crankshaft harmonic-vibration, allowing the engine to produce more horsepower and torque, maintain reliability, and reducing internal engine wear at the same time.

A trigger wheel comes standard on M3 Damper (Part # 917994TR) needed for M3 euro engines.

When used with the included pulley, they allow a direct replacement fit over the OEM balancer. Available in underdriven , overdriven or standard diameters . Also, configurations available for use with our dry sump kits. Both dampers have a 7" outer diameter and include OEM style timing alignment tabs.

• ATI Super Dampers exceed SFI 18.1 Safety Certification and are approved for competition
•Made in USA
•Eliminate problems with inline 6s fitted with lightweight clutch and flywheel assemblies
•Control destructive harmonic forces
•Reduces instances of bearing wear, accessory failure and oil pump failure
•Includes lightweight VAC Billet Crankshaft Pulley (not shown)
ATI Performance Products, Inc. is located in Baltimore, MD, and specializes in producing and maintaining high performance products for street and strip applications. Over the years ATI has earned a reputation for its cutting edge technology, attention to detail and rigorous testing under race conditions. We are proud to have them as an exclusive partner in these BMW applications.

Light weight crank pulley.

These are NOT an underdrive pulley but rather a light weight version of thE OEM crankshaft pulley/ harmonic balancer, the advantages are typically :

- weighing approximately 20% less tha factory
- increasing throttle response and power
- does not separate / fail the way the factory pulleys are known to do, especially under hard use

Constructed with hard anodized 7075-T6 aluminium or tempered steel, depending which engine application.

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.
