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.
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.
