BMW E46 Underdrive Power Pulleys

BMW E46 Underdrive Power Pulleys Reduce parasitic loss of power on your BMW's engine by safely under driving the belt driven auxiliary systems. Reducing this drag on your engine results in MORE HORSEPOWER AND TORQUE to the wheels of your BMW. Our BMW underdrive power pulley kits are specifically designed for each BMW application to make the best power while maintaining stock driveability and reliability, eliminating potential downsides. Others may advertise "their" pulleys boasting more power, but we concluded that for street and track driven BMWs, ours are the best size and design to ensure both your engine and it's belt-driven systems (alternator, water pump, power steering etc) are well within safe operation. We run these under drive pulleys on our own BMWs, so we would not want them any other way.

E46 M3 Power Package - Shark Injector, Power Pulleys, & IAT Relocation Kit

Shark Injector Performance Software
The enthusiast's choice for over a decade, the Shark Injector's performance is only equaled by its own ease of install! Tune your ECU at the press of a button simply by plugging into the under-dash OBDII diagnostic port, there is no removal of your car's computer; no laptop or cables required. What does the Shark offer?

  • Unlock torque and horsepower
  • Smoother engine with less hesitation
  • Improved throttle response
  • Rev limit increased to 8100 or 8600
  • Top speed limiter removed
  • Installs in minutes!
  • Advanced features optional - DSC button controls Sport mode (only one button to push) or Sport mode memory (car remembers you Sport mode preference even after shutting the car off).

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. 


Intake Air Temperature Relocation Kit
Looking to maximize your power gains? Add a Turner IAT Relocation to combat power-robbing heat soak - the only true plug-and-play solution available. Heat soak is a real plague on consistent power for a stock or tuned vehicle. Click here to read more about our IAT relocation kit.

2001-2006 E46 BMW M3

Part #: E46S54SIPULLEY
Price: $718.90 (USD) 
Free Shipping Free Shipping
Turner Motorsport Racing Pulley Set - E46 M3 TMS E46 M3 Racing Pulley is designed to achieve three goals: gain horsepower, reduce alternator and power steering pump wear, and lower power steering fluid temperatures. Due to constant high revolutions of the S54 power steering pump when on the track, we designed our racing power steering pulley to slow down the pump. This lowers fluid temperatures, resulting in less wear to the pump. This kit also includes a large alternator pulley, which also reduces wear. Kit uses our street water pump “under drive” pulley. All of these working together produce a significant gain of over 15 horsepower. The pulley has been track tested on our Grand Am Cup M3’s and dyno-tested. This is strictly for race/track cars only, due to the size of the alternator pulley the proper voltage cannot be maintained at low RPM.

Note: We sell pulleys separately incase you have special needs. Simply give us a call, or drop us an email.

Turner Motorsport Power Pulley Kit - E46 323i/328i 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! It's like FREE HORSEPOWER !

Underdrive pulleys for your BMW will slow down engine-mounted accessories - the water pump, power steering pump, and alternator*. These systems contribute to 'parasitic losses' - power lost from what the engine could produce if it did not have these systems. Since less energy is used to move them, that power is transferred back to the engine and used to propel the car. Our pulleys give a 10-20% reduction in rotation, releasing up to 11hp on most BMW six-cylinder engines. There's also a small but noticeable improvement in throttle response too! We have done extensive testing and development work, both on and off the track, to ensure that the accessory systems function as they should. On our Racing pulley kits we actually underdrive certain components more so we feel our Street pulleys are an ideal compromise between power/torque gains, reliability, and system performance. Our pulley kits have been on the market for over ten years, and used in all of our own cars, with zero component failures related to their use.

Our pulleys are made from T-6061 aluminum and finished in a durable black hard anodize that is very resistant to wear, chemical exposure, and heat. We designed our pulleys to look similar to the factory parts but also to be stronger and, in most cases, slightly lighter too. For example, a Turner alternator pulley is less than half the weight of the stock steel pulley! With our hardcoat aluminum you will never have to worry about a serious failure of a stock plastic pulley. A 'stealth' approach to aesthetics was our goal and we let the results speak for the pulley design. Installation is straight forward and easy with simple hand tools. Removal of the fan is required for access to the front of the engine. Total install time for a 3-piece pulley set should be around 1.5 hours. A new longer belt is included and we also recommend replacing the separate A/C belt, belt tensioners, and the guide and deflection pulleys at the same time.

* Alternator Pulley Options
Bosch or Valeo?  BMW built your car with either a Bosch or Valeo brand alternator. Unfortunately, the pulley is not the same for both brands. The brand is usually printed on the black plastic cover of the alternator but may be facing the frame rail or the ground. If you know which brand you have, select your option below and we'll send you the correct alternator pulley for your BMW. Don't know which you have? NO PROBLEM! We can send you both. The 2nd pulley costs $40 but you will receive a refund once we get the un-used pulley back (return shipping not included).

Stereo Systems. We offer our kits in two different ways: the full Power Pulley Kit with all 3 pulleys or a 2 pulley kit if you do not wish to underdrive your alternator (for large stereo systems or other battery-draining modifications). Our kits have been tested for compatability with the factory premium stereo systems (Harmon Kardon, etc). But any major alterations or upgrades from the factory system will work best with our 2 pulley kit and no underdriving of the alternator. For all stock stereo systems the 3 pulley set is recommended because the Turner alternator pulley will help make more power and is also much lighter than the stock pulley.

Turner Motorsport Race Alternator Pulley For E46 M3 Valeo Alternator

Part of the process of building a proper race car is to delete and simplify portions of the wiring harness. This not only saves weight and reduces complexity, but it also allows you to run a smaller, lighter racing battery. So why is your alternator still charging at the original rate?!? This S54 racing alternator pulley underdrives the alternator more than our standard Power Pulley, freeing up horsepower and reducing alternator wear. This pulley is over 70% larger than the original stock pulley. With less electrical load, you don't need the original alternator output anymore. You can drive the alternator less and return that "lost" horsepower back to the engine. This part was developed and race-proven on our E46 Touring Cars.

Because this pulley is so much larger than the original (70%), special care will need to be taken so that it does not interfere wtih other components on the engine - power steering lines, oil cooler lines, coolant hoses, etc. This pulley is strictly for race/track cars only, due to the size of the alternator pulley the proper voltage cannot be maintained at low RPM. This pulley must be used with our Turner Power Pulley or Turner Racing Pulley kits.

For the stock M3 Valeo alternator only.

Turner Motorsport Power Pulley Kit - E46 M3 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! It's like FREE HORSEPOWER !

Underdrive pulleys for your BMW will slow down engine-mounted accessories - the water pump, power steering pump, and alternator*. These systems contribute to 'parasitic losses' - power lost from what the engine could produce if it did not have these systems. Since less energy is used to move them, that power is transferred back to the engine and used to propel the car. Our pulleys give a 10-20% reduction in rotation, releasing 10hp on the E46 M3. There's also a small but noticeable improvement in throttle response too! We have done extensive testing and development work, both on and off the track, to ensure that the accessory systems function as they should. On our Racing pulley kits we actually underdrive certain components more so we feel our Street pulleys are an ideal compromise between power/torque gains, reliability, and system performance. Our pulley kits have been on the market for over ten years, and used in all of our own cars, with zero component failures related to their use.

Our pulleys are made from T-6061 aluminum and finished in a durable black hard anodize that is very resistant to wear, chemical exposure, and heat. We designed our pulleys to look similar to the factory parts but also to be stronger and, in most cases, slightly lighter too. For example, a Turner alternator pulley is less than half the weight of the stock steel pulley! With our hardcoat aluminum you will never have to worry about a serious failure of a stock plastic pulley. A 'stealth' approach to aesthetics was our goal and we let the results speak for the pulley design. Installation is straight forward and easy with simple hand tools. Removal of the fan is required for access to the front of the engine. Total install time for a 3-piece pulley set should be around 1.5 hours. A new longer belt is included and we also recommend replacing the separate A/C belt, belt tensioners, and the guide and deflection pulleys at the same time.

* Alternator Pulley Options
Stereo Systems. We offer our kits in two different ways: the full Power Pulley Kit with all 3 pulleys or a 2 pulley kit if you do not wish to underdrive your alternator (for large stereo systems or other battery-draining modifications). Our kits have been tested for compatability with the factory premium stereo systems (Harmon Kardon, etc). But any major alterations or upgrades from the factory system will work best with our 2 pulley kit and no underdriving of the alternator. For all stock stereo systems the 3 pulley set is recommended because the Turner alternator pulley will help make more power and is also much lighter than the stock pulley.
