BMW Drive Belts & V-Belts

Your BMW's drive belts are wear items, and will degrade and crack over time. Don't wait until you have a belt failure... don't get stranded! Replacing your BMW's belts, such as the alternator belt, power steering belt, air conditioning AC belt, or serpentine belt is a low cost insurance policy to preventing a break down -- or worse, engine damage. We recommend checking your belts every 10,000 miles. If your belts have excessive cracks, dry rot, missing teeth and/or grooves, are cause noise, it's time for new ones.

While also inspecting your serpentine belts, also check for wear or resistance in the pulleys. The tensioner pulley and deflection pulley are the primary sources for belt squealing. The rubber-isolated pulleys can also break apart, leading to total belt failure. We sell the tensioner and deflection pulleys for the M50 engine family used in the E34, E36, E39, E46, X5, Z3, and Z4.

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?

  • Excellent horsepower and torque gains - peak: 18whp/11wtq, max: 22whp/16wtq
  • Faster and smoother throttle response
  • Top speed limiter removed
  • Extremely easy to install/uninstall
  • Reversible and reusable
  • Elevated 8,250 RPM rev limiter
  • Compatible with 91 octane; 93 recommended

​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.

 

This item fits the following BMWs:
2001-2006 E46 BMW M3

M7 Speed 4% Oversize Crankshaft Pulley for MINI Cooper

Unlocking Performance

The M7 Speed 4% oversize crankshaft pulley is your ticket to unlocking the hidden potential of your MINI Cooper. This performance-enhancing pulley is designed to add power, acceleration, and overall performance to your beloved MINI. Here's how it does the trick:

Performance Boost:

  • Safely speeds up your supercharger, delivering a significant "low end" boost and torque.
  • The result? Your MINI Cooper takes off with newfound energy and responsiveness.

Lightweight Advantage:

  • Weighing just 13 ounces, this pulley is a remarkable 88.5% lighter than the factory version.
  • Reduced crankshaft rotational mass equals more horsepower, torque, and improved throttle response.

Advanced Design

The M7 Speed 4% Crank Pulley isn't just about performance; it's also a work of art. Crafted with advanced computer modeling and precision CNC machining, it's a blend of form and function:

Materials:

  • Made in the USA from billet 6061-T6 aerospace-grade aluminum alloy.
  • Features a deep black anodized coating and laser etching for a sleek look.

Precision Machining:

  • Micro V-Belt grooves meet SAE J1459 specifications to minimize belt slippage, especially at maximum boost.

Optimal Fit:

Use it in conjunction with the M7 Speed 16% Supercharger Technology Pulley for peak performance in MINI tuning.

Reliable Performance

From the factory, MINI lacks a positive drive key on the crankshaft snout to drive the lower pulley. Most aftermarket pulleys are slip-fit and rely on the bolt to prevent slippage. The M7 Speed crank pulley is engineered differently:

Interference Fit:

The pulley is interference-fit onto the crankshaft, ensuring zero slippage even at high RPMs.

Features at a Glance:

  • Super Lightweight: Only 13 ounces (0.3 kg)
  • Sheds 6.2 lbs (2.8 kg) compared to stock
  • Achieves perfect balance through a symmetric design and precision machining
  • Includes a high-quality ARP Racing bolt and precision ground flat washer
  • Installation is a breeze

Unleash Your MINI's Potential

Proudly made in the USA, the M7 Speed 4% Oversize Crankshaft Pulley is the upgrade your MINI Cooper deserves. Unleash its hidden power and enjoy a new level of performance, reliability, and overall driving pleasure. Get ready to experience the difference.
