Every time the cylinders fire, torque is transferred into the crankshaft. The crankshaft deflects under this torque, which sets up vibrations when the torque is released. At certain engine speeds the torque imparted by the cylinders are in synch with the vibrations in the crankshaft, which results in a phenomenon called resonance This resonance causes stress beyond what the crankshaft can withstand, resulting in crankshaft failure. The accessory pulley acts as a balancer and prevents these vibrations from destroying your crankshaft.

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.

If you vibration damper is failing, it will usually present itself in the form of a squealing noise that sounds like a slipping belt. This is an indication that the rubber ring inside of the vibration damper has dried out and cracked, causing the pulley to slip.
