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.
