Alta Performance BMW Superchargers for MINI

Enhance your Mini's performance with the ALTA Supercharger Pulley, crafted from lightweight 6061T6 aluminum. This pulley reduces the rotational inertia of the supercharger, significantly enhancing engine responsiveness. Featuring cross-drilled holes over each groove, it improves belt grip and minimizes belt slippage as the belt stretches. Additionally, oversized belt retainers prevent belt jumping.

ALTA offers two reduction sizes: 15% and 17%, each providing distinct benefits.

• 15% Reduction: The standard choice in the market, delivering smooth power increases of approximately 20WHP for safe performance enhancements.
• 17% Reduction: Ideal for those seeking more power, this option builds boost at lower RPMs, providing additional power where needed. It delivers an extra 1.5psi of boost at redline, ensuring added horsepower to conquer challenging situations.

Upgrade your Mini's supercharger with the Supercharger Pulley Belt from Alta Performance. Specifically designed for the R52 R53 W11 1.6L Engine and compatible with Alta 15% and 17% pulleys (part number 60535), this belt ensures optimal performance. Don't let a worn-out belt cause annoying squeaks under the hood – replace it every 30,000 miles and keep your Mini running smoothly.
