BMW Superchargers

MINI R52 R53 Performance Polyurethane Super Charger Belt Damper Bushings are designed to enhance the performance of your MINI. These bushings transmit forces from the engine drive belt to the body, ensuring the hydraulic tensioner maintains optimal belt tension. Unlike OEM rubber bushings, which prioritize comfort and allow excess movement, Powerflex polyurethane bushings are firmer, reducing tensioner side-to-side movement and enhancing functionality. Key benefits include:

• Firmer than OEM rubber bushings for improved tensioner performance
• Reduces tensioner side-to-side movement
• Durable polyurethane construction for long-lasting performance
• Enhances overall driving experience
• Ideal for street use and occasional track or autocross
• Recommended use of Powerflex Copper Grease PCG1 for installation
• Lifetime warranty for the original purchaser

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.
