MINI Convertible V2 17% Supercharger Pulley by ALTA Performance - R52 - Cooper S/JCW is the ultimate performance upgrade for your MINI Cooper S or JCW. This supercharger pulley is engineered to deliver an increase of over 20+ wheel horsepower, providing the power boost you've been seeking for your ride.

The ALTA Performance Supercharger Pulley is crafted from lightweight 6061T6 aluminum, which not only reduces the rotational inertia of the supercharger but also enhances the engine's response. The cross-drilled holes increase belt grip and drastically reduce belt slippage, ensuring consistent performance as your belt stretches. Furthermore, the oversized belt retainers safeguard against the belt jumping off, providing additional reliability.

The ALTA pulley uses a stainless steel clamp-on coupler method—an innovative approach that offers better grip over aftermarket alternatives, maintaining performance even on worn-down supercharger shafts, providing reliability and durability.
