MINI Hardtop (3-door) V2 17% Supercharger Pulley by ALTA Performance - R53 - Cooper S/JCW

Turn your MINI Cooper S into a road-going rocket with the MINI Hardtop V2 17% Supercharger Pulley from ALTA Performance. This precision-engineered component is specifically designed to boost your vehicle’s horsepower while maximizing performance, making it a dynamic addition to the MINI Cooper S R53. Detailed in design, this supercharger pulley is your answer to immediate and robust power gains.

Designed from lightweight, high-strength 6061T6 aluminum, the pulley is engineered to minimize rotational inertia, which enhances engine response. Its innovative cross-drilled holes over each groove increase belt grip and reduce slippage, adapting to natural belt wear over time. The oversized belt retainers included in the design further support the elimination of belt failure. What sets the ALTA pulley apart is its stainless-steel clamp-on coupler, a pivotal feature that guarantees superior grip on the supercharger shaft without the risk of damage, even on previously compromised shafts.
