Body Design

The pulley body is machined from lightweight 6061 T6 aluminum to reduce rotational inertia for quicker supercharger response. Cross drilled holes through each groove improve belt grip and help reduce slip as the belt stretches, while oversized belt retainers help keep the belt securely in place under load.

Clamp On Shaft Coupler

Unlike wedge style pulleys, the ALTA design uses a stainless steel clamp on coupler for a secure, reliable hold on the supercharger shaft. This proven system grips better than traditional designs and even works on shafts worn up to .020 inch. An open inspection aperture allows you to visually confirm proper installation.

Precision Balanced

The outer pulley is machined from solid billet aluminum for natural balance. The hub adapter is precision balanced during production to ensure smooth operation at high RPM, meeting or exceeding factory balance standards.

Available in Two Sizes

The ALTA Supercharger Pulley is available in 15% and 17% reductions. The 15% option delivers smooth, reliable gains of around 20 wheel horsepower, while the 17% builds boost sooner and adds approximately 1.5 psi at redline for stronger low and top end power.

Supercharger Pulley Removal Tool

Installation Tool Available

An optional ALTA Pulley Removal Tool is available to safely remove the factory pulley on MINI Cooper S models, making installation straightforward and repeatable.
