The quickest and easiest way to add 20+ Wheel HP to your MINI Cooper S!
Constructed of light weight 6061T6 aluminum, the ALTA SC pulley body decreases rotational inertia of the supercharger adding response to your engine.
Holes are cross drilled through the pulley and over each groove, to increase belt grip and reduce belt slippage as your belt stretches. Also incorporated into the design are oversized belt retainers, which reduces belts from jumping off.
The ALTA Performance Supercharger pulley features a stainless steel coupler which clamps onto the supercharger shaft rather then wedging in place like other aftermarket pulleys. ALTA was the first pulley to use this clamp-on method, and it has proven to grip the supercharger shaft better than other aftermarket pulleys and it will work for those who have had other pulleys slip and cause damage to the supercharger shaft. Our hub will attach to supercharger shafts that have been worn down as much as .020" and still work perfect!
Additionally the ALTA coupler features an open installation site aperture in end of our shaft coupler which allows you to visibly verify that the shaft collar is fully seated to the supercharger shaft.
This reduction size is the market standard and produces smooth, safe power increases of around 20WHP.
