R53 17% Supercharger Pulley

CravenSpeed's supercharger pulleys are precisely machined to offer a specific reduction of the original equipment size on your MINI's supercharger, with this model providing a 17% reduction. This modification is widely accepted as a safe level of reduction for this particular supercharger. The pulley features smooth, form-fitting teeth that, while taking longer to machine, ensure a long lifespan and quiet operation for your belt, preventing it from being eaten or thrown off. For optimal performance and longevity, a slightly smaller belt is recommended, such as The Gates FleetRunner belt. This supercharger pulley is compatible with all supercharged MINI models from 2002-2006, specifically the Cooper S. It is important to note that this pulley will not fit JCW (John Cooper Works) models, as they come equipped with a similarly reduced size pulley from the factory.
