Overview

The CravenSpeed Supercharger Pulley is an aluminum pulley designed to increase boost and improve acceleration for MINI Cooper R53 models from 2001 to 2006. This pulley offers a 15% reduction, spinning the supercharger faster to generate more boost. It is made in the USA and features smooth, form-fitting teeth to protect your belt and ensure quiet operation.
Show original supplier description
This pulley features a 15% reduction compared to the factory unit, which directly translates to increased boost pressure from the supercharger. This boost increase leads to more horsepower and torque, providing a noticeable improvement in acceleration and overall engine responsiveness. Machined to precise specifications, this supercharger pulley is crafted for durability and optimal performance. The installation process involves replacing the stock supercharger pulley with this performance-oriented version. This pulley is specifically noted to work on all supercharged MINI models, excluding the JCW models which may already feature a reduced-size pulley. It is compatible with the MINI Cooper R53 models from 2001 to 2006 and the R52 Convertible models.
