The R53 and R52S are true MINI classics – robust, responsive, and known for their unmistakable supercharger sound. With a smaller supercharger pulley, you can noticeably increase performance without making deep changes to the engine management system.
What are the benefits of a pulley upgrade?
- More power: The smaller pulley spins the supercharger faster, increasing boost pressure – resulting in around 20 additional horsepower and significantly stronger mid-range torque.
- Efficient and affordable: The pulley upgrade is one of the most effective performance improvements for the R53/R52S. Usually, the conversion with the correct belt and recommended spark plugs is sufficient – no chiptuning required.
- More torque: Earlier boost delivery makes the MINI feel more agile and responsive. With the same driving style, fuel efficiency can even improve slightly.
The pulley upgrade is a proven modification for more driving fun and performance without compromising reliability – ideal for anyone wanting to unlock the full potential of their supercharged MINI.
