Get more POWER from your Supercharged MINI Cooper 'S' with the effective and economical ULTRIK 3-piece pulley upgrade system with belt. A 15% reduction in the supercharger pulley diameter increases the boost by more than 4 pounds, resulting in a dyno-measured gain of over 20 horsepower AT THE WHEELS.
