Increase performance and reliability with the Alta Lightened Crank Pulley (LCP) for your supercharged MINI Cooper S. Offered in 0% stock size and +2% overdrive options, this billet aluminum pulley reduces rotating mass and can safely increase boost levels—resulting in improved horsepower, torque, and throttle response without affecting your charging system.
