Alta Lightened Crank Pulley – For MINI Cooper S R53/R52 Supercharged | SKU: AMP-ENG-500

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.

Key Features:

• Lightweight Construction: CNC-machined from 6061-T6 billet aluminum and weighs only 0.90 lbs—over 2.3 lbs lighter than stock.
