Performance
The ALTA Performance lightened crank pulley is engineered to increase horsepower and torque. Aftermarket under driven pulleys are prone to charging and drivability problems from being excessively under driven. The ALTA Performance lightened crank pulley will have no effect on your cars charging system. The 0% Stock Sized pulley is a lighter rendering of the stock crank pulley which will not wear out engine bearings or the oil pump, and will not add any additional vibration or noise. The 2% Over-sized has all the same features of the 0% Stock Sized pulley but adds more boost to your car (on Super-Charged Cooper S models only.) By simply increasing the diameter of the pulley boost is increased, safely and reliably.Construction
Made from 6061T6 aluminum and weighing in at .65 lbs,the ALTA pulley is more then 2.3lbs lighter then the stock crank pulley. The reduction in weight is effectively the same power increase as removing 60 pounds of weight from your vehicle.Two Sizes to Choose From
The ALTA crank Pulley comes in two sizes. 0% and +2% over-sized. The +2% overdrive effective shrinks your supercharger pulley size by the same amount. A 15% supercharger pulley will act like a 17%. A 17% pulley will act like a 19%.Compatibility
