fast.
The ALTA Performance™ lightened crank pulley for the MINI Cooper S R56 and Clubman S R55 is designed to reduce rotating mass, increasing throttle response and acceleration.
Made from 6061T6
aluminum and weighing in at .65 lbs,the ALTA pulley™ is more then 3
lbs lighter then the stock crank pulley. The ALTA pulley is not under
driven and will not affect the life of your engine. The pulley is a
redesigned, lighter rendering of the stock crank pulley.
The reduction in weight is effectively the same power increase as
removing 75 pounds of weight from your vehicle. The ALTA Performance™
pulley will not wear out engine bearings or the oil pump, and will not
add any additional vibration or noise.
Aftermarket, under driven, pulleys are prone to charging and
drivability problems from being excessively underdriven. The ALTA
Performance™ lightened crank pulley will have no effect on your cars
charging system.
