Alta Amp-Eng-520 Lightened Crank Pulley
The ALTA Performance lightened crank pulleys for
the MINI Cooper and is engineered to reduce rotating
mass, increasing horsepower and torque.
The ALTA Performance pulley achieves power and
performance by reducing the rotating mass of the crank assembly.
Made from 6061-T6 aluminum and weighing in at .9 lbs,
the ALTA pulley is more then 6.2 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 100 pounds of weight from your vehicle. The
ALTA Performance pulley will not wear out engine
bearings or the oil pump, will have no effect on your cars charging
system, and will not add any additional vibration or noise.
Choose one of the ALTA Performance over driven
crank pulleys and increase your boost levels at the same time. Our
2%, 3% and 4% pulleys will artificially increase your supercharger
size by 2%, 3% and 4% too!
If you have a 15% pulley on you MINI now, you can
add The ALTA Performance 2% over driven crank pulley
and make you 15% pulley perform like a 17% pulley.
