A lightweight pulley is the easiest and smartest way to free up horsepower on your import. By reducing the rotating mass on different parts of your engine such as the crank, power steering, air condition and more, you can free up anywhere from 1-2.7 HP per pound! Some stock crank pulleys weigh up to 13 pounds, while their replacement aluminum versions wiegh as little as 1.5 pounds freeing up tons of horsepower, but more importantly, allwoing your engine to rev up faster. This means you get through gears faster, which in turn gets you where you are going faster. Oure pulleys are made to gain most (85%) of their horsepower by reducing rotating mass, while the rest (15%) is done by slightly underdriving the accessories. This is the smart way to retain excellent streetability while gaining the most horsepower for your buck.
