This pulley has better than OEM belt fitment and alignment. Real world gains in horsepower, torque and fuel economy.This pulley is the perfect pulley for you daily driver street/strip car, the light weight will increase horsepower and torque by reducing the weight of the rotating assembly, without the problems associated with underdrive pulleys! Underdrive pulleys create a myriad of problems, starting with discharged batteries and overheating. By "underdriving" (making them rotate slower) the engine driven accessories you loose the capacity of the water pump and of the alternator to work where the manufacturer intended them to work, thereby creating overheating and charging problems. YOU WILL NOT HAVE THESE ISSUES WITH THIS PULLEY!! As this pulley is the same size as the OEM pulley, so all the accessories move and operate like the manufacturer intended them to. The other issue you will avoid is that you can use your stock sized belts, there are no new belts to buy, and if a belt breaks, you just go to your nearest auto parts store and get the factory one! These pulleys also have the OEM timing marks, which most underdrive pulleys do not, so you can easily check or change your timing.
