An underdrive pulley system for your Ford Mustang will increase engine horsepower and IMPROVE GAS MILEAGE by reducing the amount of power required to drive external engine accessories on your Ford Mustang. The alternator, power steering, water pump and air conditioner all rob horsepower from the engine. When you replace the factory-sized crank and accessory drive pulley on your Ford Mustang with a resized underdrive pulley, the accessories are slowed, resulting in more horsepower available to drive the rear wheels. Typically, an underdrive pulley will increase output for your Ford Mustang by 12-15 horsepower, resulting in quarter mile improvements of .2 to .25 seconds. In addition, mileage improvements of 2 to 3 mpg are typical.
LFP Underdrive pulleys will increase horsepower up to 16 RWHP, and increase mileage by 1 to 2 MPG. LFP Pulleys are manufactured from billet steel, exceeding factory quality and are the only Pulley system available on the market today that are SFI approved for all racing applications.
