Lightweight Crank Pulleys reduce parasitic drag placed on the crankshaft by under-driving the accessories such as Alternator, Power Steering and Air Conditioning. Under-driving slows down the accessories to use less energy from the crankshaft but doesn't slow them down to the point the accessory operation becomes effected.
