Underdrive Pulleys in a Nutshell.
Pulleys are part of the accessory drive system on you engine. They provide power to the power steering pump, water pump, air conditioning compressor, and alternator. These are driven via the serpentine belt from the crank pulley.
Underdrive pulleys free up power in two ways:
1) Changing the rate accessories turn
2) Reducing rotating mass
The biggest gain we as Saturn drivers will see comes from number 2, reducing the rotating mass. There is a finite amount of power that an engine produces. This power has to do a number of things; turn the accessories (above), drive the car, turn itself far enough for the next combustion cycle to take place. By reducing the amount of power that goes into turning the accessories, you make more available to drive the car.
