How it Works

In addition to delivering power to the wheels, an engine must power several accessories, such as the alternator, power steering pump, and the air conditioning compressor. Unfortunately, these accessories require power to function, leaving less power to drive the wheels.  The Rogue Engineering underdrive crank pulley reduces the drag caused by these accessories while letting them remain at their peak efficiency.  The more accessories being underdriven, the greater the power increase. Therefore, BMW's benefit greatly from pulley upgrades because their engines run several accessories.
