Unorthodox Racing Pulley Sets are available in a number of configurations.
Standard Belt Layout (Underdrive)
Our pulley sets provide most of the power gains through weight loss (80-85%). The remaining part of the gains from these pulleys comes from underdriving of all the accessories (15-20%).
However, we do not push underdriving for two main reasons. First, it is important to keep charging systems, air conditioning, power steering, and water pumps moving fast enough for every day driving. Second, not much horsepower is gained from extreme underdriving.
In most applications all of our underdriving is done with the crank pulley, not the accessory pulleys. This is done so maximum weight loss can be achieved at the crank where most of the horsepower gains are found.
Standard Belt Layout (Stock Diameter)
As with our stock diameter crank pulleys many of our customers have also asked for stock diameter pulley sets that do not underdrive their alternators, power steering pumps, superchargers and water pumps. Because of these requests we developed our stock diameter pulley sets. Many customers want the performance benefits of weight reduction without any sacrifices, especially audio enthusiasts as some audio competitions require voltage to remain at a specific level. With our stock diameter pulley sets the alternator and other accessories spin at stock speeds with NO underdrive. This is also important for stock or aftermarket supercharger systems. These systems are either driven off the alternator, air conditioning or power steering sections of the crank pulley and now you can use our stock diameter pulley sets with these supercharger systems and have the same boost you had with the factory crank pulley.st level with the use of the factory diameter crank pulley.
100% of the power gains from the stock pulley sets comes only from weight reduction versus the factory crank pulley. The reduced weight allows for more power transfer to the drive wheels.
