Our Underdrive Series of pulley sets provide power gains through weight loss and through the underdriving of all the accessories (which accounts for about 15% additional gain). 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. REady to ship now . Polished only. !! Gold Priceing !!
