Unorthordox Racing Under Drive Crank Pulley - $199.99 Shipped



Quote »Our most popular crank pulleys, the ones everyone is familiar with. This version of our crank pulleys increases performance because they underdrive all the accessories (15-20% more power), unlike accessory only kits out there that do not include the crank pulley. This means one you air conditioning is on our crank pulleys give you more power back to the wheels by not letting the air conditioning compressor rob as much power. However, we do not push the amount or percentage of underdrive too far 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. We always keep our underdrive percentage under 20% which is what allows us to maintain factory specified outputs for all your accessories. Our testing has found for most vehicle models you can upgrade your stereo to a system of up to 600 watts (RMS) and not have any charging problems. For most applications all of the underdriving is done at 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 realized. The Ultra Series underdrive crank pulleys are available in polished aluminum finish.
