Unorthodox Racing 95-99 Pulley Review

The UDP (Underdrive Pulley) is an aftermarket replacement for the crankshaft pulley on the Maxima, which drives the accessory belts. The UDP replaces the stock crankshaft pulley with a smaller diameter and lighter weight unit which allows the engine to rev more easily. Unorthodox Racing has developed a pulley system which not only provides light weight but also operates in a very proper and well constructed manner.

RVM Racing - Nissan Maxima 1995-2002 Lightened Underdrive Crank Pulley

The Pulley is both Oversized to Under-Drive the stock accessory pulley?s and severely lightened for a maximum HP gain. This upgrade that has no downsides, no extra noise, no riding harshness, all you gain is Horsepower. Gains of 6-8 HP at the wheels can be easily measured on Normally Aspirated cars and as much as 7-16 HP at the wheels on Turbocharged Cars. Our Main Crankshaft Pulley?s are easily compatible with other manufacturers Power Steering and Air Conditioner Lightened Pulley Replacements as well.
