By just adding the Unorthodox Racing Pulley Set to your Z your horsepower can jump to 10 to 15 more horse power with the performance pulley set. An Unorthodoxs Racing Pulley Set for the 350z will improve the horse power and torque performance. Unorthodox Racing was the first to develop Sport Compact power pulleys. Unorthodox Racing Pulley Set brought them to market in 1997 and today we remain the only source for cutting edge power pulleys. Unorthodox Racing pulleys are the lightest and best balanced and have the finest finish available. Unorthodox Racing pulleys are CAD designed and manufactured here in the USA to guarantee you unequaled performance, and a perfect fit with long lasting durability. Unorthodox Racing Pulley Set is CNC machined from lightweight 6061 T6 aluminum billet. Premium 6061 T6 aluminum billet ensures the consistency of the material's strength and balance. Tolerances for each accessory pulley are held to within .001". In addition to the numerous machining steps taken to ensure each Unorthodox Racing Pulley Set is lighter than the factory piece it replaces and includes lightening holes where possible. Unorthodox Racing Pulley Set is also an excellent replacement for the brittle plastic pulleys found on many late model cars. Premium fit and finish ensures a beautifully matched set you are proud to display under the hood of your vehicle. Even more critical with the addition of a supercharger, now you can have the same boost level with the use of the factory diameter crank pulley. Unorthodox Racing pulleys are one hundred percent of the power gains from the stock diameter pulleys come only from weight reduction versus the factory crank pulley. The reduced weight allows for more power transfer to the drive wheels. These are average gains. Power gains are obtained in two ways. First is the weight loss. An average of 4.7 HP is gained from every pound lost off the crank shaft. 85% of Unorthodox Racing gains are from weight loss. The rest of the gains are from under driving, which accounts for about 15% of the total gains. All of under driving 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. Unorthodox Racing pulley lightened under drive crank pulleys provide excellent power gains for little investment.
