Unorthodox Racing 3 piece pulley kit Nissan 350Z
What is the result of evolution? Unorthodox Racing Ultra Street Sets. Our Ultra Street Sets build upon the success of our Ultra Street crank pulleys by adding our Ultra Accessory pulleys. Like our Ultra Street pulleys, Ultra Street Sets are 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 crank and accessory pulley are held to within .001". In addition to the numerous machining steps taken to ensure the crank pulley is the lightest possible design, each accessory pulley is also lighter than the factory piece it replaces and includes lightening holes where possible. Ultra Accessory pulleys are 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.
Unorthodox Racing pulley sets on average can provide gains of 8 to 15 HP and 6 to 10 lbs.-ft. on normally aspirated engines and 10 to 18 HP and 10 to 20 lbs.-ft. on forced induction engines. Higher gains can be realized on vehicles that are modified.
