With the Unorthodox Racing stock diameter crank pulley for the 2009+ Nissan 370z, the alternator and other accessories spin at stock speeds with NO underdrive. The benefit is the reduced weight vs the stock pulley. This allows the engine to rev up faster and smoother. 100% of the power gains from the stock diameter pulleys comes only from weight reduction versus the factory crank pulley. The reduced weight allows for more power transfer to the drive wheels. The stock diameter crank pulleys are available in polished finish only.
Features:
* The first stock diameter crank pulleys available for import applications (First introduced in 2000)
* Real HP & torque gains across entire RPM range
* One of the highest HP/Torque per dollar gains on the market
* Over 8 years of use in real world applications from street to strip to rally to road course
* Better than OEM belt fitment & alignment
* Accessory pulleys available separately for many applications
* CAD designed & CNC'd from 6061 Aluminum billet
