ScienceofSpeed manufactured pulleys are made for Autorotor based Comptech Supercharger Systems. The smaller pulleys allow increased pressure for additional performance when used with additional fueling and engine control components.
Horsepower increases up to 20-40 hp. Proper engine management is required (1991-94 NSX: AEM EMS recommended - 1995-2005 NSX: AEM F/IC recommended).
Pulleys are precision machined from lightweight 6061 aluminum and feature a special anodized black coating that prevents wear and increases belt traction.
Note that measurements are taken on the top of the pulley teeth (please see diagram) not on the face.
Pressure ratings depend on a variety of factors including supercharger system efficiency, displacement, and ambient air density.
