    http://www.rivayamaha.com/RivaStore/...and%20impeller

    Our high performance impeller & housing combo deliver a significant increase in boost pressure and horsepower due through increased impeller blade surface area and larger interior housing volume. Produces 10.5lbs of boost at 8,400RPM when run with our recommended Stage III components. Impeller features a sophisticated Vortech blade design that is precision balanced to deliver smooth operation. Housing and impeller install easily onto stock supercharger base plate with no additinoal modifications required. Includes all necessary mounting hardware and installation instructions.

    That seems quite good considering the $$$.

    Its an awesome supercharger. Closest you can get to a B kit or Rude Charger without spending nearly 2 grand.
