Superchargers

The Eaton Twin Vortices Series or Eaton TVST is a patented supercharger design that features twin four-lobe rotors, twisted 160 degrees. For comparison, the original Eaton supercharger feature three lobes twisted 60 degrees. The fourth lobe and added twist, combined with redesigned air inlet and outlet ports, creates a smoother, more efficient flow of air into the engine. In addition to improve overall efficiency, Eaton Twin Vortices Series superchargers have improved noise and vibration characteristics as well.

As a result of these design changes engine manufacturers can use a smaller Eaton Twin Vortices Series supercharger to create the desired amount of boost. This provides under hood packaging advantages as well as weight savings.
