The Eaton Twin Vortices Series™ or Eaton TVS™ is a patented supercharger design that features twin four-lobe rotors, twisted 160 degrees. By comparison, the original Eaton supercharger features three lobes twisted 60 degrees. The fourth lobe and added twist, when combined with redesigned air inlet and outlet ports, creates a smoother, more efficient flow of air into the engine. In addition to improved overall efficiency, the twin vortices Eaton Twin Vortices Series supercharger 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.
