Twin Vortices Series
The Eaton Twin Vortices Series or Eaton TVST 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 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.
What Customers Are Saying
Eaton TVS superchargers first appeared in Australia on the TRD Aurion and then showed up at the 2007 SEMA show in Las Vegas on a Roush Mustang and recently GM announced it would utilize the Eaton Twin Vortices Series supercharger on the 2009 Corvette ZR1 and 2009 Cadillac CTS-V.
