Supercharger Performance and Engine Performance Parts

This is the first in a series of ’snapshots’ of a manufacturer’s superchargers that I plan on posting every so often. As you can see it’s written in simple English (in horsepower and boost) and is an easy way for people that don’t know how to read a compressor map to get a good idea of what their supercharger (or planned supercharger) is capable of.

Eaton’s first supercharger was released on the thunderbird back in 1989. Since then, Eaton has blessed the market with 5 generations of positive displacement, roots style superchargers with incremental changes between every generation and the previous.

 “The fifth generation Eaton supercharger or Gen V is the culmination of over 50 years of improvement to the original design for Roots superchargers. It features two three-lobe rotors, twisted 60 degrees and provides engine manufacturers with a proven, economical solution for adding power.”

After five successful generations of the M-Model supercharger. Eaton released a new version of their positive displacement supercharger called the TVS – Twin Vortices Series.

“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.”

Figures in red are estimates based on relative supercharger displacement.
