Eaton’s new Twin Vortices Series (TVS) is a Roots-type supercharger for a variety of engine applications that delivers more power and better fuel economy in a smaller package, for uncompromising, high-performance driving.
The TVS supercharger’s patented design features four-lobe rotors and high-flow inlet and outlet ports that greatly enhance thermal efficiency, deliver higher volumetric capacity, and enable higher operating speeds. The TVS supercharger is capable of running with a high thermal efficiency (up to 76 percent) across a very wide operating range.
The improvements incorporated into the TVS design allow for the use of a smaller supercharger, reducing the package size and weight of the system. The sizes range from 350cc to 2300cc per revolution, and cover engines from 0.6 liter up to large displacement V-engines. All TVS superchargers have a 2.4 pressure ratio capability and a thermal efficiency that exceeds 70 percent, which enables more compact packaging and greater output.
The twin four-lobe rotors feature 160-degree twists. The higher helix angle of the rotors coupled with a redesigned inlet and outlet ports, improves the TVS’s air-handling characteristics without increasing the overall size of the unit. The TVS improved noise and vibration characteristics eliminate additional noise-reduction treatments, complexity and system cost.
The TVS Roots supercharger sets a new standard of boosting device performance and reaffirms Eaton’s leadership in the performance automotive market.
