Eaton Corporation has unveiled its newest generation of Roots-type supercharger design that will enable automakers to use smaller, more efficient compressors to create more engine boost.
The new design, called Twin Vortices Series (TVS), features four-lobe rotors and high-flow inlet and outlet ports that greatly enhance thermal efficiency, enabling greater volumetric capacity at higher revolutions per minute (RPM). Previous Eaton Roots-type designs featured only three-lobe rotor assemblies. The new TVS supercharger design is scalable and adaptable to virtually all engine designs, according to Eaton.
We think the TVS is a game-changer that will allow our customers to make more horsepower without the traditional engineering tradeoffs. The TVS design has remarkably improved efficiencies and broadens the performance range of the supercharger across an engine’s entire performance range.—Jeff Romig, vice president and general manager of Eaton’s supercharger business
Eaton has development programs underway with several automakers to incorporate the TVS into future vehicle programs and it is working with its aftermarket partners to make the TVS technology available to performance enthusiast in 2007.
