TVS Supercharger
The TVS Supercharger is an automotive supercharger that was developed by Eaton Corporation to improve on all existing types of superchargers. The TVS acronym stands for Twin Vortices Series.
It is a Roots-type positive displacement compressor. This new blower features twin four-lobe rotors which are twisted 160 degrees. This new design of supercharger is said to reduce noise, vibration, and harshness (NVH) compared to other designs. It made its first production car appearance on the TRD Aurion and it is currently used on Corvette ZR1, Cadillac CTS-V, supercharged Toyota Tundra, Lotus Evora S, Range Rover 5.0 litre V8, all "R" badged Jaguar vehicles, the Roush Stage 3 Mustang, and the Audi B8 S4,[1][2] which uses a 3.0 litre TFSI V6 engine. This engine with the same TVS blower is also scheduled to be fitted to a new hybrid version of the Volkswagen Touareg.[3] In the latest Shelby Mustang GT 500, which mounts a TVS supercharger, the power output is 662 hp. One of the key advantages of a TVS supercharger over older designs is a lower temperature of the compressed air on the outlet side of the supercharger. This allows for higher boost without intercooling to prevent excessive Intake Air Temperature (IAT) which happens with earlier designs.
