/// What is a TVS supercharger and why do you want one?

The Twin Vortices Series (TVS) is the 6th generation of Eaton Roots type supercharger. It features four lobes per rotor and specially designed inlet and outlet ports. TVS reaches pressure ratios as high as 2.5 with maximum thermodynamic efficiency no less than 75%. The Eaton TVS rotor group, is the same supercharger technology used in factory-supercharged GM, Audi, Jaguar, and Ford vehicles, and is the only supercharger technology that stands up to OEM durability and reliability tests.

The CT k-series supercharger kits use the older less efficient 3 lobe or 5th generation rotors. Additionally, the 1320 TVS displaces 1.32 liters vs. the CT’s M62 1.0L. This additional displacement allows more air to flow at the same blower speed when using the 1320 TVS.

The 1320 TVS is perfectly sized to the high flowing Honda K-series engines. This upgrade is for owners that want more from their supercharger kits, while still retaining the reliability and quick throttle response that the CT kits are known for.

These kits are only offered aftercooled or charge air cooled (CAC).
