Key Features

The instantaneous boost response from the positive displacement Supercharger provides maximum torque from idle and right the way through the rev range. Perfect for towing and any off-road adventures, the Harrop TVS Supercharger gives sportscar acceleration in the comfort of a sports utility. Drivability is enhanced by the integrated bypass valve that dramatically reduces drag (parasitic loss) from the Supercharger rotating group and this also means better fuel consumption in “off boost” everyday driving.
