Harrop has given the Ram 1500 utility the boost that it needed with the release of our TVS2650 Supercharger kit, which is built around the largest, most-efficient rotating group ever produced by Eaton. As a master distributor and technology partner of Eaton Supercharger and Traction products for over 12 years, Harrop has leveraged their OEM design and manufacturing capability to design a world leading system that is unrivaled in functionality and performance.

Harrop FDFI (Front Drive Front Inlet) TVS Supercharger systems feature industry leading Intercooler technology to ensure optimum thermal efficiency through advanced intercooler design. The Harrop cast aluminium manifold incorporates a large twin pass intercooler core that is located directly under the Supercharger discharge port to maximise Intercooler surface area. The unique intercooler system coupled with large front mount heat exchanger and high flow Bosch intercooler pump, provides greater thermal and volumetric efficiency to unleash the performance potential of the Hemi 5.7 V8 engine in both on-road and off-road situations.

The instantaneous boost response from the positive displacement Supercharger provides maximum torque from off idle and right the way through the rev range. Perfect for towing and any off-road adventures, the Harrop 2650 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. All Harrop Supercharger kits are expertly assembled by qualified Supercharger technicians to AS9100 quality standards, before individually tested in-house on a dynamometer to ensure reliability and durability.
