Show original supplier description
The Harrop HTV1320-LSJ is a high-performance Roots-type supercharger engineered as a direct bolt-on replacement for the factory Eaton M62 unit on GM's 2.0L LSJ engines. This supercharger system leverages Eaton's Twin Vortices Series™ (TVS™) technology, featuring patented four-lobe rotors and high-flow inlet/outlet ports to significantly enhance thermal efficiency. Designed for increased performance, the HTV1320-LSJ boosts volumetric flow from 1.0 to 1.3 liters per revolution. Its advanced rotor design and construction contribute to a greater volumetric efficiency, allowing the rotating group to flow more air per revolution and reducing internal restriction. This supercharger is specifically designed to fit the Chevrolet Cobalt SS from 2004-2007 and the Saturn Ion RedLine from 2004-2007. While it's a direct replacement, it's important to note that for optimal results, particularly on stock setups, modifications such as upgraded injectors may be necessary. Professional installation and tuning are recommended to maximize performance and ensure proper operation.
