Eaton manufactures highly engineered, roots-type positive displacement superchargers. The Eaton supercharger increases torque across the entire operating range without compromising drivability or emissions. Increasing supercharger torque allows vehicle manufacturers the option of using smaller, more economical 4- and 6-cylinder engines, without perceived loss in power train performance. Additionally, the supercharger incorporates a bypass system to reduce air handling losses when boost is not required, resulting in better fuel economy. Typical applications are on engines with displacements of 1.8L to 5.3L
