Edelbrock is excited to begin shipping the highly anticipated E-Force Supercharger system for 2014 GM trucks. The all-new design increases the stock GM EcoTec engine up to 528 rear wheel horsepower and 496 ft-lbs. of torque for improved towing performance. This E-Force supercharger incorporates the Eaton® Gen VI 2300 Twin Vortices Series (TVS) rotor assembly, as well as an air to water twin intercooler system and dual core heat exchanger.
