For 2007-12 GM 4.8L & 5.3L Trucks
TORRANCE, CA (August 16, 2012) - Edelbrock is excited to announce the release of the E-Force Supercharger system for 2007-12 GM trucks equipped with 4.8L or 5.3L LS engines. This system increased horsepower and torque gains on both engine configurations for improved street and towing performance.
In testing, a stock 5.3L was improved from 270 horsepower and 308 ft-lbs. of torque at the rear wheels, to 364 horsepower and 397 ft-lbs. of torque with the addition of the E-Force supercharger system. On a stock 4.8L truck, the performance was increased from 228 horsepower and 259 ft-lbs. of torque at the rear wheels, to 334 horsepower and 380 ft-lbs. of torque.
This new system utilizes the same Eaton Twin Vortices Series (TVS) Gen VI rotors found in the stock ZR-1 Corvette as well as Edelbrock's highly successful Corvette and Camaro Superchargers. Unlike other manufacturers, the supercharger assembly is integrated into Edelbrock's unique intake manifold for a truly seamless design with minimal components. The intake features 12" long runners for maximum low-end torque and an integrated bypass valve that helps reduce parasitic loss under light throttle for improved gas mileage potential. Keeping the air cool are dual, high capacity, air to water intercoolers and a full-face, low temperature heat exchanger. It has been designed to meet 50-State emissions and works with all OEM emissions equipment (E.O. Number Pending).
A Supplemental Fuel Pump kit will be required for all 2007-09 non-Flex Fuel vehicles. Two kits are available and they include a replacement fuel pump and fuel level sender.
