Maximum boost produced by the supercharger is around 16 pounds per square inch. No changes are made to the stock throttlebody or radiator thermostat and installation would not require any modification to any fuel or emission related tubing. Supercharger is designed to be a direct bolt-on replacement to the stock supercharger. The Whipple Pulley Kits, part numbers WIK-5.4L-4VPGT and WIK-5.4L-4VPGT500, utilize the stock supercharger and include a different size supercharger pulley, 105mm mass air flow sensor, new ECM calibration, and a new open element air filter with intake air tubing.
