wow 700 hp is pretty impressive! but they fail to mention what was done to the motor to handle that power. i cant imagine they would even try to run that truck with stock internals...

 

The 5.4L Triton engine pumping furiously at the heart of the F-150 Eliminator is equipped with a sophisticated 2.2L twin-screw Kenne Bell supercharger, augmented with an air-to-water intercooler that keeps intake-charge temperature low, allowing for maximum boost.

For daily street duty, the standard pulley that makes 9 pounds of boost produces 485 hp and 434 lb-ft of torque, says Jim Bell of Kenne Bell. Of course, swap to a smaller pulley and the party really starts.

Not only that, Bell is/was working on an upgrade for a system that will push through even more air

 

yeah according to that they just added the supercharger like we all do. that KB is nice, but i sure as hell wouldnt want to be pushing 20 psi (or whatever it takes to get that 700 hp number) through a stock motor
