AMP Performance in Phoenix,...
AMP Performance in Phoenix, Arizona, gets credit not just for constructing the 830hp 5.4-liter, but also for the serious degree of fabrication. They had to merge what started off as a Hellion S197 Mustang GT turbo kit for a Three-Valve 4.6 to a Four-Valve 5.4! The single-blade throttle body is a BBK design for an F-150. It's round mouth makes it easier (compared with an oval twin-blade) to keep the inlet's silicone duct attached under boost. It all runs on a stock processor with Delta Force tuning software.
