FORD 5.4 32 VALVE DOHC MODULAR ENGINE

In 1999, Ford introduced the DOHC 4-valve 5.4 L in the Lincoln Navigator under the InTech moniker, making it the second engine to use this name. Ford later used versions of the DOHC 4-valve 5.4 L in the 2000 Ford Mustang SVT Cobra R, the Ford GT supercar, and the Ford Shelby GT500. The DOHC 4-valve 5.4 L was also used in the Ford Falcon line in Australia under the Boss moniker until 2010, when it was replaced by a locally developed, supercharged version of the 5.0 litre Modular V8.[citation needed] The SVT Cobra R version of the 5.4 L 4-valve V8 had several key differences from its Lincoln counterpart. While the iron block and forged steel crankshaft were sourced directly from the InTech 5.4 L, the Cobra R powerplant benefited from new, high-flow cylinder heads that were designed with features developed for Ford's "Rough Rider" off-road racing program, application specific camshafts with higher lift and more duration than other 4-valve Modular cams, forged I-beam connecting rods sourced from Carillo, forged pistons that provided a 9.6:1 compression ratio in conjunction with the 52 cc combustion chambers, and a unique high-flow "cross-ram" style aluminum intake manifold. The Cobra R was rated at 385 hp (287 kW) and 385 lb·ft (522 N·m) though chassis dynamometer results have shown these ratings to be conservative with unmodified Cobra Rs often producing nearly 380 hp (280 kW) at the rear wheels.[36] The Ford GT version of the 5.4 L is a highly specialized version of the Modular engine. It is an all-aluminum, dry-sump 5.4 L 4-valve DOHC with a Lysholm screw-type supercharger and showcases numerous technological features, such as dual fuel injectors per cylinder and oil squirters for the piston skirts, not found in other Ford Modular engines of the time. The GT 5.4 L benefits from an improved version of the high-flow 2000 Cobra R cylinder head and unique high-lift camshafts. The GT is rated at 550 hp (410 kW) and 500 lb·ft (678 N·m).The Shelby GT500 uses a 4-valve DOHC 5.4 L with an Eaton M122H Roots type supercharger and air-to-liquid intercooler.[38] The GT500 5.4 L shares its high-flow cylinder head castings with the Ford GT, with only minor machining differences, and shares camshafts with the 2003–2004 Ford Mustang SVT Cobra; which have less lift and duration than the Ford GT camshafts. The 2007–2010 GT500 engine used an iron engine block, while the 2011 GT500 5.4 L receives a new aluminum engine block, with Ford's first production application of their patented Plasma Transferred Wire Arc (PTWA) cylinder coating, eliminating the need for pressed in cylinder liners. The PTWA spray apparatus was co-developed by Ford and Flame-Spray Industries of Long Island, New York, for which they received the 2009 IPO National Inventors of the Year Award.[39] The 2011 GT500 engine weighs 102 lb (46 kg). less than the previous iron-block version, thanks in part to the lack of cast iron cylinder liners.[40] All of the 5.4 L 4-valve engines destined for use in SVT vehicles, such as the Ford GT and Shelby GT500, have been hand-built by technicians at Ford's Romeo, Michigan plant[WIKI]
