Ford announced the most powerful naturally aspirated road-going engine in its history. The all-new Ford 5.2-liter flat-plane crankshaft V8 will produce 526 horsepower at 7,500 rpm and 429 lb.-ft. of torque at 4,750 rpm in Shelby GT350 Mustang and Shelby GT350R Mustang – an engine unique to the two models set to go on sale this fall.
In both Shelby GT350 and Shelby GT350R, the all-new 5.2-liter will be paired with a six-speed manual transmission as its only gearbox option. The Tremec TR-3160 six-speed manual is specifically engineered for less mass and high-rpm application in the new Shelby Mustangs. The six-speed features a lightweight, die-cast aluminum case and clutch housing for increased overall powertrain stiffness. Gear cross-sections, the dual-mass flywheel and dual-disc clutch are all optimized for an overall reduction in inertia and weight.
Other aspects of the new 5.2-liter V8 (actual displacement is 5,163 cubic centimeters) include a slightly oversquare bore and stroke of 94x93 millimeters, and a performance-enhancing 12.0:1 compression ratio. Computer numerical control-machined cylinder heads house camshafts that develop a massive 14 millimeters of lift for both the hollow-stem intake valves and sodium-filled exhaust valves. A single, fast-acting 87-millimeter throttle body – the largest ever used for a Ford engine – feeds air to the engine, allowing for a simpler, lighter intake.
Further reducing engine weight is a unique new aluminum engine block featuring Ford’s patented plasma transferred wire arc cylinder-liner technology. This process eliminates typical heavy iron cylinder liners with an electroplate coating. The forged-steel flat-plane crankshaft is “gun drilled” to reduce total engine weight and to improve bay-to-bay cylinder breathing. A lightweight, high-capacity composite oil pan contains baffling designed for sustained high-speed cornering and hard braking.
