Ford Shelby V8 for Shelby GT350 Mustang

Legend in the Making

You are looking at the most power-dense, most powerful naturally aspirated road going engine in Ford history. It’s also the Blue Oval’s highest-revving production V8 ever.

All to do with economy, of course.

Well, not quite. The word is efficiency.

The new 5.2 liter flat plane crank shaft V8 produces 392 kilowatts and 581 N.m. Specific output is over the magic 100 horsepower per liter of displacement, at 102 (76 kW) and it hits the red line at 8 250 r/min. It will be used in only two models, the Shelby GT350 Mustang and Shelby GT350R.

The objective of the Shelby GT350 programme was plain and simple: the most balanced, nimble and exhilarating production Mustang yet, according to Ford Performance chief engineer Jamal Hameedi.

The engine’s unique new aluminum engine block features Ford’s patented plasma transferred wire arc cylinder liner technology. This process eliminates typical heavy iron cylinder liners with a deposition process. A lightweight, high-capacity composite oil pan contains baffling designed for sustained high-speed corner­ing and hard braking. Ford’s announcement of the new engine makes liberal use of the term ’race’’… watch this space.

In both Shelby GT350 and Shelby GT350R, the all new 5.2-litre will be paired with a six-speed Tremec TR-3160 manual transmis­sion as its only gearbox option.

Flat = fast. Traditional cross-plane crankshaft V8 engines attach the piston-carrying connecting rods to the crankshaft at 90-degree intervals, creating a “cross” of counterweights when viewed down the axis of the crankshaft. In the all-new 5.2-litre, the connecting rods attach to the flat-plane crankshaft at aligned 180 degree intervals – creating what looks like a flat line of counterweights when viewed down the axis of the crankshaft.

The forged-steel flat-plane crankshaft is “gun drilled” to reduce total engine weight and to improve bay-to-bay cylinder breathing. Besides resulting in a crackling engine note not typical of a rambling American V8. The flat plane crankshaft helps improve cylinder exhaust-pulse separation by allowing a firing order that alternates ignition events between the V8’s two cylinder banks. Better breathing equals more power potential.
