526-Horsepower Ford Shelby GT350 Mustang Exceeds 100 Horsepower Per Liter with New 5.2-Liter Flat-Plane V8

At 102 horsepower per liter, the all-new 5.2-liter V8 for Shelby GT350 Mustang and Shelby GT350R Mustang is both the most power-dense and the most powerful naturally aspirated road-going engine in Ford history
·All-new Ford 5.2-liter flat-plane crankshaft V8 – an engine unique to Shelby GT350 and Shelby GT350R – produces 526 horsepower and 429 lb.-ft. of torque
With a redline of 8,250 rpm, the all-new 5.2-liter engine is the highest-revving production V8 in Ford history
Its crankshaft may be flat, but its power output is anything but “plane.”
Ford announced today 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 and 429 lb.-ft. of torque in Shelby GT350 Mustang and Shelby GT350R Mustang – an engine unique to the two models set to go on sale this fall.

“The Shelby GT350 program began with a clear objective – create the most balanced, nimble and exhilarating production Mustang yet,” said Jamal Hameedi, Ford Performance chief engineer. “Every change we made to this car was driven by the functional requirements of a powerful, responsive powerplant. The high-revving, naturally aspirated 5.2-liter flat-plane V8 delivers on every target we set – high horsepower, broad torque curve, aggressive throttle response and light weight.”

The all-new 5.2-liter V8 is not only Ford’s most powerful naturally aspirated engine ever, but also its most efficient in terms of specific output. Without turbocharging or supercharging, the flat-plane crankshaft V8 produces 102 horsepower per liter of displacement. The new engine is also the highest-revving V8 in Ford history – with a redline of 8,250 rpm.

Unlike traditional V8 engines, the all-new 5.2-liter uses a flat-plane crankshaft more typically found in a Ferrari sports car or in racing applications. The design of this new engine for the Shelby GT350 was optimized using computer-aided engineering and fully digital performance simulations. Millions of intake, cam and exhaust configurations were iterated before arriving at the optimal combination.

Better engine breathing delivers optimal power

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 Ford 5.2-liter V8, 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.
Beyond a change in the characteristic sound of an 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. This can vastly improve engine breathing, and subsequently allow the engine to make more power.

The result in the new 5.2-liter V8 – in addition to a uniquely exotic, delicious engine note – is 526 horsepower at 7,500 rpm and 429 lb.-ft. of torque at 4,750 rpm. Even more impressive is the track-tuned flexibility of the engine’s exceptionally wide powerband. It produces 90 percent of peak torque from approximately 3,450 rpm through 7,000 rpm, and features a racetrack-friendly spread of nearly 3,000 rpm between its torque and horsepower peaks.

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.

“A new Mustang as exceptional as the Shelby GT350 deserves an equally extraordinary engine,” said Dave Pericak, director, Ford Performance. “The all-new naturally aspirated 5.2-liter V8 perfectly fits the balanced dynamics of the Shelby GT350, and we believe this new engine will become a performance legend.”

It is amazing. I would kill for that in a Falcon.

As much as Miami is an awesome street engine Im yet to see/hear of any that can go prolonged distances on a circuit with corners. But to be fair it wasnt really designed for that.

This thing though..wow. Have they said if it will be available via Ford Racing?

[EDManual]

Waiting for someone to say , turbos make more power...

Would be such a buzz to drive! I want one!!

Hmm I'd rather they just bring the GT350 here rather than waste a gem of an engine in the Falcon (Miami evidence of that).

^^^It was more to swap out a 5.4 BOSS etc. Think the Falcon's goose is cooked mate..hehe

Turbos make more power

This seems very Honda-esque to me, revvy engine and mentioning hp per litre.

[Trek]

Do want!

Definitely prefer this over the SC V8 offered in the Falc

Turbos Wait until the VTEC kicks in.

[Polyal]

And what for those to say Honda now turbo's the VTEC anyway.

But who cares, this is a monster.

Ti-VCT yo

[mik]

looks good, i wonder how many of these engines they are expecting to put in road cars ?

[FPV GTHO]

I wonder how hard they'll be pushing these into racing. It has to share the spotlight with the Ecoboost V6 now after all.

[rancidpunx]

Come on Global Ford, get this sorted for RHD so we can enjoy it here without the need to go through a conversion company.

[Kayos]

Please bring it here, deposit waiting........

They can race Mustangs with this engine. The V6 EcoBoost won't be a Mustang race engine.

[FPV GTHO]

Previously though they only raced the 5L. Now they've got the 3.2 in USCC and either that or a modified 3.5 will be the WSC engine. Whatever Mustangs race won't be getting as much development anymore unless Ford intend to up their spending.

Yeah, and Ford is pulling out of pro drag racing.

But Mustangs should remain in GT racing, and maybe Ford will get more serious about that. The Coyote 5.0 was developed through Grand Am racing prior to its debut on the street.

Like it or not, V8s are going away. DTM will switch to turbo fours in 2017. V8 Supercars will likely drop "V8" within a few years. Drag racers and NASCAR may be the last V8 holdouts.

That soundtrack is to die for

May as well not have a stereo in the car, it will never be used.

New vid (GT350R)... Absolutely awesome!

I'd like to hear the cross plane engine. Yamaha have them in the R1 & they sound great, A V8 would sound hot

My prediction is that the next gen 3.5 V6 EcoBoost that will be in the 2017 F150 with 450 HP, will also be available in the Mustang at some point.

Give it a tune for more power.

A 'standard' V8 is a cross plane V8. This is a flat plane V8 with some tricky exhaust design to help it sound more like the cross plane V8 as a flat plane V8 generally sounds like a high revving 4 cylinder- as Ferrari V8s do.
