Wish Car and Driver would release some performance numbers for the GT 350.

Ford’s Voodoo V-8 Is the Most Interesting Engine of the Year


August 27, 2015 at 12:21 pm by Mike Sutton | Photography by Michael Simari and the Manufacturer

The new rev-happy 5.2-liter V-8 in the Mustang Shelby GT350 is one of the most compelling reasons to visit a Ford dealership in 2016. Code-named Voodoo and sharing its basic architecture with the Mustang GT’s 435-hp, 5.0-liter Coyote engine, this new powerplant is an altogether wilder animal, producing 526 horsepower at 7500 rpm and 429 pound-feet of torque at 4750. Camaro Z/28s, beware.
Voodoo harbors in its belly a flat-plane crankshaft with throws spaced every 180 degrees, like a four-cylinder—and also like a Ferrari V-8. The leaner crankshaft with lighter counterweights has lower rotating inertia than the 5.0-liter and provides evenly spaced exhaust pulses in each bank for better breathing.
Along with greater specific output, the result is a hellacious exhaust note unlike any other American V-8; the fury is Wagnerian as revs build to the 8250-rpm redline.
Ford sweated the 5.2’s components to shave a few pounds from the 5.0’s mass, and it will assemble the mills by hand at its Romeo, Michigan, engine plant. Its witchcraft V-8 will power the $49,995 GT350 and the $63,495 GT350R. Both prices include the Voodoo’s $1300 gas-guzzler tax.
Exhaust
Short-tube, 4-into-2-into-1 headers inflict minimal backpressure as they plumb the flat crank’s heartbeat into the GT350’s variable exhaust system. They also allow for closely mounted catalysts that improve cold-start emissions.
Intake

Long intake runners within the plastic manifold contribute to the engine’s broad power band, as do a gaping, 87-millimeter throttle body and a large-volume air filter.
Block
The reinforced aluminum block has the same bore spacing and deck height as the 5.0, but 94-by-93-millimeter bore-and-stroke dimensions yield 5163 cubic centimeters (or 315 cubic inches) of displacement. Voodoo’s larger bores necessitate plasma-transferred wire-arc cylinder surfaces instead of Coyote’s iron liners.
Heads
Ford optimized the aluminum 32-valve top end for high-rpm breathing and reduced mass. The hollow steel intake valves and sodium-filled exhaust valves are larger and more widely spaced than the 5.0’s, and are actuated by monster camshafts providing 14 millimeters of lift. Ford’s Ti-VCT variable valve timing helps manage the 12.0:1 compression ratio.
Fuel Delivery
Ford spared the expense and complication of direct injection for this low-volume engine.
Crankshaft
The 5.2’s connecting rods attach to the flat-plane crank at 180-degree intervals versus a normal V-8’s 90 degrees. A carefully tuned crankshaft damper helps manage the vibrations, and holes drilled throughout reduce weight. Both the crank and rods are made of forged steel; the pistons are constructed of forged aluminum.

I sure as hell find it to be the most interesting engine. Certainly the GT350 is the most interesting car in my budget hands down.

Ford could win again with turbo 6 GT next year. That thing sounded pretty damn wicked.
