What Is A Flat-Plane Crank V8?

You may have heard the term “Flat-Plane Crank” and have questions about its engineering on the Ford GT350 V8 engine.  The Flat-Plane Crankshaft engines not only sound different but also rev to incredible RPMs, and a lot more to learn about.

What Is A Flat-Plane Crank V8?

Through research, development and technology today, the V8 engine can be turned into a monster machine that roars like a lion and purrs like a kitten! Advancements in Ford engineering have made this engine possible and available to consumers.

V8 engines have a distinct and recognizable sound to most car enthusiasts.  The rumble burble sounds great!  To the discerning ear, the flat-plane crank V8 is a perfect virtuoso performance.  So other than the way the engine sounds, what makes it so sought after?

In order to achieve a balanced, light-weight and track-capable engine, Ford invested heavily into research and development.  The flat-plane allows engineers to program the ignition in a perfect alternation piston firing: left-right-left-right. It’s lighter crankshaft can quickly spin making it race-ready for RPMs up to 8,200!

Even exhaust gases are maximized for efficiency and better performance in the flat-plane crank 5.2L V8 of the GT350 when compared to a standard cross-crank V8 like the Mustang GT 5.0L, all thanks to a less complex manifold.

The GT350 is a new kind of Mustang. Track-ready from the factory, its V-8 makes 526 hp and some of the best 8200-rpm noises you’ll ever hear.  Watch as a drummer demonstrates the difference from a regular V8 to the flat-plane crank.
