Just Listen to the Growl of the Ford Mustang Shelby GT350R

Maybe your alarm clock malfunctioned this morning, and if that is indeed the case, we at Harbin Automotive are happy to help. As you almost certainly are already aware, the 2015 Ford Mustang is now available at our Alabama dealership, and we’ve had an absolute blast sharing it with the well-traveled masses in our area. And although we could certainly try to describe the sound that emerges from its flat-plane crank V8 found in the Mustang GT350R, we feel as though this video might do a better job of tackling that task. Scroll to the bottom of the page, and feel the fury of the Ford Mustang Shelby GT350R flat-plane crank exhaust, and reach in vain for a seat belt that is nowhere near your office desk chair.

When you listen to the video below, and consider that it’s the among the only of its kind in production today. Most V8s use what’s called a “cross-plane crank,” which is just what it sounds like–”cross-planes” form a cross shape when viewed from the end, while “flat-planes” form a straight line. Easy enough, right?

Well, not exactly. The impetus behind using a cross-plane design is the thought that won’t vibrate as much, since there’s a roughly equal amount of inertia heading in every direction at all times. A cross-plane gives off the familiar burble, spinning sound that V8s are famous for. However, since they are counter-weighted, they are also much, much heavier, and they aren’t able to be revved as high as the lighter, smaller flat-plane cranks. That’s why you can see the Mustand GT350R red-lining at about 8,000 rpms, which simply wouldn’t be possible with a cross-plane crank.

Well, that’s been a lot of explaining, when all that you really want to do is hear this baby hum. So, without further ado, here it is.
