Of all the Ford Mustang Shelby GT350’s selling points, including the R’s carbon fiber wheels, its the naturally-aspirated flat-plane crank V8 engine that’s caused enthusiasts to drool en masse around the world.
Revving to 8,250 rpm and delivering 526 hp, this bespoke powertrain emits a bark unlike any other combining the howl of Italian flat-plane V8s with the bellow of classic American muscle.
Despite how impressive the engine is, tuners have already began tampering with it in the never-ending pursuit of power. The latest to do so is Lethal Performance.
The company has outfitted the 5.2-liter V8 with a 2.9-liter Whipple supercharger that lifts power to over 800 hp and 600 lb-ft of torque.
Filmed here on the dyno, the completed system is undeniably impressive. But as you’d expect, the whine of the supercharger drowns out much of the V8 concerto.
Is the extra power worth it?
