There’s a certain irony that comes with listening to the engine of a Ford Mustang Shelby GT350. Most people will attribute it to noise, but for those who appreciate the roar of a 5.2-liter V-8 engine, hearing the Mustang Shelby GT350 get strapped up for a dyno test is music to the ears, the kind that soothes the automotive senses and relaxes the nerves.

Personally, that’s what I get whenever I see a video of a sports car or a muscle car undergoing a dyno test. I just close my eyes and let the cacophony of screams coming out of that engine fill my ears. It’s a very relaxing feeling, one that I’m sure fellow auto enthusiasts will understand. But, that’s not the only thing worth mentioning about this video of a Mustang GT350 doing a dyno run. Sure, the engine’s mighty roar - up to 8,200 rpm! - is a notable highlight, but there’s also another aspect that’s worth mentioning. During this dynamic chassis dyno test, Hennessey was able to bring out 482 horsepower and 407 pound-feet of torque from that V-8. That’s a fantastic number that’s made more impressive by the realization that the V-8 didn’t seem to even break a sweat in reaching that output.

Moving forward, expect Hennessey to roll out a new performance package for the Mustang Shelby GT350. If past kits are any indication, it’s reasonable to expect a number of options being made available. An HPE700 kit will most likely be on offer, as will an HP800. Maybe Hennessey blows the lid off of the Mustang Shelby GT350 and offer a four-digit power kit for the muscle car. Stay tuned for that one.

Kirby’s first exposure into the world of automobiles happened when he caught Knight Rider on television as a five-year old boy. David Hasselhoff didn’t leave much of an impression on him (that happened later on in Baywatch), but KITT certainly did. To this day, Kirby remains convinced that he will one day own a car with the same ‘spirit’ as the original KITT (not the 2008 monstrosity). He doesn't know when that will be, but until then, he’s committed to expressing his love for KITT, and all cars for that matter, here at TopSpeed.  Read More
