At Hennessey’s dyno, a 2016 Ford Mustang Cobra Jet put down 871 rear wheel horsepower.
We’re all quite familiar with the Dodge Demon, the world’s fastest accelerating road-legal production car and self-described king of the drag strip. The Demon is undoubtedly fast with 840 hp (with the right fuel and modifications) and a zero to sixty time of just 2.3 seconds on a well-prepped drag strip.
But even before the Demon rolled around for the 2018 model year, Ford had their own drag race monster for sale. It wasn’t road legal by any stretch of the imagination, and while the Demon could be comfortably driven at highway speeds as an everyday cruiser, Ford’s car was designed specifically to live its life a quarter-mile at a time.
Ford’s monster was named the Mustang Cobra Jet.
Its body and frame are still that of a Mustang, and the 5.0-L V8 under the hood also started life as a standard Mustang engine, but everything else has been replaced with gear specifically designed to win quarter-mile drag races.
The 6-speed manual has been tossed for a 3-speed automatic that tops out quickly for maximum acceleration. The rear independent suspension has been replaced by a 4-link version with adjustable coilovers and springs. The brakes have been replaced by lightweight Strange Engineering versions as well as a parachute. And the 5.0-L engine has been given a 2.9-L supercharger for an eye-watering 1,000 crank horsepower.
That’s a lot of horses. But how many does it retain through that 3-speed automatic transmission?
It turns out that most of those horses stay put. Hennessey’s dyno test reveals a rear-wheel horsepower of 871. That’s a loss of just 13%, which is often better than Hennessey’s 1,000 horsepower beasts.
We’re not sure what Hennessey was doing with a 2016 Ford Mustang Cobra Jet. It could be that they were simply performing maintenance for the owner, but the fact there was still plastic covering the bucket seats seems to indicate this Cobra Jet was brand new. Perhaps Hennessey is working on an even more ridiculous drag race monster than the Cobra Jet already is.
Could 2,000 horsepower be on the winds? We wouldn't put it past Hennessey.
