Horsepower numbers are often a point of pride and bragging among car owners, especially those of us who love the Ford Mustang. After all, the Mustang has been around for nearly 50 years, and one of the most distinct things you can do to set your ‘Stang apart from the rest of the herd is to make more power than anyone else. The latest front in these inter-species horsepower wars is the “Coyote” 5.0, the latest addition to Ford’s engine arsenal.

Though the engine has only been on the streets for a year, many shops are already making impressive horsepower numbers. And Blow By Racing now claims it has the most powerful Coyote 5.0-powered Mustang in the world, with a recent dyno run of over 950 horsepower.

Actually they made 953 horsepower…not that they expected to make that much. In fact, the whole thing came together at the last moment. Chris Jones, Sales Manager of BBR, got in touch with Hellion about building a car for 5.0 Mustang’s annual King of the Street competition. Four days before the competition. And they built this car in four days.

Ok, to be honest much of the car was already put together, as BBR had previously equipped this Mustang with a supercharger system that boosted output to around 800 horsepower. What they did was remove the supercharger for a Hellion single-turbo setup using a Precision turbocharger, as well as adding a Nitrous Express 125 shot system to help spool up the oversized 82 mm turbo.

As it turns out, they my have spun the turbo a bit too high. Chris Jones tells us that they were running “around 35 pounds of boost” through the BOSS 302 intake manifold when it exploded, going through the hood of the car. This happened just days away from the competition, which meant repair the intake and the hood and starting over, running a much more managable 17-19 pounds of boost. On the dyno at their shop in Boca Rouge, Florida, the Mustang made approximately 830 horsepower. Good, but not record breaking.

However, the weather was much more agreeable at Holley Performance’s factory in Bowling Green, Kentucky. There Blow By Racing’s turbocharged Mustang laid down a monstrous 953 horsepower at the wheels with the temperature around 55 degrees and with zero humidity…plus the 125 shot of nitrous. That makes this the highest numbers yet recorded by a Coyote 5.0 Mustang, though even Chris Jones admits that there might be other cars out there making more power that never bothered to get it on the dyno. We say that is their loss.

Need more proof? The BBR Mustang shattered it’s drive shaft on it’s first attempt down the drag strip. So no ¼ mile times, and no dyno sheets either, at least for now.

That may raise a few eyebrows, we doubt BBR would be on the Corral.net forums making these claims if they weren’t true, and one need only wait for 5.0 Mustang magazine to release there official numbers to know if it is true. They plan to hit the track soon, and they promised to bring a video camera, so stay tuned.
