• This Cummins-Powered Ford Mustang is the Most Ridiculous Car Ever

A Cummins-powered Mustang may be a Ford fan’s worst nightmare, but it does almost everything a diesel truck can, maybe even better

Apparently, a Ford Mustang can be the perfect car for towing a boat. Of course, this is only true after the appropriate modifications if you can call what Westin Champlin has done to this S550 Mustang appropriate. The YouTube DIY-er has done to the Mustang something that would make most Ford fans cry and impress most DIY-ers. The channel features a lot of epic creations, but this Cummins-swapped Mustang is, probably, in the top three craziest builds featured. A 1,000-horsepower Cummins in a Ford Mustang? What can go wrong?

Out of the box, the Ford Mustang S550 comes with either a 2.3-liter, turbocharged, EcoBoost, inline-four engine that makes 314 horsepower (231 kilowatts) and 318 pound-feet (432 Nm) or a 5.0-liter “Coyote” V-8 with 421 horsepower (313 kilowatts) and 390 pound-feet (529 Nm). Of course, the facelift model bumps those numbers up, but the one here is an earlier model.

This particular Pony car, apparently, started life as an EcoBoost Mustang with an automatic transmission. Being a pre-facelift model, we believe it has a six-speed automatic rather than the newer 10-speed, which Ford and Chevrolet co-developed. As for the engine, the stock, inline-four was, apparently, deemed insufficient for the YouTuber’s boat-towing aspirations. For this reason, a Cummins diesel unit was thrown in. It also has a big, single turbo sticking out of where the hood normally is. Really, the giant snail looks like Doctor Strange’s third eye at the end of the second movie and it’s just hilarious.

No, It’s Not a Shelby GT500 Diesel but it Looks Like It

Another absurd feature that we love about Westin Champlin’s Cummins-swapped Mustang is the top-mounted exhaust that spreads black clouds and cancer like a tanker on fire. Given the channel’s history with unusual and crazy builds as well as the “redneck science” approach to, well, everything, we expect the DIY-er to perform some dark magic on the coal-burning Pony car. Aside from the lack of a front hood, the Mustang features a GT500 front fascia, which makes things that much crazier.

Even in its stock form, the EcoBoost Mustang is quick enough for most people, with the 0 to 60 mph (97 km/h) sprint taking 5.5 seconds, and with later variants being even quicker. I am sure you have many questions regarding the build such as what modifications have been done to the engine bay or has the DIY-er modified the chassis so it doesn’t get spaghettified under the massive torque of the turbocharged diesel? While we are sure Westin Champlin would love to tell you all about it, feel free to see whether the Cummins Mustang is any good at towing boats and doing burnouts with a boat attached to its back.
