When you think of diesel engines, you naturally associate them with trucks, Semi trucks, pickups, and everything in between. You don’t think of Ford Mustangs. And surely you can’t imagine someone swapping a diesel engine into one. Or towing something with it. Will wonders never cease? Behold a diesel-swapped Mustang towing a boat. 

This Mustang Cummins mashup is called “Smokestang”

Someone plucked the 2.3-liter stomach pump found in this Mustang for some massive torque. And as a bonus, it can roll coal and do smokey burnouts, too. Owner Westin Champlin calls it “Smoke-Stang.” The 5.9-liter Cummins six-cylinder powers the oddball mashup.

The 1989 Dodge Heavy Duty trucks used Cummins engines. It has legendary torque, especially at the low end. If there is a downside, which really doesn’t matter in this case, is that its redline is at 3,000 rpm. So this is no screamer. 

How much horsepower does the Cummins Mustang mashup have?

While the 5.9-liter oil burner pumps out 230 hp stock, this one has a bit more. Even with the giant turbo hinting that there’s more, Champlin isn’t letting the cat out of the bag. But there could be up to 1.000 hp based on the burnouts. 

Naturally, hitching up a boat is now no sweat for a hopped-up Cummins. And it only gets better, or maybe more bizarre, to see it ripping across the pavement doing glorious burnouts. That, or rolling coal with the boat as an afterthought. It’s mayhem and symmetry in a weird collision of spooling turbos and billowing smoke. 

Why was this Cummins swap made?

So, what was the point of all of this? There is no point. It’s just foolishness combined with the curiosity of why anyone would do this. Should it have been akin to raking the sand and adjusting the rocks, just so? 

How does the Cummins stack up to the stock Mustang offerings?

But now for the downer. In spite of that big turbo and the obvious tweaking of the Cummins, the Mustang and diesel combo was only able to crack 13.2 seconds in the quarter mile. That looks to be 0.7 seconds better than the EcoBoost, and one second slower than the 5.0-liter V8 Mustang. 

Who cares? It’s the kind of hoon we enthusiasts love. And Champlin has numerous YouTube videos you can digest if you’re interested in learning more. So check them out.
