Ford Super Duty Diesel Dyno Run Goes Off with a Bang
There may be no sound to go with this Reddit clip, but none is needed when the sight of an exploding Super Duty says it all.
There’s nothing like finding out how much power your upgrades have given to your Ford truck than with a visit to the dyno. Once everything’s tied down, you let ‘er rip on the rollers for a minute or so, bring ‘er back down, then collect the results from the run.
Sometimes, though, things can get out of hand. Redditor tszdabee posted a clip of a Ford Super Duty rolling coal hard on a dyno run before it all goes up in a big blaze of glory.
While most of the Redditors were busting on the participants going for an up-close-and-personal look at the wrecked Super Duty only seconds after it blew up, 0-100 simply wanted to know what happened. Luckily, a product development engineer from an unnamed diesel engine builder had his answer.
“This isn’t a runaway diesel engine, They are dyno testing it to find its max Hp/Tq number,” says Jsteele2012. “The large amounts of black smoke are due to extremely rich combustion conditions (lots of extra diesel being squirted in to try and make the most power).”
The Redditor adds that the white bottle on the ground next to the Super Duty was a bottle of nitrous, which was used to give more oxygen to the air-fuel mix. The explosion, meanwhile, was either the result of a line to the nitrous popping off on its own, or being knocked off via a connecting rod exiting from the block.
We hope this Super Duty will be back on the road, but we’d definitely wait until the fire is out and the dyno is stopped before having a peek at the damage done.
