WhistlinDiesel has built a jet-engine-swapped FedEx truck, hoping it would perform ‘same-minute delivery’.
Cody Detwiler, known online as WhistlinDiesel, is renowned for his ambitious car projects.
But as we’ve seen time and time again, these projects come with a side order of chaos.
Could his FedEx truck endeavor be the exception to the rule, or would it be going up in flames?
WhistlinDiesel has a knack for creative car projects
A lot of YouTubers spend their time modifying cars, but few of them do it with the flare that WhistlinDiesel does.
Lest we forget, this is the same guy who turned a Tesla Cybertruck into a fully remote-controlled vehicle over three days – before destroying it.
And then there was the time he installed 17 turbos into his Dodge truck.
More often that not, these misadventures end in flames.
How would things pan out with this FedEx with a jet engine?
Let’s keep the fire extinguisher on standby and take a closer look.
WhistlinDiesel wanted to do a jet engine swap on a FedEx truck
Detwiler and his team started off with a 2005 FedEx truck that the former owner swore ‘ran perfectly’.
It didn’t, as the multiple failed restarts demonstrated.
Deciding the original engine was a no-go, they decided they needed something to fill the ’empty void’.
That’s where the Viper 11 jet engine came into the picture.
“This is a 3,000 horsepower jet engine going into a truck with no brakes, no power steering. In regards to your safety question, no, it’s not safe, but where’s the fun in that?” Detwiler joked.
Just reading that sentence is enough to make you want to grip your seat in anticipation.
How did this FedEx truck fare when it came to deliveries?
Touted as the ‘first FedEx truck to offer same minute delivery in the country’, the first delivery lived up to the hype.
It was on the second delivery that things took a turn for the worse.
Without power assist, the steering proved to be a struggle, and a prop rabbit that’d been left in the cargo area was sucked into the engine intake at full throttle.
That’s a sentence you could only read in a WhistlinDiesel story, right?
Things only got more complicated as they arrived at the wrong address.
“I am not sure whose package this, but you can have it,” Detwiler sheepishly said, passing over a complimentary package.
While taking a break at a gas station, they realized that the starter had died again.
“There are some things on this earth that are not meant to be. I don’t think I’m meant to be a delivery driver,” Detwiler said.
“I have went through four different starters on this jet engine. Each of those starters is $250. So, you can do the math.
“I want to do cool stuff like this, but cool stuff doesn’t work out ever.”
At least nothing ended up exploding.
