The first dyno test for a freshly built performance engine can be stressful for the owner and/or builder – after all, it’s probably the first time that they will truly push the motor to its absolute limit.
YouTube channel 1320 Video recently filmed a Chevrolet Silverado Duramax blowing up spectacularly on the dyno, giving us a very good idea of why the initial dyno run can be a such a trying time for owners or engine builders.

In the video, which is embedded above, the turbo on the diesel Silverado’s 2,000+ horsepower motor grenades itself, engulfing the entire front end of the vehicle in smoke. The engine then begins to run away on its own oil, forcing the mechanic in the driver’s seat to try and hop on the brakes to slow the whole train down. As the brakes begin to glow red hot and smoke fills the cabin, the mechanic is forced to abort the mission and jump out of the window.
The dyno operators are eventually able to extinguish the flames, although it does take a minute due to their household-size fire extinguishers.

The diesel Silverado in question was perhaps doomed from the beginning. The team behind this truck, Dirty Hooker Diesel, finished building it just a week prior to the drag, dyno and trailer pull event that it was filmed at, so it seems to have been put together somewhat hastily. We hear the team got back to work and rebuilt the truck to run the trailer pull event the next day, though, so they definitely deserve some kudos for pressing on and not giving up.
Check out the video embedded above.

The motor didn’t “grenade itself”, the turbo blew up.
So where are all the EV naysayers who are always quick to point out the dangers of battery fires? This was mighty dramatic!
While I agree this was a dramatic failure, the concerns about EV battery fires I think are related to how hard they can be to extinguish and their alleged penchant to flare back up.
Ronjo Do you even know what the test on this vehicle is for ? The Truck is for competition , In sled pulling ! This is not your normal operating trucks !
Here I am! How about the fact that EV’s when a battery is damaged blow up when parked in your garage right by all your life’s memories and possessions, or in downtown traffic engaging others. At least gas engines never blow up unexpectedly and only on a Dyno where you understand the risk. Further chemical fires are very hard to put out.
Take a screwdriver, puncture a lithium ion battery and get back to me. Kids that’s sarcasm, it’s extremely dangerous, it’s a chemical burn
Ronjo, That is a %100 custom built, 2000+ horsepower race truck. Comparing this in ANY way to the potential fire dangers of a STOCK EV car is ridiculous. If stock trucks were at risk of this kind of failure, they would never be sold in North America.
LUKE SPOKE THE TRUTH.
Yea GM,Chevrolet.GM stands for GARBAGE MOTORS.
I wouldn’t go as far to say the engine was hastily built. The amount of time, effort and money teams put into building a truck for UCC is unbelievable. Even fielding a truck at this event can’t be done “hastily”.
The worst in the car industry ,see my page in Twitter @ccaplanis
GM will soon follow Ford and RAM in using CGI for the Duramax engine blocks
