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.
