The grill and headlight fly off the front end like it was shot from a cannon.
Here were are at a Dyno event somewhere in Truckadilly, Montana and these guys decided to put up their LB7 Duramax to see what kind of power readings they can get. This beast is nitrous powered too, so they aren't going for a fuel only reading. So the truck is running as a typical coal rolling beast should be, emitting plumes of guilt into the air when the nitrous backfires and the front end explodes. The front grill and headlight is ejected into the area where the crowd was standing. Luckily nobody got hurt.
