The winner of that event was none other than Aaron (Rudy) Rudolph and his nitrous-fed 6.4L Power Stroke. After making 1,041 hp and 1,829 lb-ft he tried for a bigger, better number. Triggering the nitrous with only 10 to 15 psi of boost created a blown head gasket and a massive nitrous backfire. This photo is the result of the carnage that occurred on the gasket. Although a piston could’ve been burnt up during the endeavor, this was the extent of the carnage done to the engine that day.
The head gasket now hangs as a trophy in Rudy’s shop, along with a bent intake valve and broken rocker arm, which he broke at subsequent dates :)
