This is a good old fashioned dyno disaster. According to the poster of the video, the cause of the failure was a wrist pin that left it’s duty post at the worst time possible, during peak RPM on the dyno. The engine blows up big time and barfs large pieces of the block out, which then allows hot oil, and perhaps some fuel fly, igniting in a scary fireball inside the dyno cell.
Dig the fact that the zombie motor seems to continue running until the dyno operator is screamed at to, “Shut it off!”
There are some swear words uttered at the end of this video, so it may not be work safe!!!!!!
