In this video from the Expo Performance 24 in Quebec you will view a Mustang GT500 Super Snake literally tear a mobile Dyno to pieces. Apparently this car was previously tested at around 900 hp and was going to strut its stuff at this auto convention. Well the owner thought wrong, because the Super Snake proved to be way too strong for the mobile dyno he was trying to put numbers on.
The damage caused by the dyno coming apart seemed to be somewhat significant as far as body damage and suspension damage. The main thing is that the drive is ok and so are all of the bystanders.
