Shelby GT500 explodes dyno

This is every tuner's nightmare. You take your steroidal drop-top to the dyno so everyone can see how big your horsepower is, then just as you're reaching peak power the rolling road explodes.

Which is precisely what happened to this poor bloke. There he was, quietly enjoying an afternoon of bangin' choonz and decorative hats at the Expo Performance 24 in Sherbrooke, Quebec, when he decides he should probably find out how much power his Shelby GT500's making. Off to the dyno man, open throttle, create toe-curling amounts of energy in small area, EXPLODE EVERYTHING.

Now watch. Then tell us your tuner horror stories...
