Ford Mustang Tire Blow-Out During 150MPH Dyno Run !!

Strapping your car to a dyno is a great way to get a glimpse at how the car is operating and how much power the engine produces. Usually, the car is run up to top rpm in a single gear, and then let return to idle from redline, with the dynamometer calculating horsepower and torque put down to the wheels. While usually safe and low-risk, a new video highlights precisely what can go wrong on a dyno run.
A Ford Mustang GT was strapped to the dyno at a car show, running on what the video claimed was a 200 shot of nitrous. The dyno operator ran the car up through the top of fifth gear, where its wheels were turning at the equivalent of around 150 mph, something not usually done. The operator let off the throttle, and the resulting shock unsettled an already-stressed left-rear tire and caused a severe blow out on the dyno.
Due to the speed of the spinning wheel, the tire was forcibly ripped from the car and flung rearward. The flying rubber caught the inside of the wheel well and ripped off the entire rear bumper. A solid metal section of the wheel well was punctured and twisted beyond repair, along with the whole left rear bumper section. That’s not normally the result you expect from simply testing your musclecar’s performance, and it highlights the importance of paying attention to tire speed ratings.

Take a look at what can happen in a worst-case dyno scenario in the video below.
