[VIDEO] A Dyno Assistant’s Arm Gets “Run Over” by a 2019 Corvette ZR1


[VIDEO] A Dyno Assistant's Arm Gets

Weapon X Motorsports held an open dyno day in Cincinnati on May 5th and one of the attendees brought a Sebring Orange 2019 Corvette ZR1 to the event.

Those sticky Michelin Pilot Sport Cup 2 tires on the ZR1 tend to pick up rocks and other debris and then launches them when running on the dyno. So a “dyno assistant” uses a broom and with the wheels turning at very low rpms, he brushes the debris away.

Unfortunately for this dyno assistant, as he was cleaning off the driver’s side rear tires, he got a bit careless and the brush was caught between the dyno roller and the wheel, pulling it and his arm under the large rear tire.

Here is an account from an attendee at the show who uploaded the video to YouTube:

“I attended dyno day at Weapon X and they were dyno-ing a new 2019 ZR1 Corvette. Basically, because of the street tires someone had to brush all the rocks off the tread so they didn’t fly out. The guy who was doing it got a little careless and got the broom bristles stuck while the wheels were rolling and got dragged under the tire,”

Luckily, we see the guy get up immediately and talk with someone in the car. It appears the only injury was his pride as we are sure this video will be around for a while.
