Nice car! Turned into a wing when it hit a bump:
And, like our guy here, he miraculously survived the inadvertent flight.
See: Fred Marriott (wikipedia)
That happened last year.
I have watched a few car building shows. They are frequently doing things, usually via bolt ons, to make these vehicles perform in a manner they were never designed to perform.
Most of the guys do the entire powerline front to back, so they do not blow thinks apart but the overall frame and body designs remain unaltered. When you put some ridiculously powered engine in a vehicle that was never meant to go faster than 70mph and sometimes less, you get all kinds of interesting failures. This is just one of them.
Ruined a classic car even before crashing it….
Early Corvettes were prone to this. Pete Brock mentioned this to his bosses at GM when he worked there, and they ignored his concerns. He went on to design the Daytona Coupe, which is much better aerodynamically.

The C2 corvette was a lesson in downforce and what happens without it. The first C2 road racers found out pretty quick that anything over 110 mph they could turn the wheel and the car would still go straight. Not so much as not enough downforce as it was the design of the body actually generated lift.
In the fall of ‘72 I borrowed a housemate’s Karman Ghia to go out to SeaTac airport to pick up another housemate who was singing for change out there and needed to get there fast so I got up some speed. At just under 70 I felt the car rise on its shocks and thought uh oh, this thing is going to fly and put the brakes on thereafter keeping it to 60.
What my 1967 437 fastback felt like it was going to do as I approached 135mph. When the nose rises enough to start blocking your view, time to back off.
