Hypothetical speed question, ;)
So we all know 94mph is the wall but if there were no limiting factors and took the truck up there what would the top end speed be if you just planted the skinny pedal on a stock truck with 4.10 and 18" tires (edit rims, 275/70s)?
I don't intend on finding out myself.

Slight imbalances adding up to catastrophe?
Are you saying its it’s like a tire having a max speed rating?
And your video posted above- why is that car capable of going 120mph if the manufacturer is aware of the driveshaft failing at that speed? I thought everything was supposed to be overengineered and detuned.

Yes, it's similar to a tire having a max speed rating. If you exceed the critical speed of a driveshaft it comes apart as shown in the Mustang video above.
I once exceeded the critical speed with a prototype driveshaft in an F-250. The rear end came off the ground as it pole vaulted the rear driveshaft on the freeway. That was exciting. When I hit the critical speed the truck started to vibrate heavily. I immediately knew what it was and hit the brakes as hard as I could. I wasn't fast enough. The shaft flew apart. This was at about 60 MPH. This truck had a modified driveshaft with a torque meter installed. I had forgotten that the max speed on this truck (because of the prototype driveshaft) was 55 MPH.
The car is NOT capable of exceeding the driveshaft's critical speed. Obviously someone added an aftermarket tuner to remove the governor.

So you're saying a true driveshaft can run at any speed?
