I agree 100%... One "mechanic" was even pumping his fist in the air like he was in Jersey Shore at a night club.

Cut off the supply of oxygen is the best way to stop it from running away. A phone book as mentioned earlier against the turbo intake, or a towel stuffed in the intake tube. There is an element of danger and personal injury, but I have NEVER been a bystander and don't plan on changing any time soon.

I had a 10 yrd mixer do this (main engine kickback into reverse rotation) while backing a steep incline to a foundation. Spooky to say the least, but shut her down by clutch quick!
Kinda miss that old Bull Dog on the hood, and even the 5x4 twins on the floor!

On a trip back from the islands we had a Detroit run away while under way, it was a heck of a ride; we could've water skied behind that 80' boat. As we were pretty close to our destination and the engine wasn't over revving, I kept the oil topped off until we were in the ship channel and then fed it a couple of pillows, the emergency stops didn't shut it down. When the air was cut off the engine died and we were able to continue to the customs dock with the other engine. After viewing the videos of the truck I don't think you would have time to open the hood, pull the air cleaner off, and stuff the intake with a shirt or something before a rod came through the block (metal flying everywhere). Unlike the boat there was no load on the engine to keep the rpms down.

Stories like this make me want to plumb one of these directly into the intake.

Or a guillotine on the intake like the tractor pullers use.

Had a runaway once on a 7.8l Ford diesel. The fuel injection rack got jammed forward and it ran away on diesel instead of oil. Crazy ****.
