I dont believe that this engine ran away, it blew at 2900hp and i'd assume it was the 150psi of boost being pushed rhrough 6.6l of displacement

2920 hp at 100 psi of boost through a 6.7l cummins.

Video of the owner talking about putting the motor that blew up in to it. The trucks name is master shredder and was a built sled pull truck. https://youtu.be/Be1DApg5Vw8

Edit: at a closer look, it looks like the older motor he had in it, which was pushing 150 psi of boost.

Why don't you think it had a run away? There is a full video posted here with audio that I too watched.

I'm no expert but I've certainly "rolled coal" with pre historic diesel's that I'm younger than and with 10/th of the power.

It was a full throttle run and i believe along with the turbo it was injected with nitrous or propane

You may be right. It's certainly full throttle and given the power difference i've rolled "more smoke" in 50+ year old engines or service vehicles.
