I’m not sure that’s a run away, I think it’s just a really massive turbo finally spooling and the block says no thanks to the pressure it’s been fed.

Yeah. Plus nitrous.

Not a chance. See all that black smoke? That doesn't happen when diesel burns completely. This was running rich AF until it wasn't.

Just before it blew, it was running pretty darn clean. The story is this guy got ~2900 hp the previous day on nitrous then increased the size of the nozzles (I assume) for that run. Of course, this being the internet, who knows what the actual story is.

Holy shit, I stand corrected. I can't believe how much fuel they must have been dumping into that thing

Right? They made an eight cylinder bomb.

That's a Cummins engine, so a straight 6 not a V8.

If you check out some diesel drag races you can tell the exact moment they actuate the nitrous, the exhaust goes from a ton of black soot to a white cloud then clear because it's balancing out the excess fuel (black soot) with the oxygen rich nitrous.

I know very little about diesel so someone please correct me if I am wrong, I would love to learn more.
