Runaway Engine

saw this twice on lobsterboats. one was a 6-71 Detroit and the other was 3406 cat. went off like a rocket. shut off fuel at filter use
fire exting in intake. shut down in about 8 seconds which was like an hour. if happened to me on the road I would try to sever fuel line
anywhere and use exting in intake and clean up fuel later

 

by simply cutting one of the connecting hoses from the air to air and pulling it away, would had cut the fuel (hot motor oil from the turbo) into the motor and it would stop by it self if the ignition was off.

 

Who says you can't learn anything off the internet? An issue i've thought of, but never experienced. I'd have never thought of simply cutting the air to air hoses.

 

Cutting the rubber boots won't kill it, still need to choke it out with a piece of flat board or mud flap. Turbo inlet.

 

i would have just stalled it out by putting it in top gear breaks and dump the clutch.

 

Thats a hard one to determine what is best to do. If the motor and turbo are under warranty let it go up in smoke. Putting the transmission in a high gear and dumping the clutch is insanity, that clutch could come thru the floor and take your feet off, there is a reason race cars have scatter shields or blankets around the bell housing. With the amount of shock load you could also bend the crankshaft, and spinning at those RPM's something will more than likely break and come thru the block. I would never try to open the hood and cut the intake hose, if something let go inside and came thru the block it could kill you, not woth the risk. If it happened going down the road then I would try to use the brakes to stall it out, if all else fails push the clutch in and let it eat its pigs.
