nope, never heard of that. what exactly does that mean? what was lemega's turbo rated for though? the one on the bike was rated for 240krpm.
As you probably know, a mechanically injected diesel will run on just about anything that burns, this includes used motor oil, natural gas, kerosene, vegetable oil, etc.
The only way to stop most diesel engines is to cut the fuel supply, as they have no ignition system or air flow restriction setup. So when a diesel blows a turbo seal, the engine has an uncontrollable supply of delicious oil, causing it to rev as high as it can until.
A. It explodes
B. It runs out of oil
C. The driver freaks out and crashes hard enough to inflict heavy damage to the engine
D. Air supply is cut by the use of Halon or CO2, or an emergency shutdown safety valve on the intake manifold
I have also read of this happening in oil fields where clouds of natural gas can roam, engines used in these conditions must have an emergency shutdown valve.
