Found a nice little surprise today flying the Ta152.

Cruised around for about 60 minutes with MW50 activated, throttling up and down from 90 to 110% during various engagements. On the home stretch I was coming down from 6k and my engine started to make grinding noises and pretty quickly sounded like I had severe engine damage. Naturally I was puzzled because I take really good care of my engine and I can't even remember the last time I fried one through misuse.

And then it dawned on me: The MW50 must have finally run dry and I fried my engine by not turning it off.

Seems like recently the MW50 actually has its maximum 30 minute reservoir taken into consideration. In nearly 5 years of flying I have never seen it run out once, but after all this time it looks like this small but important detail has been finally added to the game.

Imagine that

In German machines, there are very specific rules about using MW50 and other boost types regarding altitude. You engage the boost at the wrong altitude, and you'll destroy your engine.

I don't know the rules for the different aircraft, but I have often fried my 109's engine coz I engaged boost at like 1000m instead of at 4000m, or whatever it was supposed to be.

you can activate MW50 at any altitudes if you decrease your throttle below 70% and then increase it to 105%. Some guys sais that engine will fry if you put throttle to 110% but it have never happened to me.

but what does it matter, IF MW50 juice runs out???? nothing. It just quits producing more power cos there is no more juice, or does there happen something mechanical chances as well in the engine that makes MW50 work?? or is it just one valve more?

I understand that switchin MW50 or others boost ON can hurt engine if it produces so much more power, that it would " HIT the parts with parts" if switched on, while on full power without no wep, but when rising power slowly, it would not hurt plane, but. isnt this very same as an issue with every engine, not many engine can withstand FAST power increases, but decreases yea, same with many type of engines, if max powers are used intstant from idle.
