May I suggest you re-read the initial post Chadzat. In the circumstance described the aircraft never gets anywhere near a
'screaming 2850'. Power application
stops when the oil pressure gauge reaches the red-line, not the tacho. You are correct however in noting that the 520 does indeed have a time limit on max power, which a wise pilot respects.
UBE: precisely the point.

Whoops, sorry I didn't note to which post you were commenting.
I don't think CC is advocating leaving the 520 turning at 2850 (the 550 however
will happily turn @ 2700 all day) -as he states, in a normally aspirated engine, your power setting (MP) effectively starts reducing as soon as your wheels leave the ground. Winding the prop back to say 2700 for the climb has many advantages in performance, and is a 'good neighbourly' practice also. Those blade-tips going trans-sonic is bloody hard to listen to.
