Which is, according to the link you provided, 1,23 ata @ 2300 rpm. Not quite the 1,3 ata Kurfürst was talking about.

Everyone has there knickers in a knot about max speed but what speeds are obtained at lower the ata. Hense what I posted.

If the 1.23 ata speeds can't be met, then there is something definitely wrong with the FM.

The problem is the Il-2/COD engine seem to just state the max. power, and max. speed at max power. The engine calculates the rest. And then engine power calculations are again relate only to max power, and a generic formula takes care of the rest for lower powers.

I guess , so you probably won't get exact speed results for lower RPM/MAP combinations, for example you probably won't get the exact cruise speed at ~1 ata cruise settings as in real life.
