Thanks for helping last time
You're welcome.
One thing to note - there is no such thing as 'military power' for piston engines that are not of American origin. Soviets, for example, used terms 'nominal power' (my understanding is that is a 30 minute limit) and 'forsazh' ('forced regime' - not all engines were equally capable to do it - equivalent of the 'war emergency power' in US parlance). The 'take off regime' was another setting and usually included both over-revving and over-boosting vs. nominal power setting.
Some Mikulin engines were using take-off revs and boost also for combat - basically, emergency power. That gave another 200-250 HP vs. nominal power at sea level; less above 1km altitude.
Note that US 'war emergency power' involved just over-boosting, not over-revving.
I'd point you at this thread: link. There are tables and graphs there, translated, and spread in several posts.
Please note that AM-38 was not allowed for emergency power, at least not by manufacturer. The AM-38F was, and AM-42 was.
