Bye.Ivo

That's correct. If there is not an extra system (like water injection or mw50, which is stuff that's found on late-war aircraft), pressing the WEP key will just advance the throttle to 110%.

This is how it is in reality too, we just got confused and learned it the wrong way from all these years flying IL2 and now we have trouble understanding the difference

In most aircraft war emergency power just means going full throttle and nothing more. The extra systems that inject additional stuff into the engine usually are not there to produce more power, but to enable the engine to run at full throttle for a longer time without damage by preventing the detonation effect.
