You need to compare power curves for both 601A and 601N etc. Also i dont know what engine is used for 109 C in game. Most 110 C used Db601 engine and some used 601N but what i remember there were jabo version with bomb racks which cut some speed expecially at low alts ( with densy air). 601N had more adventage at high alts over 601A then at lower alts.

Eheheh I'm an engineer by education I'm more complicate than you think

I refer to the C-7 variant, which should be entirely equipped with the 1200 hp DB601N, three/blade propeller, rising the payload from 500 kg to 1000 kg (two 500 kg bombs).

Given that the speed / drag relationship is quadratic, and the thrust / speed is *broadly speaking* cubic, I doubt that 9% more power gives only <1% more speed. But I can be wrong ...
