If Germans pilot had the ability to choose I'm not sure they would hve taken the pain to carry heavy water tanks up to 5/6K to boost their eng.
The C3 optimized eng was a real relief on that point.
Regarding the quality of the materials used in german engines, I would only point out the respective wet weight of Allison, DB605 and Jumo engines. Pls remind that late vers of all those 3 had nearly the same output power.
It remind me the engine mount designed for the Allison powered D9 flying today (warbird). The goal of the engineer was to add weight to get back the right balance (usually you work with a contrary objective).

Note : sry to dig out tht one. :-p
