So are you saying that some Italian DB 601 powered aircraft were powered by former German engines and not Italian built ones? also on the service life note, how long were the service lives of Alfa Romeos as opposed to the Daimler benz engines?
It is very interesting info. I've read it copied for myself. Recently I thought why japans started production of DB-601A engine with t.o.power 1100-1200 h.p. in 1940 while germans already prodused DB-601E/F version with t.o.power 1350 h.p. Why japans did not begin directly from it?Only the Aa motor was cleared for export, including licensed production. It is a detuned version of the 601A-1, but you have to remember the context is throttle altitudes. It has a smaller blower casing to reduce the throttle height, thus detuning it for the export market. As it turns out that also means slightly more output at lower altitude, but high altitude performance suffers. At 5000 metres you might have 150hp less in an Aa motor versus an A-1 motor and that is what is meant by the Italian measurement. You comparatively measure at the same altitudes, the A-1 has better altitude performance.

Its interesting remarkManfred Weiss produced DB605 engines for Hungarian built Me-109Gs and Me-210Cs.
I guess that Hungarians either as Italian simply produced DB605 according to german documentation. But Japanese had to modify DB601A to get more power. For ex. they did not change dims. of cylinders. while in DB605 bore was increased.Did Hungarian built DB605 engines have technical problems similiar to Japanese and Italian built DB601 / DB605 engines?
Where does this statement come from? What is official source of it?None of these two engines were permitted for export or license production.
Kawasaski began manufacturing of licensed DB-601A engine so non of other engines could appear to be Ki-61 installed on either JuMo or Merlin or Allison alike.Why?
Alternately it could have been powered by the 1,340 hp Jumo 211F engine which was also in production during 1941. Both of these German V12s were reliable.
