1.98ata testing

[Charles Bavarois]

Hello Kutscha,

in a Daimler-Benz document dated 10th Oct. 1944, filed after a meeting at the “Entwicklungskommission Flugzeuge und Flugmotoren” on 3rd and 4th of October they remarked:

“Es wird beschlossen, dass die Umstellung der zurzeit in Wunstorf befindlichen 70 Motoren DB 605 ASM durchgeführt wird, wobei der bei diesen Motoren mögliche maximale Ladedruck von ca. 1,9 eingestellt wird, der dann ca. 1900 PS Leistung ergibt“. Roughly translated like „We decide, that the changes (for higher boost) will be done with the 70 engines DB 605 ASM, currently at Wunstorf. The boost for this engines is to be set at around 1.9 ata maximum, which will make around 1.900 PS output.”

I think, this makes it quite clear, that the testing of higher boost on unit-level was with Bf 109 G-14 AS and not on K-4s. BTW: II./JG 11 got its K-4 only after 20th Dec. 1944, having mainly G-14 AS and 2 G-6 in early December.

Testing at the manufacturer continued of course: Daimler-Benz weekly report dated 28. Nov. 1944 lists a Bf 109 K-4 WNr. 330.103 with DB 605 D and a Bf 109 G-10, WNr. 490.128 with DB 605 D on
tests with MW 50 and 1.98 ata Aufladung.


Greeting
Carl
