That`s nice and all, Crumpp, but little more than wishful thinking, for I have just checked and the number of A-9s (inc. various Rustzustand variants) were less than a hundred in December 1944.
Sure Kurfurst. Only one factory, Focke Wulf, was producing FW-190A9's from September 1944 until December 1944. In December three more companies began rolling the type off the productions lines GFW, NDW, and Arado.
NDW being the most difficult to track down. Their production was a closely guarded state secret. It actually caused a bit of political spat between Norway and Sweden when the Foundation discovered some of NDW production documents in an Eastern European Archive. Planes were being manufactured in Sweden!
Knegel no A series 190 used 'MW-50' as standard with the exception of a few odd ball A-4s for vengeance jabo raids against England. The A-9 like the the A-8 utilized C-3 injection.
No it did not. The BMW801TS1 was specifically forbidden to use any boost system at all. Once more, none was under development for it. From the BMW801S installation and operation manual:
The BMW801TS2 could use MW50 and was tested in Jan'44. That same month a directive come down to begin installing an emergency Alkohol-Einspritzung on the FW-190.
C3-Einspritzung was used on ground attack variants starting with the FW-190A5. It gave excellent performance but could only be used below 1 KM in altitude. It also was a different system from the "Erhöhte Notleistung" used in 1944 by the fighters.
That system is here:
Alkohol-Einspritzung was tested by simply did not perform as well and added the additional weight of antiknock agent tank.
I believe the emergency MW system ordered into use in Jan 45 had more to do with fuel shortages than perofrmance increases. While "Anlage für Erhöhte Notleistung" used a different injection rate from C3-Einspritzung, it was still a fuel thirsty system.
All the best,
Crumpp
