Ad.1
"Note how it says "Steig- und Kampfleistung"? That clearly shows that these tests were NOT performed at WEP which is referred to in German as "Start- und Notleistung"! So 650km/h at non-Wep can easily be 666km/h at WEP...
And there is a "Steig/Kampf" and "Start/Not" rating for both 1.3ata and 1.42ata meaning that "Start/Not" at 1.3ata does not relate to 1.42ata effectively. "
You know that until med 1943 Db605A was derated to 1.3 Ata - which mean "Steig- und Kampfleistung"
So 1.42 Ata ("Start- und Notleistung") was not allowed until mid 1943.
So real performance of G-2 in 1942 and Bf 109 G-6 early ( 1943) was 1.3 Ata only - as its is in trials which i present.
Ad.2
"Have a look at the G-6 table! It even says "Vmax Not am Boden" (=Vmax WEP at sealevel) = 570km/h. Thats even 40km/h higher than what I have modelled right now, be thankful for that Wink
Anyway I cant imagine that the G-6 actually reached that speed at sealevel with the ordinary DB605A when in 1944 a G-14 with 1800PS at takeoff was barely doing the same!
And then look at "Vmax Not V.H" (=Vmax WEP at full throttle height) = 650km/h. Thats what the 2 G-6s go up to now instead of the old, undermodelled 630 & 635km/h!"
You look more carefully for these charts.
570 km/h at sea level is for 109 G-6 with MW50 equipment. The same plane without enabled MW 50 reach only 495 km/h at sea level.
Also what is improtant Bf 109 with DB 605 and with MW 50 could only used climb and power setting ( in these case 495 km/h at sea level) or with Mw50 enabled ( emergency power) and reach 570 km/h. There werent middle postion in the throttle level.
Look the same charts. There is 109 G-5 with Db605A clered only for 1.3 Ata
These plane reach :
0 km - 495 km/h
6.5km - 625 km/h
So these is reall performance of these planes.
So G-5, G-6 with Db 605 A at 1.3 Ata - up to med 1943 shoud look like these:
0km - 495-500 km /h
6.5 km - 625-630 km/h
and with 1.42 ata from med 1943
0km ~ 520 km /h
6.5 km ~640 km/h
These we have in these RL German Charts
