Hello again
Finnish AF flew performance test on Messerschmitt Bf 109G-2 a/c code MT-215 on 5 Apr, 1943. The result was max speed 636km/h (TAS) at 6700m and c. 520km/h (TAS) at sea level. Climbtime to 7000m was 6'20" and to 5000m a little bit over 4min. I figured out the climb times from not a perfect graph, so some caution here. MT-215 was carrying full ammo and had 400l petrol at start.Tests were flown in "Steig und Kampfleistung". Radiator flap position had very big influence on speed and also on climb. Up to 50km/h at sea level. So at a warm day the figures were clearly worse.
I have for a long time suspected that the 386 or 387mph max speed was flown by a Bf 109G-6 night fighter with 20mm gun gondolas under wings, which had landed in error to Manston in May? 1944 (was that the plane that became TP814, a Bf 109G-6/U2 with 20mm gun gondolas under wings?). But I have no proof on that.
