Test Pilot Wrote:Bf 109 F-4 with Db601E, take of weight 2890kg, performance with 1.42 Ata
0km - 537 km/h
6.2km - 670 km/h
initial climb rate ~ 21 m/s
turn time ~ 20 sec
As far as I know the 670km/h topspeed given for the 1.42 ata DB601E is without compressibility correction. Actual topspeed is more in the range of 650km/h!

Notice how topspeed for the G-2 is given at 7km but for the G-6 at 6.6km? Actual topspeeds for the two G-6s at 7km is 640 and 650km/h respectively when extrapolating to the higher altitude!
22secs for turntime is also rather high. The Soviets have tested a G-4 to turn between 20.5 - 21.0 secs which is just 0.5sec higher than what they got for the G-2 (20.0 - 20.5).
Keeping in mind that the G-6 is just something like 30kg heavier than the G-4 I cant imagine it turning worse by as much as a whole second!
