109 e4 performance

[Robo.]

Thanks for the reply Crumpp - as you see I am not in any kind of disagreement. The calculations are not really for me, rather for the sim. I find it interesting and if the 1c guys happen to read this or if it gets reported, we might as well end up having Emils closer to the real thing FM-wise. I know I am naive

5-10 km/h - i got your point point, but it is really about these small details and I pointed out that the 2 flights compared (rads open / closed) at 5000m were at different MFP and the difference was perhaps smaller than 50km/h.

Also agreed on the climb performance -most difficult to measure as enviroment is a massive factor. Funny thing is they got the top speed right and climb so much off when the a/c was the same. I also believe it might be fuel / coolant / oil / instruments. I also believed that particular 109 has been slightly damaged before - hence the 'components' thought, not just fluids. No further info on that provided...

As for the actual figures and calculations for top speed at sea level:

DB 601 A-1 / 9-9518A

1.40 ata 2400RPM 1100HP (1 minute)
1.30 ata 2400RPM 990HP (5 minutes) radiator 1/4 open 467km/h
1.?? ata 2200RPM 810HP (30 minutes)

DB 601 Aa / 9-9518E

1.45 ata 2500RPM 1175HP (1 minute)
1.35 ata 2400RPM 1045HP (5 minutes)
1.15 ata 2300RPM 950HP (30 minutes)

Anyone cares to fill in the blanks, ideally rad fully open / rad fully closed + E-3 E-4 aerodynamics + /B aerodynamics?
