Hmm, weren't Hoof's data based on WEP performance ?
Anyway, as far as I know, our G-10 uses standard D 605D engine.
From Warplanes of the Third Reich:
“…The standard DB 605D engine, using 87 octane B4 fuel and methanol-water (MW 50) injection, provided 1850 h.p. for take-off and 1600 h.p. at 19 685 ft…”
The 109K-4 used DB 605ASCM or DB 605DCM engines.
“…Daimler-Benz DB 605ASCM 12-cylinder liquid-cooled inverted-vee rated at 2000 h.p. for take-off, 2030 h.p. at 1640 ft, and 1800 h.p. at 16 400 ft…”
Same book gives 452 mph top speed of the K-4.
I agree it feels like WB K-4. The torque is more pronounced, however, but so it seems on most other 109s.
