Same settings as the FW190A-8 test posted earlier.
(Altitude)(Time-)(Ft/min)
(05,500ft)(0'55")(3,600)
(10,500ft)(2'20")(3,500)
(15,500ft)(3'50")(3,400)
(20,500ft)(5'20")(3,250)
(25,500ft)(7'05")(2,375)
I find the time to ~20,000ft historically very accurate. Official data say about 5'50" for a DB605DC powered 109G-10, but probably with a lot more fuel.
