    So i found this awhile ago


    As you can see this is data for flight speed of a FW 190 A9 with a late war BMW 801 TS making roughly 2250hp at 1.82 ATA. What i am wondering if anybody has any other data about this specific plane with this specific high power output engine setup, i am looking for something like climb charts, weight,configuration etc.

    So far this is the only historical reference for this plane in regards to flight data i have found, i would really love to know more about it.

    Thanks!

    more direct link to data if link doesn't work http://www.wwiiaircraftperformance.org/fw190/fw190-a8-3jan45.jpg

    I'm afraid I can't answer your question, though I want to know the same. What I find interesting is harsh collapse in speed of the BMW801A9 between about 1000m and 3000 in comparison to the Fw 190D9 (B4+MW50 at 2.0 ata). Both aircraft have single stage two speed superchargers. The in line Jumo 213 has a reputation for relatively good jet thrust, that may be part of it. This is due to it being philosophically like an allied engine: low compression ratio higher boost. I'm guessing that the BMW 801 stage 1 supercharger ratios were optimised for low altitude more so than the Jumo 213. The intercooled BMW801R was to receive 4 speeds (abandoned due to bomb damage). The follow on to the BMW 801TS (which was the BMW 801E optimised for fighter with provision for MW50 etc) was the BMW801F which I've heard it claimed was to have a 3 or 4 stage supercharger derived from the BMW 801R. The 801 might have benefitted from more stages.

    As the 1.8 ATA Jumo 213 was producing 2100hp the 2.0 ATA version must have been producing around 2340
