I keep finding that the Fw-190A-9 had BMW-801 TS capable of 2000PS and yet im not sure if 1.65 ata is 2000PS for the engine in the sources that state that it has 568km/h at SL and 665km/h at 6300m.
I personally think its not 2000PS since from that power i would expect it to have 588km/h at Sea Level
