To return to the original post, later in the war many Mosquitoes were fitted with paddle-bladed propellors, resulting in a significant increase in the RoC (a la the P47). If (as Jabberwocky suggests) the aircraft in question had the more powerful engines, plus the paddle-blades it would almost certainly have been able to outclimb an Fw190, which was not outstanding in this regard compared to the Spitfire or Bf109.
Additionally, Coastal Command Strike Wings often used their Mosquito VI's as fighter escorts when Spitfires or Mustangs were not available, and they appear to have more-or-less held their own against German fighters, achieving a roughly 1:1 exchange rate judging by post-war analysis.
