Erhöhte Notleistung

[Leo Etgen]

Hi guys

I have been researching some into the specifications for the BMW 801 D-2 engine and the effects that erhöhte Notleistung had on the preformance of the Fw 190 A-8. Unfortunately there seem to be a number of conflicting figures given for the power output that this system had on the fighter. I have seen that the BMW 801 D-2 was rated at 1,700 PS for take-off and emergency and 1,500 PS for climb and combat. Are these figures correct? Regarding erhöhte Notleistung, I have seen that this boosted power output to 1,980 PS while other sources give a figure of 2,000 PS. Could some one please inform me which is the correct figure? Many thanks.

Horrido!

Edit: I have read new information by Crumpp from www.white1foundation.org in which it appears that the BMW 801 D-2 was improved in the summer of 1943 with a revised exhaust system and new fuel pump among other changes that increased output to 1,800 PS at take-off and emergency and 1,560 PS at climb and combat. This was the engine fitted to the Fw 190 A-8 and when erhöhte Notleistung was fitted it boosted output to 2,050 PS.
