Greetings everyone. The datasheet found on kurfurst.org: Kurfürst - DB 601, 603, 605 datasheets - DB 601 Aa claims that on Dauerleistung power setting, DB 601Aa has an output of 950PS at 0m and 880 PS at 4500m. However, the way that the turbocharger on all DB 601 series engines works, their output at rated altitude is always slightly greater than the power they yield at sea level at the same RPM. Therefore, its is very unlikely that DB 601Aa should have whole 80 hp less at 4500m than it does at SL, especially considering that the former value is cited for a setting of some 100 RPM less than the latter. My guess is that one of these values is simply a typing error. The big question is, which one's right - 850 and 880 PS, or 950 and 980 PS, correspondingly? This far, I've been unable to obtain the power curves for 601Aa, which would've solved the dilemma once and for all. Does anyone have any documents on DB 601Aa not derived from this datasheet (values from NII VVS report certainly are), or any other info to provide insight on the matter?
