Ya wanna give my list of questions a shot? Thats kinda vauge to answer with your own corrected quote.
For every american, german, russian, spanish and south american ww2 forum I've been to the answers vary and are even argued by common members of several of those forums across forums. Many of them appere to own original documents, libraries of books and some work for restoration companies. For every expert it is only thier answer and everyone else is wrong. There apperes to be about as many personal modern truths about FW190's and BMW 801's as were rolled off the assembly lines in ww2.
The 2700rpm 1.56/1.65 looks like it would be for a petrol injection to air intake. But which supercharger gearing to achive 1800hp+-? Or are we using late war MW50 at 2000hp with the S gearing? Then would come into play which version of the "Power Egg" for these production aircraft? But then, Starting from July 1944 all Fw 190 A-8 aircraft will be equipped with "increased emergency". By overridding the supercharger boost regulator, boost pressures are increased at take-off and emergency power in low supercharger setting from 1,42 ata to 1,58 ata and at the high supercharger setting from 1,42 to 1,65 ata.
Reads like petral injection to the air intake.
D2 - 5.31:1 to 8.31:1
S - 6:1 to 8.3:1
But, you also read some places MW50 very late was allowed for the A8 boosting to 2000hp or so.
TS and TH did not stand for turbocharger but instead the Triebswerksanlage version of the Kraftei or "power egg". MG was the "power egg" designation for the A8.
I have been confused at times over engine designations as so many trying to speak about the FW's.
Engines were typically delivered from BMW complete in their cowling, ready to be bolted to the front of the aircraft, since 1942 as Motoranlage (M) and 1944/1945 as Triebwerksanlage (T). The Motoranlage was the interchangeable Kraftei, or "power-egg", unitized powerplant installation format used in many German wartime aircraft, most often the twin and multi-engined designs, with some need for external add-ons, and the Triebwerksanlage was the Motoranlage plus some external mountings, such as exhaust pipes, as a completely interchangeable unit, as the Kraftei concept itself was.
The M and T versions confuse the naming considerably, as they referred to these complete kits and their "bare" engine counterparts almost interchangeably. The A, B and L models were known (logically) as the MA, MB and ML in this form, but the common D-2 was instead known as the MG. The E model was delivered as the TG or TH, seemingly suggesting a relation to the G and H engines, but in fact those were delivered as the TL and TP. It is rather common to see the turbocharged versions referred to only with the T, notably the (most notoriously of all) TJ, and the TQ models, further confusing the issue.
It's not too hard to figure the A5 2700rpm/2400rpm 1.42/1.32. So I think it's in Janes from 45-46 a BMW power curve graph showing about 1800hp on petrol intake boost and 2000hp+ on MW50 for the 801D. But then the 801S is rated 2000hp emergency and take off. Is the MW50 boost version what Babs is talking about?
