Production figures?
Yes, that is included too.

Could you please exactly name these documents? Names, numbers, where to obtain?
I have several documents relating to the BMW 801F which do not contain statements regarding the production.
I have also several documents regarding the Fw 190 A-9 not referring to the engine as an F of some sort.
I have explicit statements from BMW and Fw that state the F will not enter serial production before May, 1945. A copy of such a statement can be found in Peter Rodeikes Fw 190 book on page 270. While it is just a secondary source quoting a primary one, it is easily available so anyone can look it up.
The report quoted in the Peter Rodeike book dates August 3rd 1944, so it's hardly and "end of all discussion"-document.
It also states the avaliability of an engine of similar power-output (BMW 801TS as opposed to the TH (= F engine)) as the actual F engine.

I also have several documents that refer to the BMW801TS engine as the "F series".
All of them are dated AFTER 01 January, 1944.
Originally Alkohol-Einspritzung was to be used on the BMW801H series and GM-1 on the BMW801TS series but that evolved as GM-1 was approved but not encouraged because of intake icing. Remember the BMW-801D series was never approved for operational use with Alkohol-Einspritzung.
Also the D-series production simply incorporated many of the design changes developed for the BMW801F and E series. The pistons, supercharger impeller design, fuel pump etc.. all became standard on the BMW801D2. These and improved C3 fuel allowed the manifold pressure increase to 1.58ata as a simple pressure increase without any additional anti-knock protection.
The S and H series have the same simple manifold pressure increase to 1.65ata in the first gear supercharger. The power output is the same with the only difference being the use of alkohol-wasser to raise the H series to 2400PS at 1.82ata.
In January of 1945 the S series motor was approved for alkohol-wasser at 1.82ata.
In January 1945, a simplified Alkohol-Einspritzung system was adopted and approved speeding up fielding as well as production.

Absolutely not intended as such, in fact, it is to open up the discussion with a source that's easily available to everyone. You are most welcome to post later (primary) documents that may support or contradict the statements.Originally posted by Bremspropeller:

That is a bit difficult to understand - it says the TS engine has the same power output as an TH (F) and will use the designation BMW 801S.It also states the avaliability of an engine of similar power-output (BMW 801TS as opposed to the TH (= F engine)) as the actual F engine.
I don't have any later documents that state otherwise.
However, I think digging further into that is moot anyway, as the TS engine has the same power-output as the TH (F) engine - which basicly answers the initial poster's question.
The only drawback of the TS which I could identify right-away would be the non-avaliability of Erhöhte Notleistung due to the weak (= not beefed-up) prop-gear.
The original poster was asking for the 2400 hp F model, the TS wasn't rated that high, as it was limited to about 2000 hp just like the 801D (but with higher full throttle altitudes). Only the erhöhte Notleistung of the F series would bring the engine in the vicinity of the 2400 hp mentioned. What might have been available for the TS would be the 1.82 ata with about 2250 hp max, but that would have been the end of the line. That necessitated MW50.
Beefing up the prop-gear doesn't look like an unsolvable problem to me - that's what the quoted report deems to be the limiting factor on the TS
Yes, and that's why the engine was supposed to be good for 2250hp.
Different question - have you ever seen a picture of a 190 A-9 (in service) with the MW50 logo?

Sure it was....
IIRC, in July of 1944 the new prop gear was available and in production. It was required for the F series motor.The only drawback of the TS which I could identify right-away would be the non-avaliability of Erhöhte Notleistung due to the weak (= not beefed-up) prop-gear.
