Questions regarding the FM of the Fw-190 A-8/9

[War_Emergency_Picnic]

In
the 4.11.1, I noticed some of the previous features on the Anton series
were taken away, especially the A-9.

1) the A-9 does no longer have the "ërhöhte Notleistung". I only have a
PDF from "classics hangar" which shows that it had been implemented to
the A-9, but even so, is this the case? The only explanation I can find
is that the auxiliary tank was used to add extra fuel. If given the
choice in-game between extra fuel or extra speed, I'd pick the latter
more frequently.

2) is the flight distance of the A-8 shown in the object viewer
representative to real-life and in-game? If so, isn't this pessimistic?
The only way, I think, to achieve such low numbers in the A-8 was that
it was running at maximum WEP power non-stop.

3) the radiators of the A-8/9 are no longer automatic. Is this the case
too? A video in YouTube showing an interview with Arthur Gartner hints
that it is automatic. He says that during dive-bombing, "it opens up".
This may indicate the radiator opening up to compensate for the
over-revving engine which auto-system was unable to compensate. Can
anyone confirm this?

4) a little bit off topic, I was testing out the Spitfire IXe 25 lbs the
other day at MTO on engine limits. It baffles be that the Spitfire,
although it overheats, never had its engine die. The only possible way
to kill it is if you "hang on your prop with 100% prop pitch" for ~5
minutes non-stop. Either the Spitfire is going super fast (which it
isn't) or the liquid-cooling system in it is very effective. Can someone
confirm this as it is IRL?
