190 A's prior to that of the A8.
Having a hard time finding the video on internet so that everybody can get it, no ISBN on the box.
The video is called "Focke-Wulf FW190" and (seems to be) a part of the "Fighter aircraft of world war two" series. It's released by Eagle Rock entertainment, Pegasus.
A number you can search on is PEG 1228 (which is the number for the video).
This is a link to a company in GB that sells their videos
HERE I did a search on Google for "PEG 1228"and found that page, can't seem to find that particular video though on the site, you can probarly write them about it if you want the video, or ask me and I'll pick up another copy in the bookstore and send to you. Price around 10 dollars or so.
Anyway, although the narrator (as in all films) says some things wrong, it's the interviews with the pilots that makes it very interesting, they interview Günter Rall and Otto Stammberger amongst other, aswell as Douglas Barder (the story he tells is freaking fun btw

).
While they interview Otto Stammberger, he says that when the Spitfire Mk9 arived, it could do everything as good as the 190's they were flying at the time, and some things much better (climb and turn for instance). He then says, and I quote:
We had to quickly develop something better so we brought in a Water-Methanol injection system to cool the engine down and that was an improvement of 60, 70, 80 PS and once again we were faster then the spitfire.
Can we get better first hand information then this????
Also, what fuel do the 190's in AH use?
Edit: Might add that the Water-Methanol system was introduced quite soon after the arival of the Spit 9 thus being in opreational service on versions as early as the A5.
