    Looks similar to the numbers in IL-2 Compare for 4.07. I did look at that and realized that yes the FW190D-9 on boost is a wee bit faster till about 7000m or so. Acceleration has always been high for the D-9 series...not sure if it was accurate or not. Similar things can be said about the dive...both Mustang and Dora are relatively low drag with high power...no idea on the numbers but we're talking about somewhat similar aircraft.

    One thing to note is that the Mustang at 100% power is quite a bit faster than the D-9 at 100% power. Its only the boost that gives the D-9 advantage. Moreso the 1944 version than the 1945 version. This could be a completely accurate (technically) representation of both aircraft but the reality being that the boost was less used on the D-9 than on the Mustang. I don't know...I know that the high boost puts allot of strain on any engine and that it was somewhat more rare to use in WWII than we do.

    yes in game we all use boost as much as the motor will allow for im sure. IRL thay had to worry about not only the mission thay were on now but the many missions in that same plane thay were yet to have. just like in your personal car. only a fool would run it WOT "wide open throtle" all the time.

    Forgive me, but what does
    "80% power to cruise"
    mean?

    On the face of it, the blower operation and full throttle heights don't appear to be badly represented, so it's probably best to use them - i.e. in this case set cruise rpm and maintain the appropriate MP using whatever throttle is required, as determined by your altitude.

    Yes, high speed once achieved can be maintained at lower 'settings'. In some types, the difference between settings appears extreme.
    As an example, the P51 climbs quite happily at 2700 rpm 46" MP, as per the book. Nowhere near 100%, 100%.

    Though it doesn't need saying, I'll say it anyway - If you're in a position where you're being overhauled by a competently driven FW (or anything come to that), then you've lost already.

    There is more to all of this than meets the eye...

    80% throttle. when im cruiseing. when i get to my disierd Alt and get some speed i reduce throttle to 80%. and prop to 90% so the motor stays nice and cool while still haveing good speed.

    High RPMs is where you get the extra heat. If you want to make better highspeed runs then
    get close without loading up heat in your cooling system.

    I've found that keeping the throttle at 100%, rad auto, and engine rpm around 2700 keeps the engine very cool.

    I've also found that in a flat dive (1 to 2 barwidths low on the artificial horizon) I get to 400-450mph very very quickly.

    Consequently, I'm able to engage my online opponents almost at will (given the alt must of the online lufties fly at); and, if I don't do something stupid am able to extend at will.

    It's the 'not do something stupid' and the 'I can't seem to hit the ground if I fell down part' that I have trouble with.......

    I find this testing interesting. I rarely fly the pony, but there are only rare occassions, I find, where anyone really has a chance to get to their desired altitude, get all trimmed out, gain airspeed and start looking. This single factor seems to have more bearing than true performance figures.

    Simply being at altitude doesn't give the P-47, for instance, an advantage over any other adversary. You have to be at altitude and have gained some airspeed. If I've just climbed up to 6k and leveled off maintaining only about ~300kph then even a poor high-altitude performer like a 109-G6 (late) can outperform me if he was already there cruising with a cool engine and running ~450kph or so level.

    I know this sounds obvious, but so often people will base their performance claims on random situations online with many intangibles and no controls. I was in a K4 the other day and had just got to altitude (5k+) yet hadn't had a chance to level out and gain any airspeed. I merged with a couple reds who were already established at alt and they drove me away. The very next sortie, I gained 6k and was cruising at almost 500kph when I merged with 2 more reds (a pony and a jug) co-alt. A few cannon strikes on one and 2 extended bursts of mg on the other and they were diving away licking their wounds. I didn't bounce them and didn't have more than 100-200m advantage.

    I realize this isn't the gist of this thread, but only say this to make a point about relative circumstances affecting people's opinions about performance.

    It still needs repeating, though. 95% of the "Why is my plane porked" threads stem from not taking this into account.

    agreed 100%. my tactic kinda drives my online friends crazy as i gain alt over base BEFORE heading out. less chance of getting jumped and if you do you may get warrning from base flak as well as beck up. in servers like the big_top i out run LA-7s ect in my tempist all day because i got so alt and maintained a high rate of speed and cool moter. in war clouds i use the same tactic as much as i can.
