Crimea map, wind/turbulence off, cockpit off, default load, 100% fuel, prop pitch 100, radiator closed, speeds given max/max continuous, all speeds rounded to nearest 5kph.

ALTS LA5 /LA5F\\ //LA5FN\ //LA7\\
0050 520 555/520 585/555 610/575
0500 530 565/530 595/565 620/585
1000 540 575/540 605/575 630/595
2000 555 585/555 620/590 645/610
4000 575 570/570 595/585 620/620
6000 610 615/615 635/635 685/685
8000 585 595/595 625/625 665/665

-LA5 is limited to 100%, no WEP so max and max continuous are the same.

-I think LA5F continuous should be identical to LA5, but they are a little different at/above 4000m, which doesn't seem quite right.

-The LA5FN/LA7 are kinda opposite the P39, in that rather than an airframe that wants to go fast with an engine that can't get it there, they have an engine that makes them faster than their airframe wants to go.

-The supercharger gets shifted at 4500m, so they are kinda lame at 4000m (and my online experience confirms this, LAs are dogs at 4000m, P39N-1 puts up a better fight at that particular altitude than an LA5FN does).

-WEP gives alot of power at 2000m, but by the time you get to 4000m it doesn't really do anything (which only adds to their woes as they go higher but before they can shift supercharger).

-There are two temperature guages, opening the cowl flaps affects one, but not the other, so you can't really cool the engine down except to throttle way back and wait a long time.

-Due to the constant speed prop you need to lower the "prop pitch" to get the RPMs down.

-LA5F is pretty competative with FW190A4 up through 2000m except it has lower continuous speed and trouble with cooling.

-LA5FN is comparable to FW190A5 until you get up around 4000m, LA7 is noticeably better than FW190A9, also until you get to 4000m.
