Well for a given speed and altitude, and plane configuration (throttle,
fuel, ordnance) there is a certain number of g's you can pull in a turn
that will not cause your energy to decrease. This is called Sustained G's.
Above this you will bleed E either by slowing or descending, below it you
will gain E by either acclerating or climbing.
As an E-fighter, you only want to exceed sustained g's when it allows
you to get a decisive advantage (i.e. nice guns pass) on the bandit.
Unfortunately we don't have the plot in our hand showing what this g-level
is! Unless you want to do a LOT of test flying, you have to learn to estimate
it by trial and error. But if you are pulling more than 3-g's it is safe
to say you are blowing E!
One time you can exceed sustained g's is at the top of a zoom. First
of all, you've already stored a bunch of energy by zooming, so you've got
some to burn. Second, when you make a downward turn (e.g. you are inverted
and pull back on the stick), gravity will add an extra g to your turning
ability! So the plane can be losing energy at the rate of a 3-g level turn,
but because of gravity assist you are actually making a 4-g arc.
Finally, BUY SHAW'S BOOK! Fighter Combat: Tactics and Maneuvering. He's
got a whole lot of material on this style of fighting, as well as very simple
and clear info on the physics involved. His explanations are much more thorough
and well-written than my own.

There were some E-M charts for a few Warbirds a/c posted in CombatSim
a while back. Have you guys seen this?

It seems that the energy preserving turns are usually in the range of
2-3 Gs only.

A simple rule of thumb is the "90-degree rule." Never turn
with your opponent for more than 90-degrees of turn. Figure out how long
it takes to turn 90 degrees in your favorite plane at attack speed (300-400
mph, depending on the plane). Then count to yourself that many seconds.
Be disciplined and come off your target rather than continue the turn. Of
course, if you get a shot somewhere in there, take it :-)
90 degrees is just a starting point. In the Corsair, unless I'm engaging
a Mustang or FW, I won't track a target for more than about 45 degrees of
turn unless we have a big numbers advantage.
Also, remember that going to 0 G with max power will rapidly rebuild
your energy reserve. You can use this in sustained climbs (briefly) or in
dives to gain back the E that you lose while manuevering.
