"the Aces High model universally limits WEP usage via engine temperature" AH wikii thingy..............
I tested the Ki 84. It does cool down twice as quick with the engine off. This backs up what i stated.......Never said anything about throttle down.
I do see ,to some degree, your point about time.
ON the Ki 84.For every second u let the engine cool u get two seconds of wep. IF you turn it off it does it quicker by double....I'm sure that could be expressed in degrees as well for every x degrees engine cools down you get x degrees till wep shuts off..
I did not test TOTAL wep time for the Ki 84. I have know idea what that is.... From the looks of your test it is cyclical till you run out of fuel.
Maybe Hitech will reply and clarify seems like the P51 should have a total which is less than your test. bug maybe?
