In a thread about WEP, HiTech himself stated that WEP in game was based on a timer. For example, the P-38 has 5 minutes of WEP. I can run WEP until the needle is just below the red zone (for this example, lets say it took 4 minutes with WEP on to reach) and then turn it off and let it cool down until the needle is back in the green. I turn WEP back on and it will cut out before the engine temps hit the yellow zone because I only had 1 minute of WEP remaining.
ack-ack
But the temp gauge only exists to measure WEP availability. So I'm betting that P-38 gauge is faulty.
And overheating too; nevermind
