no bug High altitude power drop w/water injection

[Ketchup]

I’ve noticed some strange behavior with the P-47 water injection above ~32k feet. When throttle and boost are full forward, engaging water injection results in a significant drop in power. When the boost lever is then brought back 1 inch, power returns. You can then advance the boost lever almost full forward without seeing the drop off again (although this can lead to overspeeding the turbo).

I think it is turbine surge or compressor stall.

So this means that when you are at an altitude where power starts to decrease and you have no means of maintaining it, sometimes called Full Throttle Altitude. In this case the turbo will limit itself due to coming away from maximum efficiency.

@NineLine Thanks for the reply! That makes sense, appreciate the info!
