It would "seem" than plugging the hot nozzles would be "ok" as long as you don't set the mixer to hot (which then also plugs the cold ones). My understanding is perhaps overly simplified (and/or potentially wrong/confused). Would love to be set straight if so. I can not comment relative to engineering design, but the Super Legacy does not use cabin pressurization, therefore all sonic ports are plugged. Compressor stall is not a problem there. I assume the non-pressurized IV is the same. Craig Berland
