Some follow-up questions... Who set up your engine? Lancair? Did you (they) get any "official" input from TCM? Is there anything different in the waste gate (slope) controller or turbos? Do you have any special power reduction procedures? (i.e. reducing MP slowly to let Upper Deck Pressure bleed off) Do you have much experience with it up high (i.e. 25,000 ft)? Perhaps the banter regarding compressor stalls with the sonic nozzles plugged is OWT (Old Wise Tale). However, know of several straight IV's (non-P) that still have sonic nozzles because they were told they needed them??? Rick -----Original Message----- From: Lancair Mailing List [mailto:lml@lancaironline.net] On Behalf Of Craig Berland I can not comment relative to engineering design, but the Super Legacy does not use cabin pressurization, therefore all sonic ports are plugged.
