I want to make one comment, when i mentioned that the compressor is at a stall point at the right of the map, thats not entirely true.. the Only STALL marking is the SURGE line, if the Compressore map continued to go to the right you would jsut get more contours of lowere efficiency.. I think you are reading The maps incorrectly Demon.
jsut my $.02 ... i might be wrong, but I dont think so...
