Message	diameter to get the correct pressure ratio for maximum thrust without the afterburner running. I dont have a variable nozzle for this engine and the video you see was the 2nd time I lit off the afterburner. I wasn't sure if the new design I used for the afterburner setup would work properly and I didn't want to hack up the nozzle until I checked that I would get a stable burn. I also am only delivering a small amount of fuel to the AB unit - what you saw there was the engine running at its maximum power output while keeping the turbine inlet temps at a maximum level of 1400F. Once I open up the nozzle, it will lower the turbine inlet temp and allow me to pour in a lot more fuel to the AB. I need to figure out some way of building a variable nozzle though - the afterburner will guzzle tons of fuel if that were all I could effectively run the engine with.
