I have air intakes on top of the hatch. Quick sum, its about 50 sq cm.
i spoke with wren today, they said that as the EGT gets near 50C of the max EGT limit, it will back off the pump.
On the ground i can get near 750 as its accelerating.
They also suggested it was ok to raise the EGT to 850 from its current 800c max.
I think they also said i could back out the thermocouple slightly, as jason is suggesting.
Having read the boomerang thread, i wonder if its worth shifting my turbine back slightly, to reduce the chance of reingested hot air.
true a typical of 3mm is ok for the termocouple.
and yes i alsways had the exhaust outside the airframe
