Max EGT on 20v BT

Hey guys,
Does anyone know what temp should EGT be at in a 20v? I've got timing advanced and wideband is indicating a great mixture but the temp seems to be a bit high.

EGTs are a hard one to place exact numbers on since it depends on a lot of variables and especially how far your pyrometer is from your head.
900 C is often used as a good rule of thumb.
On my turbo BT my pyrometer is about 16" away from the head and I get pretty close to there regularly while boosting in closed loop. Haven't had any issues yet.

My layout is about the same, but I am running NA and hitting between 780 and 900.... Thanks yoshimitsuspeed

What is your ignition timing? Advance should reduce EGTs.

I've got it advanced at 20. I have never been past the 900 but it was a concern that it operated that high.

20 deg BTDC?
Is that with the diagnostic connector jumped?
