egt's after a pass

what kind of EGT is normal under WOT?

Be specific as to where you are reading. (e.g.-in the collector or at the port exit.) If you speaking of your specific application from what I vaguely know of it I'd guess (<)1450*F at the port. Ideally, you could balance port-to-port EGT's with jetting or intake manifold manipultaion. I'd taylor your AF first and whatever your EGT is...it is If you know what I'm saying. Because spk adv. has a large effect.

Exactly.
EGT's are good for cylinder to cylinder variations,not for dialing in A/F or spark advance. There are a lot of variables affecting the numbers.

a friend just dropped a valve in his boat. he has a egt on the number 1 cylinder right by the exhaust port which is the exhaust valve that broke.

i'm thinking his egt's were in the 1300 range

1300 is about normal BUT it make a difference whether
the reading is 1" off the edge of the flange or 2"
and so on.... at work(when I was) I tried to get a standard
of 1" so we could ALL talk the same numbers.... now
days I use the EGT just for balancing the intake
runners and I put the end of the probe right in the
center of the port dead nuts on 1"... I use a set
of calipers to set it
