IF you are using an infrared exhaust temp gun to check the headers;
Do you check it right after you make a run?
What RPM do you check them at?
What header temp would be ideal for the perfectly jetted carb?
I am assuming there is a percentage you want each header tube to read in relation to the other header tubes?
How do you use yours?
thanks

You cant get a good reading with a temp gun.. as
soon as you let off the pedal its cooling.. on the
race car I run 8 egts with a data logger... if you
can log the data you would like in the 1350- 1450
range at full power.. this can change some... I take
ALL my reading exactly 1" from the head surface.. have
been reading at that point even when I was working in
the exhaust lab so all of us would get the same data..
I finally got that as a standard point at work.. took
a while to finally get everyone to agree to a set point..
when I say 1" I measure that with a caliper so each is
right on the money(on the inside of the tube to the tip
of the probe.. thats where the reading is taken)
