Hey what kind of header temps with a infra red gun are you guys seeing , engine warm @ idle , hottest point on header?
i would not think a gun could read a fully warmed engine exhaust.i just have an EGT that reads 1320+/- after a run aqt idle.i think a gun goes to 900F.

My gun reads to 999 , egt would be lots higher than infra red ,egt is in the path of the exhaust , infra red is outside jacket , egt is the way to go for real #s but for the rest of us infra red will have to do

EGT at idle versus header temps at idle below 1100 RPM will be a bunch lower than 1000 F, or they should be. Running the motor at or above 1200 RPM will make both temps go up
that must be my problem.i have high idle. emarine01are you thinking of wrapping the headers or thinking of other things?how about some pictures it is winter.
