I was wondering if anyone could tell me what differences they have seen in their EGTs relative to differences in ambient temperature. Are EGTs substantially lower when it is cold outside (say 40 degrees Fahrenheit) as opposed to hot (say 85-90+ degrees)?

Thanks for the replies guys. Ambient temperature does have an effect on air density and combustion so I thought maybe it would be more noticeable. Makes sense that post-combustion would be fairly uniform though now that I think about it. Colder/denser air going in would result in more fuel being metered by the injectors resulting in larger/hotter explosions which would offset the increased cooling efficency of the radiator -- until you idle down anyways. Probably still a small effect relative to 1000 degrees though.


ISurvivedNMU: I'm a ways south of you -- down near Lapeer.
