(CHT) cylinder head Temp.., where does the sender mount? (on a 6) Options

[DougC]

I need to pick up a CHT gauge and sender and was wondering where the sender mounts on a 2.7L six?

...how different do you think the temp at the exhaust header point of connection to the heads would be off?

i did this on the last car i ran a CHT (a T-III). i wish now i'd compared the two locations but oh well...

the exhaust flange location is going to be affected by EGT - which often moves in the opposite direction of CHT in response to tuning changes.

aircraft use CHT and EGT gauges because they have operator-controlled mixture setting and radically different power regimes (roughly: takeoff, climb, cruise, descent). we (well - most of us...) don't have in-flight programmable mixture.

there's something to be said for monitoring oil temp for indication of overheating - and using the alternator light as a sensor for excessive CHT (when the belt breaks, the fan stops...)

i wonder if it's possible to get thermocouple rings for 12mm plugs?
