Hi guys.
As we're in the middle of summer here in Aus and with local temps regularly in the vacinity of high 30's and low 40's, I thought Id pay someattention to the IAT temps.
Ive notice the biggest issue i seem to get is terrible heat soak if the car is left to sit idling for extended periods such as going thru town with the lights etc.
I have an OTRCAI but even with that it can take some time for the iat tems to settle down. Im also curious as to how much heat soak there is in the actual sensor itself.
On a logged run recently (high 30 degree day) I saw iat temps in excess of 50 degrees whilst stationary. Once on the move again it took another 10mins before the iat temps cam back below 40 and even then they didnt drop much further.
What Im curious to know is what is the ideal position to have the iat sensor??
Placing it directly in the air intakes path without anything around it to cause heatsoak would surely be the best scenario wouldnt it?
Having it mounted in the plastic corner of an OTRCAI cant be ideal as the plastic retains alot of heat even with some airflow thru it, and the air flowing thru wouldnt be increasing in temp that much. Ie the air being ingested wouldnt equal that of the sensor reading.
Would it be wise to mount the IAT sensor in the direct path of the airlfow into the intake but away from anything that could cause heatsoak into it??
