I guess I'm surprised that the outlet side of the IC is consistently hotter than the inlet side (except at high speeds)... even with no flow the IC must be radiating some heat? Why at time "0" is the post IC temp ~55C and the pre IC temp ~30C?

car had cooled down from previous idle, for about 2 hours. Time zero occured after cool down and about a minute during which the car was pulled out of the driveway and I could hit the log record button. Prior to engine start, the temps post IC was mid 30's. Which wouldn't be too suprising.

Was the IC already heat soaked?

partially warmed up at time zero.

It doesn't make sense that the charge is hotter after the IC than before... what's heating it up again? The engine compartment is not 55C, is it?
|
I have measured the TMAp postion with an infrared temp gun after driving previous to tonight and it is at mid 50Cs. May be cos the TMAF IAT is much farther away with rubber airbox outlet/TB between it and the SC as opposed to the post IC temp probe location.

I'm wondering if the probes are measuring the temperature of the metal surfaces, and not the temperature of the charged air?
|
I made sure the probe on the post IC side wasn't touching anything (bars/fins in core) and positioned somwhere in the center before the outlet coupling on IC.
Fixture is brass or copper I think and came as a kit with the probe. The pre IC side probe is exactly the same.

OK, too many questions... I've got to take a little time to digest your data... it's certainly not what I expected to see!

yes please do. I have got to go to bed, hope to read on further analysis over breakfast
