Measuring heatsoak vs actual AIT?
I was at the track on the weekend doing some datalogging and saw some AIT's of 180odd fahrenheit. I really wonder if this is accurate.
On the dyno I dont see these numbers so I want to know how to accurately test AIT and eliminate heatsoak. The sensors are in stainless or alloy tubes right before the throttle. Regular GM sensors.
Can I dangle a sensor in the pipe or something to eliminate any chance of heatsoak? Run a hose over the pipe?
Pls help me get accurate AIT data.
Thanks,
Dann

180°F. Your IC is broken.
I'm going to say this for the 10,000th time: STOP PUTTING AIT SENSORS RIGHT BEFORE THE TB SO YOUR HOT *** RADIATOR *RADIATES* +200°F OF FURY ALL OVER THEM.
seriously, if I could enforce it, I'd make it illegal and fine/jail all offenders on this site.
move your AIT bung to your IC endtank.
But, with that being said, if this is while driving, I'd trust the readings. So long as you have airflow over the sensor element, it's going to report back fairly actual temps. Sounds like your IC is severely undersized/poorly designed for your application.

Just test and see if heat soak changes the readings.

With the SC, if I let it heatsoak at idle, the AITs dropped if stomped it and went into boost, as there was a rush of cool air from the intercooler that cooled everything down. AIT sensor would show this, and infared temp gun/hand test confirmed it too.
