I didn't want to dig up an ancient thread, so I thought I'd get opinions separately. My IAT sensor is currently in the stock location in an aftermarket lid, near the neck. I also have a 100mm aluminum MAF housing using a LS3 card MAF, but the IAT connector is just zip-tied out of the way. I ordered one of the recommended separate thermistors which is faster reacting (if only I could find where I put it ) and also have an IAT extension harness.
I've read some various threads about the speed of the airflow being high enough between the filter and the combustion chamber that it wouldn't matter if I had the sensor near the hood latch, or near the windshield wipers. Others say to put it in the intake, but since I have an LS3 intake I no longer have the EGR opening of the original LS1 intake and I'm not going to butcher my intake.
What I want is to have the most accurate temperature reporting for the air mass entering the chamber while minimizing idle heat soak and false lean AFRs without changing PCMs. Has anyone tried using thermal insulation between the top of the radiator and the base of the air filter housing, or around the intake tract?
Recommendations?
