IAT vs AAT on stock LS3 intake

[stigmundfreud]

finally got around to doing some logging, cant find richs thread about his AT vs IT but with stock setup my car is on average IAT reading at 12 to 15 deg C above AAT.

How accurate that is has to be checked but its scary to watch IAT rise quite rapidly when stationary even in this chilly weather.

There are some shitty intakes around.

to be fair the logging was done on only 3 shortish runs last night after the car had already been rather hot. Be interesting to see the averages on the way down this morning to see how it is from start to finish. IAT raises by almost a degree every few seconds at traffic lights though. How much is intake design and how much is the sensor location is to be seen
