Folks,

I'm running a Kraftwerks Rotrex kit with the supplied intercooler. GM IAT sensor mounted an inch or so below the 90 degree hose going into the throttle body. The air filter is sealed from the engine compartment by a Racing Beat fiberglass shroud. Air is pulled from under the driver's side headlight. I usually see IATs 12-15 degrees above ambient around town and on the highway, and 15-20 degrees above ambient on the track. Two different sensors gave similar readings.

Is that normal?

Thanks,

 

Yep, good even.

 

My engine bay is stock other than removing the AFM and replacing it with a pipe with the IAT sensor in it. I see 15-20+ above ambient all the time. Idling at a light I usually see 130-140F.

 

8-10 over during cruise on my setup, GM sensor right by throttle body as well.

 

Thanks much.
