adding IAT sensor to my 8746 with EBL/Prominator. 8746 platform for chev uses 89-92 F-B cars. i assume same part # for all?

using a 7.4 L TBI with standard round AC(2.0 in. x 14 in.). so thinking a IAT is a good idea considering i am sucking warm air. the stock crossfire hood on an 1984 vette does provide a cold air passage to feed prior CF air cleaner so i am getting some fresh air directly to each side of standard AC. but that is minimal. yup i know i need cold air ducting. that is coming another day once i locate a bonnet or fab one..

should i place the IAT within the AC or attach it to bottom of AC unit? or alternative location in engine compartment?

 

I have an open element that sits in my 4 inch cowl hood. So I put my IAT right on the airfilter, so it sees the air coming in whene I am driving. The temp of the air still rises at idle and slow speeds, but when I am going faster it draws air from the scoop, and over the IAT. I feel it is a more accurate representation on the air temp the engine is seeing. But, if you have a flat hood, then I would just put it in the air cleaner. GM actually has one that goes into the aircleaner via a d hole similar to the pcv breather hole, and is held in with a clip.

 

thanks. i found a post regarding that in EBL. but the auto parts counter guy will ask year make model as always and then he gets confused when i try to explain. do you recall what application is the clip in variety? that would be easiest for me to work with.

 

Just go to Autozone and have them dig out the GP Sorneson catalog. It will have pictures of all the IAT sensors that came on GM models and their respective part numbers.
