Hi all. I continue to make good but slow progress on my EFI 8 stack system.

I am at the point of deciding where to locate the Air Intake Temperature (AIT) sensor, sometimes called the Air Charge Temperature (ACT) sensor .

Various assembly instructions/articles I have read on line show a rather crude method of installing the AIT sensor.

A hole is drilled in the intake velocity stack/trumpet and two threaded bungs are ground down to match the curve of the velocity stack (one bung inside and one bung outside). See pics attached.

The resultant assembly looks kind of crude to me and of course none of the "glamour" pics on any of the EFI 8 stack manufacturer wed sites show the detail installations, only lots of glitz.

Also, there are two versions of AIT sensors. One is a brass straight version which sticks out of the velocity stack quite a bit. And the second is a 90 deg angle black plastic version which is more compact and may not look as obtrusive. Both are GM spec sensors widely used in EFI systems. See pics attached.

I am thinking of locating the black plastic AIT sensor in the throttle body below the velocity stack flange where it may be less obtrusive/visable and will require a smaller hole (and a custom aluminum bracket to hold it in place).

So can any of you give me any tips or show me pics of your EFI 8 stack injection systems with close-ups of the AIT sensor installation.

Thanks for your help.

Cheers
Greg
