AIT sensor install question?
#42
Thread from the dead....question about IAT location S/C
Hey sorry to bring back an old thread but I'm trying to figure out where to put my IAT sensor when I install my new MS. There's a comment here about 'assuming your not supercharged'. Can anyone explain this?
I have a 95 and am currently running an Eaton M45 S/C. The car came this way and it's my intent to install / learn / tune the MS this year and then go turbo with (probably) a BEGI setup next year.
So with a S/C where's the best place for the IAT without tapping the intake mani? BTW - I have the plastic crossover tube.

It needs to measure actual air temp as it enters the intake. So after the SC and if you were to have an IC then after the IC. Since you don't.... it needs to be after the SC so it's reading the temp of the SC heated air as it enters the engine and can account for that properly. If it's a plastic tube... um... JB weld a bung to it maybe? A metal tube you can weld a bung to. But that's where it needs to be or you'll have issues.

Thanks! As I thought. So I can just do as richard_ha did in the photo above but just before (or in) the dummy TB.
I plan to try out water injection too. I assume this won't be an issue for the IAT sensor in any way as long as the water is atomized in the crossover tube before it hits the sensor?
My pre-built MS is on the way! What exactly do I need to order from DIY for MAF deletion? It's not coming with the IAT sensor, is that all I need? Which one, the one with the pigtail I assume?

I doubt there would be enough issues to matter. If the sensor can measure the temp of the air coming into the intake then it should be fine. Air escaping out the BOV shouldn't make that big a difference. Maybe if it leaked at idle and caused a 10* change for some reason you could have issues. Not like you couldn't tune for that though.

The BOV across from the IAT/MAT should be fine, it's venting air out and not in as long as it's functioning properly, and when the BOV is open you're not under load, again assuming it's functioning properly.
On plastic pipe... um... either epoxy a bung to it, or I've actually heard of people drilling a hole, and putting the bung INSIDE and threading the sensor through the hole into the bung holding it in place. But that's usually the ghetto o2 sensor mount and I don't think I'd do it on an IAT as it would be really ghetto and dangerous if it came loose. Not to mention hard to seal up under boost.
Really the best answer may be incorporating some aluminum pipe...
