I have an IAT assemble (minus wiring, gromet, etc) from a friend's 99 truck. I am going speed density on the truck and need to relocate the IAT to a point after the meth injector anyway.

BigTex pointed to the unused EGR space in the intake manifold as a good spot for plumbing in the new IAT sensor and I'm trying to work out how to mount it there and keep it there under boost.

I've thought about glueing it in, but then if the IAT fails for some reason, I'm screwed. Any ideas?

 

Silicone it! You should be able to break the seal on silicone if you have to, but it will hold until then.

I'll think on it some more and see if I cna come up with something even better.

 

On mine I just drilled a hole in the EGR blockoff plate then put the grommet in from the back side and glued it all in place. Has been in there over a year with no problems.

 

How are you going to tune in speed density with boost??? You will max out the MAP sensor with very little boost. Are you going to use an after market standalone management pcm?

 

I've already done the SD tune. It's much easier to tune SD on a GM than MAF... The MAP limit is there with or without the MAF (in terms of VE and spark anyway).

 

if you do decide to use silicone, make sure you use an O2 friendly kind.
