MAT Relocation????

I was looking into this. Wouldnt it make sense to have it where it it on the intake to get a more accurate temp reading closer to the point where it is actually burning? Getting a cooler reading from the airfilter box or accordian doesnt make sense to me unless you are trying to trick the engine into doing something. I really dont know that much, and most of what I learned about these things is from here with you guys! Help me out, shed some light.

If the move is worth it, what if any gains has anyone gotten? Seems like one of those....pass on mods to me. Correct me if I am wrong.

The TB bypass made sense so I hopped on it, the frisbee blew my mind why it was even on there, gone! The Airfoil is in, doing what.....I dont know!

If you have the airfoil you might as well do the MAT relocation. The airfoil does nothing. The MAT relocation helps with the fuel mixture a little bit. You can do it for free if you have some wire and a soldering iron.

Just ask yourself a question? If it isn't important why do new cars have their MAT located away from the engine.

I saw a new high performance vehicle where the MAT is located in the front grill and we know that GM wouldn't do this unless there is a reason.

I think that it helps. The plenum gets pretty hot and will transfer heat to the MAT, fooling it. I wish that someone would make an L98 intake manifold out of thermoplastic. I probably couldn't afford it, but then that is what dreams are made of.

Re: MAT Relocation???? (GusBustamanteJr)

I posted a tread called "MAT to hot" last week, I continued to get an error code 23 (MAT sensor out of range) anytime the car was at an idle. I relocated the MAT sensor to the air box and my error code went away! :yesnod: what it did for me was smothed out the idle, a smoother accleration. I didn't need to buy the kit from ZIP products. I ran the wiring myself total cost was 22 bucks including wire, shrink tubeing, wire loom and a new MAT sensor (that Came with a new weather pack connector) and aout 1/2 hour of my time. Just to make it look pretty. :cool:

I agree on the accuracy of air temp.

Think about how fast the outside air moves through the intake even at idle. I doubt that the air temp drops 5deg from my cold air intake scoop to the valve. Compare that to how hot the IAT gets screwed into the bottom of the plenum.

In the air filter lid is a great location for an accurate intake air temp reading.

Re: MAT Relocation???? (Rynda)

A company in Cali used to make composite plenums for TPI cars. A guy on Thirdgen.org bought one from E-Bay last year. I had the manufaturer's name cast into it but I can't remember THAT name. I remember the auction pretty well.
