Intake Air Temp Sensor Relocation Kit Worth It?
I bought one from a local guy who never used his. I only paid $25.00, so I thought at least I wouldn't be losing much on it.
I'd be particularly like hearing from someone who has objective experience with it, or at least has a solid basis for their opinion.
Personally, I wouldn't think it would have much affect, but who knows.
Cheers!

No, I don't have objective experiance, but you should read Nathon's piece on "useless mods"

Somebody needs to tell nathan to quite reading so many books & do some real testing on the dyno , I've got most of these mods done to my vette I'm having it dynoed sat. before I put the exhaust on this will be the second time I know theses mods work.

One might question the report, but to go to the opposite end of the spectrum and off the deep end by flatly stating to stop reading books, is absurd.
My position is that if someone else has already done the testing and reported the results then why re-invent the wheel. Repeating tests done my reputable shops has little utility and a waste of time to my way of thinking.
Re-locating the sensor only serves to send the ECM cooler air temp data which will cause the ECM to command a slightly richer mixture. This may or may not be helpful depending on the PROM programming.
Like so many other "tricks-of-the-week", from the test results I've seen in the mags relocating the MAT sensor shows no virtually improvement in power.

Just about the same angle, right?

even if it makes the car run 2% better or give u 1 horsepower increase I would be happy, If you ever rode a horse one horse is very strong

I will put it this way...
Gordon Killebrew was asked this question at a gathering last year. His answer: "It won't make any difference. The IAT is already mounted in plastic, and moving it forward isn't going to cool it down enough to make a difference. Now, if you have a ZR1, where the sensor is mounted in metal, that might make a difference."

The only reason I can see for using one is to be able to use the less expensive 91 duct from the throttle body to the air cleaner housing. Here's mine...

2% of a 400 HP engine is 8 HP! Now that's a TON for a simple mod.
Take for example a full, high performance exhaust system; headers to tail pipe, including FlowMasters (which everybody seems to LOVE, beats me why tho). Dyno results show in the range of 13 HP improvement.
One mag article build-up involved such a performance exhaust modification with the cost well over one thousand dollars. They got low teens improvement. HorsePower TV regularly does similar mods and the results are the pretty much the same.
So using those examples, you're saying that moving the MAT sensor is worth more than half of what a full, expensive, yet still streetable, performance exhaust up-grade gives. So what I mean?
Now, the other number: 1 horsepower; you'd never be able to verify that on the dyno because of the repeatability factors involved and the dyno's margin for error.
I won't even get into riding a horse but that analogy doesn't work either. LOL
Might as well come to grips with it; they're just a waste of time and money. Of course, you can always do what you want, it's just that some things work, but that ain't one of 'em.

The ratio of your hypothetical HP gain from IAT relocation vs the HP gain from the exhaust upgrade you are referring to has zero relevance to whether the IAT relocation works.

Actually the only reason people see and Increase is the tune on there cars was not correct in the first place. Fact
Next you will be tring a tornado! Let me save you on that one...10 HP lose on a 420RWHP 396 LT4 car!
Almost all the things like this you see are just cheap ways to lie to the computer so it will run leaner. Kind of like porting the MAF.
Go to far and you have a broken parts

Remember it wasn't "MY" hypothetical HP gain, it was his. I used his 2% and 1 HP figures to put things in context. Sorry you're not able to understand the basic reasoning.

If you run a MAF system the IAT sensor is justthere for EGR operation. If you run a MAP system, relocating it will skew the fueling tables, which will require some .bin mods and burn to straighten them out...putting you right back where you were before relocating the sensor.
