Home Depot'd my CAI and dropped my IAT 20 degrees!

So i installed this $60 Ebay no name intake a few months ago. CAI And i always wanted to seal it off from the engine bay, just never got around to it. Well my buddy was tuning it and told me if i got my IAT's down he could add a little more timing (idling for 20 minutes or so in the Texas heat with the A/C on full blast my IAT's were at 135*). So he suggested i seal off the air box. I did one better and made a crappy little scoop that gets fresh air from under the front bumper. Well i tried the idle for 20 min with A/C blasting test (outside temp was about the same) and my IAT's came down to about 115*. Even better is once i start moving they drop down to outside temp in a few seconds. Before at a stop light they would climb from 90* to about 117* then very slowly drop back down when i started moving. Now they climb from 90* to about 95* and drop back down to 90* in about 4 seconds after i start moving. I know it looks goofy but i don't care, it works.
All i used was some waxed cardboard i had laying around, flashing tape (you use this stuff to seal around doors and windows in your house) and some thermal barrier stuff. Spent like $20 total.

Oh i also repositioned the neck on my water pump because the radiator hose was on the bottom of my intake tube, which would heat it up. Also went ahead and took out my thermostat today and it's running quite a bit cooler, so my IAT's might have come down even more.

Your PCM looks at engine temp, it might screw things up.

I have that same ebay intake and I think it is well worth the 60 bucks

i run no stat and have no issues with that what so ever. Now in winter it can be an issue if you live in a cold state

My truck is tuned. I'm not trying to run the truck at 140* or anything. Just wanna keep it around 180*. If it gets colder than that i'll put in a modded thermostat. So far with no thermostat the coldest it gets after getting up to temp is about 190*.

the gauge doesnt show actual temp. my gauge reads about 170 and i cruise around 150

your gauge might show 195-200 and actual temp will be 215

There is a reason 99% of cars come with 195* t-stat

1. Engine needs to warm up to run properly.

2. Computer never comes out of "cold start warm up" mode.

Never run lower than a 180* t-stat.

i call BS on that since closed loop starts at 92 or 94* on these motors. if the motor is tuned properly for it, its not going ot hurt it. the reason they put 195 in for proper burning of fuel for everyday vehicles and emissions

You might have an issue as mine has a 160 in it and barely cracks 175 if ever. Then again, no tstat can make one run hotter because the coolant doesn't stay in the radiator long enough.

Closed loop starts at 153 degrees. Put too low a tstat in and you'll get P0128. With add on OEM efans and a 160 mine will set this code in the winter when the auto AC turns on the compressor and therefore the fans and the coolant never get warms enough for closed loop hence the P0128.

I would not say never go below 180 'cause a 160 does have a proper application but my 160 needs to be a 180 and I WOULD NEVER RECOMMEND NO TSTAT TO ANYONE for a driver, only a track only, TRACK ONLY vehicle.

i just looked up a stock tune file for a 02 4.8 silverado and closed loop is 131*

There is also a reason all cars come with catalytic converts too.
Like i said right now my truck is running at about 190*. Which is just about where i want it 180-190.

DTC sets on ANYTHING '96 and newer if ECT doesn't get to 153 in a certain time so we're arguing two different issues. But then again, 13X is too cool for optimum performance especially with heat shedding aluminum heads.

No offense man but that means you need a 180 tstat as described.

looks nice,
would a plastic intake stay cooler than a aluminum intake?

I have a PT3200 stall in a truck about 770 lbs heavier than yours. Almost all stop and go driving with the A/C on max at all times. So it gets pretty hot.
I know all about the codes these cars throw and monitor it plenty.

OK then. I doubt you're 770 pounds heavier but that's neither here nor there.

Oops looked at the wrong page.This website says it's 833 lbs. Almost 2 extra feet of SUV is pretty heavy.

5036 pounds LOL. I wish.

BTW, it's more like 14" not two feet :spit:

You're a lot faster than me with the high stall and cam swap and the headers and the exhaust mods none of which I have but don't make it something it's not :LOL:

Have a good time and be proud of the good numbers. Just because I don't like the idea of leaving the tstat out is no cause for alarm bro.

I don't know how accurate the weight is. i have yet to actually get mine on a scale.
But rulers don't lie.
My truck is
Length, Overall w/rear bumper (in) 221.4
Yours
Length, Overall w/rear bumper (in) 198.9
221.4-198.9=22.5
Just a little FYI, wheelbase does not = total length. :spit::LOL::slice::hshake:

+/- one or so inch using a tape on the garage floor I get 198" :wave:
