RE: Building my own intake, maybe.
I say you have too much time on your hands for all this thought. Really....Buy a K&N 63 series and run some hosing to behind the grille and attach the other end to the bottom of the airbox--where it gets the air from the fender liner....Some air ram like, and bim bam, you're done. No thermal resistance testing, no nada.

RE: Building my own intake, maybe.
I have a lot of time on my hands because I am currently on leave. This would almost be like an intercooler. I talked to a friend of mine who is a mechanic, and he said that would probably work pretty good. Like I said, it would probably bring in an extra 5hp... probably. Can't go by theory, so I'll have to go by testing and cold hard facts.

RE: Building my own intake, maybe.
Has anyone ever checked the difference in temp. drops from outside air and when right before it goes into the throttle body???
That would save ALL of your time right there.
Lets say it's 60 degrees out and the air going into the TB is only 65 (probably not the case though)....then a cold air intake won't do (too) much...u know??? Or even the cooling system that DakotaStone was thinking about.
I'd just check the incoming air temps. on a stock intake system first and then proceed from there

RE: Building my own intake, maybe.
well, I know this much. the engine bay gets hot. very hot. I am not 100% sure of stones idea, but I know this much. our stock intake tube is very restrictive. the idea behind a true cold air intake is to be as smooth as possible, and pull colder air. now the air you pull is going to warm up on its way to the T.B. but since it isnt taking as long to get there, and isnt warmer when its pulled, it is logical that it is cooler when it arrives. the colder is not always the better. too cold causes detonation. (it takes a very cold charge though.) I am sure our alaskin friend could tell us about his truck missing in the extreme cold.
now, the reason I am doing as much testing as I am is this... I want a nice system. I want to do it myself, but I dont want a half "A"ed system. I plan on making it with the intent of being a professional system. I will eventually get to the actual fabrication, but I dont want to waste time on materials that are infurior. ABS plastic is not the best... but injection molding allows many to be made for cheap. thats why K&N and AEM use those. I want something that I know will work. not just the theory, but the actual end product.
I am not trying to sound like an ***, I just read alot of DIY hater threads and dont like the way that those people look at "us" Not all DIY-ers are trying to just make a half-"A"ed project. I am taking this serious and want to get an actual gain. I know the big companies have a research team to do what I am doing, and I know they have dyno runs to prove the gains... I will have those as well (dyno runs). just not going to market it to the masses. If it works, I would love to make them for my friends. I do not intend on selling these, but I still want to have a quality product on my truck.
enough of this rant, I will sum it up as this: I want a nice intake system. I want it to be a true cold air system that looks like it belongs in an engine bay... and I want to make it

You are starting off on the wrong foot thinking that way.
Something is 'restrictive' if it has a pressure drop in the air from its inlet to its outlet.
If you think you can just look at something
(and your name is not Paul McCready or Burt Rutan)
and tell whether something is
'Aerodynamic'
or not
you are making a 'Newby' mistake.
The flow of air and water is full of constant surprises.
Sharkskin roughness, bubblebee flight, vortex generators on the front of whale fins, dimples on golf *****, Kamback automobile shapes....the list surprises goes on and on
That 'restrictive' air inlet tube with the accordian pleats
may flow air better than a similar length smooth pipe.
Measure!

RE: Building my own intake, maybe.
ok, let me get this correct... millions of people buy K&N and AEM with smooth intake tubes. they are all wrong. Unfortunatly I am no newb... I do research. even if you did know what my plan was, you totally mis-read the quote. by your logic, smooth is bad, but smooth flow is good. so read the quote again. "as smooth as possible." am I regarding the tube, or the air flow. you dont know, because you didnt ask....
so you find that one little thing in all of those posts, and you decided it was totally wrong. I guess you better write to K&N. that is a huge selling point for them.

RE: Building my own intake, maybe.
From what I've read, seen and heard, smooth is much better and our stock tubes suck. The restriction is from all of the "anti-noise" crap they put into the stock. When I bought my CAI and got rid of the stock crap, the noise level went up, and so did the response... More noise than response...
I know this hardly qualifies me as a "pro" in upgrading vehicles, but I watch Trucks! and Horsepower. Both of them say the samething about the stock box and intake. I talked to a speed shop when I first bought the truck and they said that the stock crap keeps the noise level down and restricts the airflow. The last place I talked to last month said that aluminum is better than plastic because of the heat displacement.
Seems to me that there are a lot of different theories and opinions. I guess it's just best that I stick to what I know and have learned.
BTW, I love the noise coming from the engine compartment, to include the sucking sound when it idles.
