Anything that conducts heat located in a 150 degree envirornment is going to get hot.
That's like saying the upper intake manifold on my Mustang isn't going to get hot on a 90 degree day. It gets too hot to touch quickly and it flows air.
Why ice down an upper at the track after only 1/4 mile? It's hot.
They may have done some extensive intake temp testing in the shootout as I remember them remarking that there was a big temp difference on the WMS system without the shield in place. This is only about a 10" long system. I can see if I can obtain any data on this.
But we're really getting sidetracked with the original thread, partly my fault, as I was trying to show that there is differences in different plastics' insulative properties.
You have to let potential customers know the differences in construction otherwise most people would simply consider that there is no difference with plastics. Another example of this would be the different shielding materials on the market: ABS & PCV, as all plastics, have a temperature ceiling before distorting and warping. I'm not at the shop where my plastics manuals are so I might be a little off with these quotes but it's around 140 degrees before ABS & PVC start to warp. It's 240 degrees before polycarbonate will warp.
With an emphasis in the shootout writeup denoting 'how the system will hold up in the long run' it's significant to know the temp limitations of different plastics. Plus, cosmetically the polycarbonates look AWESOME, a very high gloss black, and very stiff for squaring off the airfilter location corner.

The intake temp was measured close to the filter, this was done to see what diff a shield does. It was measured with a regular termometer, not very sientific but I think with the data recieved quite conclusive!
I'm getting the Tun Ind system and not until now I realized we were talking about 'warping' issues...
I have been talking about coolest possible intake air, in the largest possible amount (tube interior diameter + filter size, open ended), through the smoothest possible tubing with the smoothest possible bends...!!

Nobody could have said it better than you JP you said "potential customers"
In other words you have a biased opinion which I believe shouldn't be in a forum such as this one.
I have been biting my tongue for over a week now but this is getting ridiculous as to how much emphasis you guys are putting on the metal versus plastic debate.
A 4.6L engine at 80% volumetric efficiency will flow 388 CFM or 11,000 Liters per Minute@6000rpm!!!
The air is flowing through the intake at speeds of around 6000ft/min
NOW DO YOU SEE HOW STUPID THIS WHOLE HEAT GAIN DEBATE SEEMS

Thump! I had been wondering where you went... Glad you're back!
I do agree that JP/John is quite subjective when it comes to materials and especially brands... on the other hand we learn why he's thinking and making his product this way... I started to follow this thread to keep an eye on the advertising... but mostly there have been facts and interesting thinking, often out of the box...
I do hear what you're saying... now does air moving at those speeds heat up from friction? I think so... hence the interior material will also make a diff...!?!
I know the product works and am actually getting one! There is so many variables and as I said before I'd LOVE to get air temp and turbulence readings and what they do to engine performance... until then, why take a chance... especially for that price...!!

OK, now we're finally getting some truthful statements.
You're finally admitting that you let things get out of hand when you got off the subject of comparing different types of plastics for intakes, and started bad mouthing metal units with your blatantly false or grossly inaccurate comments like "You'll be able to put your hand on my system after running the motor all day in the summer. Don't try that with a metal system.", and "metal conducts heat, plastic insulates, metal will condensate, plastic will not condensate", in order to try to sway car owners to purchase your product. And it's that type of BS that is an insult to my intelligence, and which I will shoot down from every possible angle.
And finally, your comment "That's like saying the upper intake manifold on my Mustang isn't going to get hot on a 90 degree day. It gets too hot to touch quickly and it flows air." totally agrees with my test results -> The 05 Mustang GT's plastic intake manifold gets much hotter than the CAI, regardless of what type of material the CAI is made from. And hence, the intake air has to flow thru a passageway that's hotter than the CAI, rendering your stance that a plastic CAI remains cooler than a metal one as an utterly pointless waste of time.
thats it now im pissed !!! lol only kidding. seems to me i need to buy shares of happy ice and put an ice bucket on my intake manifold just to cool my car down . hell forget ram air and cold air , im comin out with the all new iced air induction with optional ram ice bucket hood ,( that should be great for the aerodynamic guys) ohh and dont forget the automatic ice maker attachment with direct feed to a 5gallon holding tank in the trunk . and the materials it will be made of wont be metal or plastic cause apparently niether is good enough (ill hav to figure this part out later. probly after my mining crew comes back from the planet goofygoo with the all new building material . hey guys keep this on the hush hush k. dont want the undesirables knowing too much!!) plus the added benefit of my system will be that when your showing your car off ( and there will be crowds and crowds of people ) you can serve them drinks. damn this is the best product ever ,HELL ITS REVOLUTIONARY!! i think ill call it THE SUPERDUPER ICED AIR INDUCTION RAM ICED AIR HOOD SCOOPER !!!! damn im a xxxxxx millionare! eh, who wants a drink? vynle. p.s. k.j., you dont mind if i advertise here do you,thx.vynle.
Hey, better yet, how about TEC's? ( Thermo Electric Coolers ). Remember back in the day TECs were "the thing" for extreme PC cooling. No moving parts to wear out. Uses 12v DC. Could play Doom for hours and still have ice on the processor! Of couse then we would all have to have metal intake tubes.

Jp is not trying to sell a manifold, nor a TB... he just made a system of materials he believes will get the coolest posible air to those parts! Now if that's true (I think it is) the TB and manifold would in their turn be a bit cooler, the air would in its turn be cooler, more dense, carry more oxygen per cfm, alow for more fuel, and a larger, more powerfull burn... all beeing tuned properly!!
Vynle; I'll take one fo your WOODEN intake systems! What kinda power do you figure? Hey, how would it be with a big bath tub of ice in the back, the intake and cooling tubing routed through that, kinda a long way so we need a fan (or more) to move it... wait a minute... think this have been done, not in wood though!!
Hawgman; With ice water IN the PCU we might not need to tune!

Actually, thump_rrr hit the nail on the head.
The air flows so fast thru the CAI that it does not have sufficient contact time with the inner wall of the CAI for any heat transfer from the wall to the air to take place, even at low rpm's.

That is a broad, bold, and not true staement! And you know it!
And again I'd like to point to the affect of the smoother walls inside most non metallic tubes, regarding friction for the speed, temp, and turbulense of the air... and volume again (it has however been proven that volume is not key on slightly modded cars...)
