The need for a better CAI

Doesn't aluminum transfer heat faster than other metals? It heats up quickly and that heat is quickly transferred to the intake air. Or am I way off base on this? I know they use aluminum for cheaper/lighter/easier production.
 
I think we could run the ducting that goes to cool the brakes and bend it up to the air intake,, that is what i have been looking at doing on mine... there is already a nice collector system there in place just need to redirect it up to the motor... and would definitely have to be insulated maybe a pipe with in a pipe to keep the heat out of the intake air...
 
the thing is even doing all this its gonna show the same gains as any there is no real way to dyno....unless someone has a windtunnel with a dyno setup in it....you get what im sayin??? how do we know jmbs doesnt make more power @ 80 mph then a stock intake??? we dont and to say otherwise is speculation so we need to find a way to test what we have then go from there just my two cents!!!
 
That is a good point Dom...would it really take a wind tunnel or would a huge shop fan be decent enough? Would just need a shop fan large enough and strong enough to produce equivalent to slow speeds. At least to get an idea. Then just measure the psi (if any) and intake temp at the throttle body. We have these huge (about 6 ft diameter) fans at my work that can produce a hell of a lot of wind. But, like you said, until everything is proven, this is all speculation. However, I still enjoy hearing new ideas.
 
I would not say its speculation, its a given fact that cold air will increase the hp.. even if you dont see it on the dyno,,, actually who cares if you see it on the dyno,, if you put a temp reader in the air and you can see its going into the motor 100 degrees cooler.. its a fact that your going to produce major hp increase... we just need to get the air up there cold, i think pull off the lower air intakes that go to the brakes, insulate the pipe, and you have a winner...

as well you dont even need a wind tunnel as your not looking for the ram air effect...and you will never get the ram air effect no matter how fast you go.. we'll i think you will get a little less than 1psi at 80mph... we had a member do a wind calculation for us years ago...

so its not about the ram air creating power,, its about getting fresh cold air into the motor... and you could achieve that with any shop fan in front of the truck on the dyno..
 
I thought about using the brake coolers as well but for some reason thought they only came on the 06.....my 06 has the inlets under the bumper grill but the 04/05 models don't have those inlets. Are the brake cooler tubes behind the bumper grill?
 
This is where my brake coolers are hooked up

So are your's coming from here?

The reason I ask is then the routing might be a little different.
 
My 05 has them as well. They all do. I second what the one guy said above about ceramic coating any type of metal tubing just like guys do with headers.
 
Yes the 04/05 are ducted from the bottom grills. I have a brand new set of those ! Plastic is an insulator so it would not transfer heat very well. Would be a good material to use, depending on the temperature and amout of heat we are talking about!
 
I have a pair of junk ones that I was thinking about hacking up to moddify my stock air box.
 
Jmb designed a rad that Prof is trying out. Not sure if it is working for him or not but justin is an amazing fabricator! Should ask him if he has time to look into a shorter rad idea and front shot CAI system. Short rads are ok if you add another pass. Eg, thicker core but shorter.
 
Also have seen the radiator relocated to under the bed. The air flow for the radiator would be from an air redirector. I can see a few good things about this: radiator is now located in a much cooler area, all that weight is now transferred to the rear and it frees up the front end for better direct air flow to the motor. Down sides: not sure how much air flow can be redirected over a radiator in that location, it is a lot of extra piping and fluid. Not only is that added weight, but not sure how the waterpump would handle the extra fluid. Would the air being directed under the bed get caught up (like a parachute) in the rear bumper or is there an efficiant way to direct it back out? Like I always say, I enjoy the out of the box thinking but that is usually as far as I get...lol.
 
Adding my .02 to the OP, can you simply attach a ROE style filter right onto the TB, then seal it off from the rest of the engine bay so it gets fresh air? This would eliminate that 90 degree turn in the intake the only question is where to get the air from.

I'm actually not even sure if there's enough room for it down there without actually having the blower and all that though.
 
Yes they come from the larger intake... but they are down low there is a big metal plate deflecting the wind down to them

you are speculating ken....yeah they drive better when its cold outside but your NOT going to change the ambient air temp....through anykind od cai you know that ken.....we have done a lot of testing on this matter and again your wrong....in front of a shop fan it does not matter what cai no cai or getting a tube from the throttle body and putting it directley in front of the fan it did not change 1 ioda
 
This is a simple process,, I had a pick toyota pick up when i was 16 i droped in a chevy 350 there was no room for a rad in front unless placed infront of the rad supports and even then it was cut into the back of the bumper to create room for even the smallest rad.. so we then put a 2nd large rad under the bed with a fan on it no cooling intakes.. just the fan and the temps droped from 250 to 180 and there were no problems.. a vary simple project ....

no producing a kit that people can just bolt up is not a simple and just welding it up on sight.. but it would be done.. and would be no problem

thats exactly my point,, it wont change as there will never be enough air pressure to create that change at normal speed.. there was a post before that shows at 80mph there is 1psi of air pressure.. and 1psi of air pressure is not going to do much of anything for you.... so my point is...

cold air is the fix.. vs hot air.. and everyone knows for a fact.. that if you have cold air going into the motor that has not been super heated by your headers and engine and everything under the hood... you will create more power...

some kind of fan pulling the hot air out from the engine comp......you act like everything is sealed tight you have alot oh air flow going though the engine comp.....but what about actuall wrapping headers and such to get the eng com coolerbut if you look at jmbs it has a box so your just not pulling cold air in ....what about putting a hole in the bottom of the box and having a tube go fro the lower valance to the hole in the box cold fresh air simple simple simple
