my guess is it has something to do with a lack of a plenum that helps keep the air cool???

 

Would heat wrap like whats used for headers help keep heat out? I know its meant to keep heat in around headers, but just trying to think outloud here.

 

I had thought of that too. Kinda wondered if there was some kind of ceramic coating that could be either sprayed or even brushed on.

 

My problem is the air temp stays cool while driving, but if I go park it somewhere for a couple minutes, the tube heats up from all the engine heat and then the temp is atleast 20-40 degrees above the outside temperature. The intake temp sensor will read about 90 degrees on an average day or night.

Also, Im wondering if I should remove the insulation on the bottom of the hood. Im guessing its only true purpose is to keep the engine noise level down?

 

With your color, it might help. I don't think it would be wise for my black hood. That might keep heat away from my motor.
I also like the idea of ducting the intake to behind the bumper like the Banks system for diesels. It looks great in my head.

 

Im looking in to doing that this weekend, but youre so crunched for room by the air box. I would use PVC/ABS for durablitly reasons, but theres not a whole lotta room to insert a pipe in to that air box. Im thinking I might be able to get a ram air set up though if I drill through the metal plate below the air box, and put it through there and in to the bottom of the box. Im not so sure that Airaid using the stock box bottom for their CAI was such a good idea :/

For the ram air scoop, I think Im going to take the 3" pipe that I use and heat it up with a torch to flaten it out, so it will fit in the little bumper slot next to the fog light.

 

Sounds like it would work. Let us know how it works out. I think, if I can talk with my uncle, I can get some kind of duct work rigged up.

 

Yeah, my other idea was to just run the 3" pipe in to the air dam for the cooling system. I was only under there for a couple minutes thinking about it, so Im not sure if theres enough room. If anything I can do a 2" pipe too. Its just a cool air supply, not the actual intake to the engine.

 

rengnath, I removed the insulation from my hood because it was ready to fall off anyway. Makes the motor sound better (louder). Hoping the heat does not blister the paint over time. Are you sure that running pipe all that distance (to the air dam) would not have a negative effect on performance? Plus you would have to be real careful about water getting on/in the filter in that location wouldn't you?

 

My insulation is hangning kinda low too, so Ill probably just end up pulling it off. IMO, the insulation probably doesnt do that much once youre truck is parked. The heat will eventually get through the insulation and just heat the hood. Idk?

Heres my thinking on the intake, and I may be wrong so PLEASE correct me because I am by no means "a professional" ....
The Airaid CAI sits on top of the stock air box, with a shield that "seals" with the hood. The seal isnt going to be that great so the air that will be sucked in will probably be hot air from the engine compartment anyways, except for the little affect that the air that is sucked from the fender will have.
SO, my idea was to run 3" galvanized heating duct from the hole in the air box to right below the bumper between the fog light and the license plate. There isnt enough room to play with the air dam so thats out, the only thing I can do is put a 3in pipe right at the bumper level and air will be pushed up the tube.
Next, the problem of water in the filter. I questioned this too when I first thought of it, because the pipe will be facing the front of the vehical, and during a rainy day Im sure water will make it inside that pipe. The pipe will never be submerged in water, just the mist from the road and what ever drops it can catch. There will be no suction on this pipe because there will be no seal that will allow the air intake to actually use the pipe as a vacuum. Any water that gets in to that pipe would have to be pushed up that pipe, become air-born in the air box, sucked up by the air filter, saturate the air filter enough to actually generate water droplet inside the tube, and then if the heat doesnt evaporate the water inside the tube before it hits the throttle body, then there may be a problem. And for the piping; the pipe will be that duct piping that has the 4-5 different sections so the pipe allows you make many different angles. The pipe isnt perfectly smooth inside, so a water droplet would have to take many routes to actually make it up the pipe. Also, the tube will have at least 2 60-75 degree angles so thats more resistance too. After that explanation, what are your thoughts? Please correct me on anything you have doubts on, as I am open to critism and wont take offense. And sorry for my long list of ideas.
