Default CAI cooling...

Ive gotten to thining and brainstorming again, tell me what you think.

Ok so say you have an aluminum CAI intake. I have heard that they get a little warm over the engine. So that got me to thinking (collective groan here). Howabout watercooling the intake pipe. This could be accomplished many ways but i had two ideas. have the 3 inch pipe for the air intake, then get say a 3.5" pipe to fit overtop of it with the space between them sealed except for the spot where you pump the water in (at the bottom near the filter) and out (at the top near the TB) and then through a small radiator mounted elsewhere in airflow. Then this whole dual pipe would be wrapped in insulation.

The second idea i had was with say, .5" copper tubing wrapped around the CAI pipe and insulation over top of that. Then through a radiator.

Both of these would be powered with a small-ish electric waterpump that wouldnt draw too much from the alt. and yet would be enough to efficiently cool the pipe.

Would this have any effect at all? because the air gets warmer closer to the TB so might it negate that effect? Or am i just putting too much effort into something that doesnt do anything?

it might work or it might make it worse it depends on how well you can mange to cool down the water, isnt there some kinds gel that could be used also? not my area of knowledge but sounds like it might just work

if you wanna cool it that bad, use the AC system somehow, because you can get it colder than ambient air. I would say just wrap the pipe in insulation and see how that works. Remember you are actually pulling power from the engine when you run that motor, while insulation would only help if anything.

I was worried about the ambient temp thing too... Im just throwing it out there, not saying that i am goign to do this, but when you pull all the small not necessarily great ideas together i can lead to one huse awesome idea. I am just provoking ye wee imagination...

And the electric motor i woulda used would have been much less draw on the motor than the A/C pump is. Because i remember hearing that the draw on the engine would be more than the overall gain of power.

if you had a poweradder like a big SC and heat was a problem then the AC idea might work, you have it on in the summer anyways. I think the F150 Lightnings use a system like this for their M112.

I was thinking liguid nitrogen (not sprayed into engine tho). If its in a sealed container how long does it take to get warm or does it even? And you would have to take some precautions because your intake temps would be im guessing about -100* F And that causes the freezer condensation effect...
