Default cool intake/exaust?

i was thinking if this was possible/worth it----> taking an intake pipe and surrounding it with another pipe of a slightly larger diameter and shorter length(to allow clamping), sealing the two pipes together at both ends, drill a hole and fill the space between the two pipes with some type of coolant. this would keep almost all engine heat out. Also i was thinking that it would be benifical to box off the exaust headers and surround them also with some type of coolant.

is this just a bunch of extra weight or what?

Yes it is extra weight, but maybe not too much on just the intake. Unforutnetly, if you don't cool that coolant it will just heat up and then act as an intake heater . For this to work, you'd have to plumb in some tubing to run the coolant from the radiator into the intake cooler then into the engine as normal. This may or may not cause problems with coolant flow, but it will only cool the air to the temp of the radiator which may be _higher_ than ambient, so again, heating the intake charge. The exhaust would be just as hard or harder.

But, there is hope, if we filled that space with a good insulator, which is much lighter, it would keep heat in the exhaust and out of the intake, but these ideas are what you might have had in mind to improve.

So, yes, we could wrap the intake with coolant, but it needs to be circulated and cooled somehow

The problem with this is simple....Any sort of coolant will absorb the heat yes, but you will not see a noticeable improvement in performance to warrant any device like this. The single improve that can be done is make the incoming as cold as possible! Cold air is denser than normal (room temp) air. Therefore, more actual air gets into the engine & hence more HP is gain through combustion of that air!

I've heard some people talk about a similar subject and in the end just getting a cold air intake was the best option.

I've always toyed with the idea of a freon-based intercooler. I'm sure others have, also, but what do you peeps think? With the right part, I think it could be done.

I started working on this idea a while ago. I would not use it on a N/A car though because the air is rushing too fast to be cooled by the intake. NOW, for a Supercharged or Turbocharged car, this might help keep temps down used in conjunction with a intercooler and probably lower temps a little more. But I am working on a design similar to this idea but for Eaton'*. My design is meant to be a less than $1000 dollar intercooler that works as well as a air-to-water and works on all Eaton/Whipple/Kenne Bell superchargers. Anything that is roots style, screw, etc.
