do you actually understand the fundamental concepts behind the article? Think basics....what causes combustion? air and fuel. how do you make more power? By having more of the air-fuel mixture. Since you can add fuel by using larger injectors and the such, that part's easy. Well, how do you get more air? Since air occupies a certain volume at atmospheric pressure, and a small volume at higher atmospheric pressure, you can fit more oxygen per volume by pressurizing it. The OTHER way, is to use colder air, since colder air already occupies less space, i.e. the air is denser.

Obviously the ideal, is to have pressurized cold air, but if you're saying that the highest atmospheric pressure zone is better than having cold fenderwell air, then more power to you.

 

The best material to use is whatever you're happiest working with. Air is moving through the air box too quickly for it to pick up a enough heat to matter.

Even though it wasn't really necessary, I used adhesive insulating material on the hot side of my aluminium heat shield. It was just stuff I had lying around.

The following quote could be the dictionary definition of "way wrong"...

If it helps your engine breathe better, how could that not help performance cars? It doesn't matter whether the engine is a "performance" engine or not, or whether it's turbo's or not, the effects of air temp on engine performance has been known, understood and taken advantage of for many decades. Cooler air makes more power. Simple as that.

That is a good article, but it doesn't back up your silly claim about air temp at all.

That's not what it says at all. If you took the word "only" out, you'd be correct, i.e. "the intake adds performance gains if it is under positive pressure".

Actually that method works fine, and is a hell of of lot easier to do on an FC. While the theory in that article is completely valid, in the real world it's not always practical or achievable. Have you done it to your car?

Actually that would be cue Evil Aviator...
