IT seems a lot of folks have done some pretty extreme mods to deal with heating issues. Some of the mods are really cool and look good, too. I see hood scoops of different kinds, and other sorts of things.
In homebuilt airplanes, and just planes in general, we deal with heating issues since most piston powered aircraft engines are air cooled. We have to find a way to duct air around the cylinders and also to bring air into and exhaust air out of the cowling. I don't know if this is true with a Jeep, but in a plane, exhausting the cowling can sometimes be as important as scooping air in.
One of the most popular ways to move air from outside the airplane to inside is the NACA duct. It's also used extensively to bring fresh air from outside into the cabin. Small planes are rarely equipped with A/C, so outside air is important. These NACA ducts are also really good for this.
Okay, so what the hell is a NACA duct? Well here 'ya go.

And you can buy them, but they are a little pricey.

So what I was wondering was if anyone had used these in the hood or maybe even the inner fenders of an XJ for cooling or venting the engine. IT would be quite a bit of work and expense for an experiment, but I have yet to see pictures of these imbedded in the hood of anyone's XJ.
If I have any heating issues with my XJ, I might give this a whirl, just to be different. On the Wikipedia page, there's a picture of a red sport's car with NACA ducts incorporated into the hood. I think it looks pretty sweet and not something you'd typically see on a Jeep.
Thoughts?
