Think Hydro dynamics if you must. Yes the bends in the pipe will restrict airflow, but when you have air moveing at high speed entering the intake of the snorkel, and forceing agaisnt the air that is slowed down in the tube what will happen? Will the slow air cause a space fluxed, and reject the other air sending the snorkel into the past? NO! its a simple theory.... Air will push past the bends, and continue to flow nice and fast. If its such a bid deal stick a peice of 3" PVC out the front of your jeep as a snorkel.

As far as building your own snorkel. I am going to be building one and hopfully if I can designin it well enough will go into the cab up the front pillar ( Made from metal) and have a small scoop on the roof. I had the idea play GTA san adreas modding a car, and am still trying to design it which is proveing rather hard lol.

Another point worth noting is that any of the snorkel manufacturers will point out that, while their product can make deeper crossing possible, the main point is better quality (cooler/denser and CLEANER) of air.

Snorkel is better for short and long term engine performance almost every time, without question.

But, I wasn't equating "cooler air" to "more air" as in density, although you are correct (I know what you're saying).
I'm actually saying that you'll get more air pushed, with more force, via the snorkel, than you would with the factory air inlet horn just chilling under the hood.

Typically to get cooler air you segregate the air intake from the engine. To pull cooler air. Cooler air means more power. The cooler the air the cooler the temps in the intake. That means you can dump more fuel in. More fuel = more power. Escpecially with diesels. The object is force as much cool air and fuel in as you can.

In theory since the air is being pulled from outside, being the the ambient temperature is cooler than under the hood, you should notice better throttle response, and improved mileage with the snorkel. Provided the air flow is unrestricted, and the piping is allowed to get to warm.

Then again I believe that you could always make up power else where if you were really worried about losing any....

Exactly.
People equate the air in the snorkel to a ball that is having to change direction at each bend. Nobody takes into the account that that it is a constant flow...more like thousands of balls () being compounded into the tube, one on top of another.

While I see your prespective, air like water will find it's way regardless of obstructions. Hydraulic Pressure is far greater than Air Pressure. You want the air to have velocity while entering the engine as this helps the combustion process. Think of a shop vac for instance. I You have the smaller attachment on increase the sucking power of the vaccum. This principle can be applied to intakes. Intake piping that is too big will hurt performance. It will fail to force the air into the engine with enough velocity. It'll be like trying to breathe 20,000ft above the ground. The air is there, but the vehicle just won't be able to breathe it in efficiently. Something for you guys to think about.

I'm no professional, automobiles are only my hobby. I do however build some pretty quick cars..

I agree and disagree... since Q=V*A... or Flow Rate = Velocity x Area

What you want coming into the engine (such as superchargers) is more Flow Rate. What you said was that increasing Area will decrease flow rate and supply less Volumetric Air. Actually, the flow rate would remain constant even when the Area (size of pipe) is increased and Velocity is decreased.

It is all going to bottle-neck at the throttlebody anyway...
