I Love hood scoops, I haven't owned a vehicle yet that did get one installed. I will say this before I continue. The following is on my Mudtruck, it gets used and abused and wasn't built to win best in show.
I wanted to accomplish two things, go through deeper water/mud and be friendly to the motor. I couldn't imagine running a marathon while breathing through a garden hose. I couldn't see installing an extra 5-6 feet of tubing and bends and expect my motor to basically do the same thing.
Here is what I did.... 4.0power87, not trying to steal your thunder, just giving you some ideas even if it's what not to do.
I took the original air box and flipped it upside down. Cut out what was the bottom and fabricated my own scoop. I mounted it above the valve cover so it would be centered in the hood. Uses stock clips and air filter element. Jeep has been through major storms with high winds and down the road at 75 mph with no issues (will the clips hold etc.)
lessons learned, don't block oil fill and if your scoop is huge your hole in the hood will be even larger.
If the weather looks bad I just unclip the scoop and reverse it and the same if I fear water splashing over the hood during a crossing. Quick and simple. I have run it in light rain with no issues. If the element gets soaked however, then it acts like a choke.
Any questions or other interests I can do a build thread I guess.
I am curious to see what your finished product will look like 4.0power87
2 pics to show the forward and reverse set up.

as i stated, my scoops are just for cooling down the engine components as my intercooler, and with a new scoop on the other side to cool down the turbo and bring cool air to the intake, i dont believe that there would be that much resistance driving at 60 or 65 that is the most i drive my truck , to have a forced induction youll need a turbo or supercharger no matter what you install on your hood, otherwise your vehicle will be a naturally aspirated engine!!

well , at the rate us dollars are on my country they could be at least 88 us , and 31's where about 95 , i really loved the idea of getting 31's but i had to cut fenders and didn't wanted to get on to that mood , im still having issues with the steering, whenever i turn, the tires rub on the lower control arms so im trying to buy some spacers, i tough if this is with this small tires i wouldn't realize the pita with bigger ones...
