Default True forced induction hood scoop

So I came up with this idea a while ago because the only kits I've seen are not really cold air intakes and cost way too much. I'm making a shaker style hood scoop for my jeep I'm almost done just need to make a few more welds before testing. I just want to get some feedback on this to see if people would like to see this on the market. I'll post pics and gains soon.

Wow, deja-vu. I was just reading some articles on XJ CAI's and came to the same conclusion. The majority are warm air intakes or overpriced. I was doubtful of the shaker/ ram air design on a 4x4 because of rain/mud. But, I started looking at some of the F body ram air hoods and those guys run their vechiles even without baffles in the rain and just rely on the filter to keep out water. Everything I read basically says it isnt a problem except in the worst super heavy rain...I guess the solution they use is a removable baffle of some kind, although I havent saw one. They also try to keep the filter above the hood defilade. On a side note I also read a "4.0 myths" artice by JP Mag. If memory serves they figured about a 1% increase in mileage and around a 5hp increase. Not to mention (and I will probably screw this up, but someone else can correct me) for every 5 deg drop in air temp you get another 1% increase?...Lastly, I dont know how OBD2 would like ram air very much?

Well I thought about the water issue and it turned out to be a lot simpler than I thought. Since the top unbolts for the air filter you can just turn it around now you have cowl induction.

Dunno how feasable it is to stop on the Hway and unbolt anything. I know a few fellas with WS6 Trans Ams that have a pretty simple cables running to their baffles. It would have to be easier to fab something like that up in an XJ too.

Agreed. Some type of blocker/baffle would be good. or at least some kind of plate that could just be slid in to block the rain

Well in the original mock up I had that but then I realized that one it would be the only round thing on the exterior minus the wheels. The second is the circle entry point cut down on the flow of air compared to a solid square entry and lastly the mechanical baffles would just add one more thing to break.

IMO the baffles can come at a later date. Post up a picture, because it might be easier to think of a baffle design when we had design contraints.
