good idea but has some flaws...like water, mud, small animals crawling in.....not trying to put down the idea by all means...cause i thought about it to.... which truck do you have.....

 

when you do, drill a hole in the bottom of the pipe so that water can drain out as neccesary..Also ,put some type of mesh grill so that animals will not crawl up into the pipe and into the air intake system. As far as water going up from the fog light all the way up into the intake system will be very hard to do unless you are going through some canals. just leave the filter where it is not and run a ram air sysem do there and let the ram air hit the new filter and it whatever water does make it up will get absorbed by the filter.

 

you forgot mud...lol

 

the volant ram air is right behind the grill and partially blocked by the cylinder next to the radiator (keeps small animals out).

 

I dunno if you will get any appreciable pressure build-up from the ram air setup. Air is very light and speeds are low. You will probably lose all the gain going through the filter.

 

speeds are too slow to see any gains from the 'ram' effect. any gains from this are from the cold air effect.

 

which truck do you have.....

Got an '08 CC.......My truck will probably never see off-road. I know from working on streetbikes that their ram air is much smaller and does work the faster you go. Maybe it will help high speed MPG? I might look into it futher if no one else has.

 

Ive just made a ram air induction kit for my UK spec Navara 2.5 Turbo diesel.

Got all the bits from ebay at a cost of around £40 or $80ish. 76mm aluminum pipe to mount the air flow sensor in and to join the stock pipe from the turbo to the air filter.

the unit draws air from inside the front wing which is where the stock air box drew it air from. works really well as my truck has also been chipped, sounds really meaty as well

 

I am confused by the use of the words "ram air intake" in this discussion. The meaning I've always thought this meant was to point the intake in the direction of the truck's forward motion. Truck velocity would "ram" the air into the intake. Technically, the velocity is converted to stagnation pressure. Without the intake pointing forward, how is this design a ram air intake?

 

done it....2 ways http://www.clubfrontier.org/forums/f23/jerry-rig-ram-air-17457/index2.html , one like Pro 2x mention, where I directed air from the fog opening to Airaid air box (not really ram air) but turned my CAI set up into an actual COLD air intake, and not just some warm air under the hood intake like most everyone has. Not long after I installed it, we had 4 inches of rain fall in just a few hours...I successfully drove through about 24 inches of water while rescuing 5 different cars and trucks that night without any water going into my air box. This was due to the combination of how the plumbing ran up to the air box effectivly using gravity, and the fact that it was not connected directly into the cone of the filter. To keep the truck asthetically pleasing to the eye and not just have one side uneven, I added a second similiar set up to the passenger side that ran plumbing to the throttle body, since I removed the HOT radiator line running into it which while at opperating temps would negate the cold air that just entered and heat it just before it entered the plenum.
*[ the draw back to this set up was gas millage]*
After fuel prices went through the roof, I had to remove it. In the cold winter months I was actually getting my intake so cold that I was gaining ponnies, but at a price. See the not so convenient thing about the ECU is that it can sense these changes and change the A/F/Ratio adding more fuel for essentially more air.

2) The second option Im working on was a more traditional ram on the hood. I purchased a fiberglass set up from AC(automotive customizers) which I then mounted with the 3m double sided tape and the screws provided. Then I took the leap and cut up my hood and removed the mock plastic pieces that prevent air from entering the fake scoop, and it worked and looked good, (IMO at least). Ive been driving with it just pulling cool air into my engine compartment and removing warm stagnant air away from the headers and plenum. Im still working on a design that will mount on the underside of the hood and will direct some of that air into my box. As well as using fiberglass bondo to mold the scoop into the hood permenantly. But like I mentioned ealier, I would like to get a chip or the guys from Austin to grab my ECU by the balls and take control of the A/F/Ratio so I can have some useful gains and reasoning to this maddness.
