 Subject: "home brew" RAM AIR-TRUE COLD AIR INTAKE
IP: Logged
Message:
Just wondering if anyone else has tried this??
What I am working on and is 99.5% complete is an intake that not only pulls air from the outside of the engine compartment but also is a ram air intake by means of removing the plastic piece that is to the right of the radiator, then directing that air into an enclosed K&N filter.
I am aware of the fact that it takes something like 6-8psi in order for you to see some actual improvement from "Ram-Air", but I am hoping that the vast knowledge on this site will help me realize whether or not I am wasting my time or not.
Thanks for any advise/input
I own a 2001 4.7 QC

i have done the home made intake and did the same thing. i didn't place the filter in front of the hole, but what ever cold air your taking in will help.
im going to cut a hole 3" were the horns are located and stick a pipe down there with a 90 degree bend to point the open right in front of the fog light. so i will be sucking cold outside air. than make a air box out of aluminum that will have pipe to suck all kinds of outside cold air.

Actually I didn’t place the filter in the hole either (it is entirely too big for it to fit where the plastic piece was) and on my truck the horns are on the opposite side of the radiator. I wish I could post some picts so that I could show you exactly what I am talking about. If I am not mistaken the only way to post picts is to become a member and I would of had been a member a long time ago if not for the inability to use my paypal funds to pay for it.
Anyways, I used 20-gauge metal and contoured it around the entire opening and flared out the fwd end (the end closest to the grill) to capture as much air as possible without obstructing the radiator fins. The other end directs the air to a box about 14"x12" the element side of the filter sits in the box with only the opening of the filter sticking out of the box. Then attached my "homebrew" intake tube onto it and the other side to the TB. The entire setup is completely sealed so as to help with the Ram-Air function of it.

WOW, didnt think about that! It is easy to see that as I am driving if the air is getting "RAMMED" into the intake box then the water is going to do the same, once the filter gets saturated with water then it is surely going to get into the TB. There has got to be a way to keep the rain out of the engine. How do the Ram-Air hoods do it?

The older (68-69) ram air carburator pans have a ridge rolled into them. Around this ridge is a series of small holes that drain water into short rubber tubes. These tubes carry the water down around the block past the exaust manifold.
The '70 superbee I had, had the (rasin bran) two scoops on the hood. They also had some little rubber doors that was controled by a cable that was mounted to the dash. As per the OM you were supossed to close the doors in the rain. DUH
I havent seen some of the newer Dakota ram air hoods, but I would hope they have a simaler set up.
Hope this gives you an idea of how it works.
Oh you could also try to find photos of an air grabber style scoop from the late 60's early 70's.
