ram air intake idea

[Big Red Monster]

I kinda stole this idea from bakers design but i have an idea to do it differently. what if we take the air induction tube used to feed cool air into the air box on the 90s f series trucks mount that under our bumpers and run a duct from that piece to the air box? bakers way is good but for those of us who have factory fog lights we need a different route. anyone else think this is a good or bad idea?

Only way to find out if it works is to try it! I think that anything ram-air makes a difference as opposed to drawing from the fender. Now I have not looked at the bay with this in mind, but I imagine that it would take some creative thinking to feed the tube up through the engine bay and avoid hot radiator hoses, etc. while still having wide enough pipe to feel a difference, but if it can be done, it would be really cool and different.

what Imma do is try to get the flexible drain pipe tubing, cut a hole into the black plastic fender skirt and run the duct right below my driver side fog light, radiator hose would be avoided, only problem i see is if the tire is going to interfere. Im going to the junkyard in the morning, gonna pull apart an expy or f150 and see what kind of space i have to work with and then i will let everyone know if im going to attempt this

i actually think we have enogh space to do this seeing as the gotts mod utilizes that big hole in the fender, all we need to do is run a duct from that hole and we should be good to go

if i wasnt in cali and i could do anything i wanted with the intake i would take the intake and bend it up and into a cowl style hood and draw from there. almost like an S shape the bottom being the TB and top the filter.

I actually looked into this idea of RAM intake as well. There is plenty of space to run a tube down to the lower grill/fog lights area. It might make life easier to remove that fender skirt. I was talking to my friends that are all going to school for mechanical engineering as i am and we are all into cars. We all are part of SAE Baja. RAM air is more going to help cars with turbos and superchargers. The gain would be pretty small at low speeds so the gotts mod is your best bet. High way speeds you may see an improvement in efficiency so its worth a try. I would try mounting the intake of the RAM system in one of the gaps to the left or right of the licence plate bracket. Mounting towards the black ground effect may cause it to be in a spot where the air flow is forced away from your intake due to aerodynamics of the bumper. Definitely keep us posted on this project because i am really curious to see how it works. If it does turn out to be better at high speeds but not at lower i may work on a hybrid system that can switch between RAM and Gotts with a flip of the switch plus u may not want the RAM in rainy weather. Be sure to add a water catch in your RAM tubing. This can be done by making a section of tubing dip down similar to what you would find in a sink and add a small hole at the base of the dip to let water out.

Big Red: Also what are you using as an inlet for the tube or are you just leaving the intake the pipe. I am thinking of casting ABS intakes for the ducted brakes i wanna add but if you find something already made or easy to make let us know. If that RAM works i will prob make intakes inlets for those too.

well as the intake duct im using the inlet to draw air to the airbox that was used on the 90s f series trucks and broncos, the duct fits perfectly, i can not mount the duct by the liscense plate due to the fact that i have an air compressor mounted behind the plate and amber lights next to the plate, so i mounted it below the driver side fog light. now the duct i used wasnt a perfect fit from the start though, I had to heat it up and bend it about 45* from its original position, also had to cut part of its original mounting tabs off. I bought some 4 inch diameter drainage tube from ace hardware and i will be using that to duct it to the intake box so i will be cutting a hole in my fender skirt. tommrrow i will be running the duct work up to the box because i have to work today unfortunately lol. ill take some pics when its all installed.

Sounds like some progress is on the way, keep it up

update: I decided i dont like the duct below the bumper so tommrrow my black ground effect piece meets the dremel with the mini circular saw blade, going to make a notch so it looks like it came with factory ram air

 

[Big Red Monster]

Well it is done, I did not cut the bumper however due to a few reasons, one is I may not keep the duct because well it just looks ugly and two the maze of plumbing behind the bumper sits a little to close to my tire for comfort and I may end up just leaveing the top hose from intake to fender well in placw. Performace definetly changed, acceleration is quicker and I maintain a speed of 40 mph at like 1200 rpms. So yes it can be done, took me eight hours to get its done but it was worth it. So to anyone wanting to do it I say go for it. Pics will post as soon as my phpne cooperates.

We really need an android app lol

i do have one concern with this. should i be worried about sucking water/snow up into my engine when im driving, or at a car wash for that matter?

 

[splintrcel]

does ur duct run in a direct path to that hole in the fender? Cuz if it does then i would say yes, water will get sucked in. Basically you need to add a dip in the path so there is a low point for the water. Almost like a sink trap. This will hold the water from getting into the rest of the intake and engine. Make a small hole at the base of this dip for water to exit.

 

[FordandPolaris]

Do you have pictures yet?!? Mine runs 40mph at 1600 rpm's so if it makes that much of a difference, sign me up... Could be different gears and what not too.

 

[Big Red Monster]

Mine has a slight dip so I may make a hole in the slight dip, the inlet duct has a 90 degree radius so I would think that helps. Ill try posting pics to my album

And at fordandpolaris. I too have 3.73 gears

If u want to see pics of the setup look at my albums

update: splintercel you had to jinx me lol. anyone thinking of doing this be warned the muthaf**ker will suck in alot of water easily and i had a "drain'", so i didnt keep it on as I do not want to hydrolock my engine, instead I ran the duct right below my headlight and aimed down, it still helps with power because its getting more air from a cooler spot and it dose not suck in water. I really wish banks or k and n would devolop a proper ram air keit for these trucks. right now im averaging 12.5 to 13 mpg in town- and i live in chicago

 

[splintrcel]

I will give the ram a shot once i get a hold of some ABS plastic. I am gonna cast two intakes for cosmetics and see what i can do about the water trap. RAMs do suck in the rain so sorry for the jinx lol. I just need to make sure i get everything all set before i tackle it. I am gonna suck air in through the holes left and right of the licence plate. I am also gonna add removable grating to catch bugs and what not. I will post pics of what i am working on. Did u end up removing your fender skirt and if so how did u go about doing that?

 

[Big Red Monster]

Yea I want to see what ducts u.make. To remove the fender skirt simply pull out the black push in rivets and then take out the small screws along the edge of the fender, takes about 5 minutes to do so
