Ram air idea

[Hohn]

Well, I had a stroke of near-genius and thought I would run it by the gang to get their take. After seeing (and loving) Whitmore’s RamAir intake setup, that got me thinking about other ways to do ram-air. (that’s the perfect name for it, don’t you think?)



Why can’t you take 5” exhaust tip and shorten that to use it for your ram air intake duct? OO! What if you took two 4 or 5 inch tips and made dual intakes? You could make them look like fangs on the front! Haha. Imagine making an intake that was basically the same design (different routing) as the exhaust system only with a filter housing in place of the muffler!



Why is there no market for Mandrel-bent intakes?? Imagine opening your hood and seeing an intake system that you could SWEAR someone made out of a chrome stack pipe! Chrome plated filter housing…. . Chrome steel tubing running to turbo…



If I tooled up and made a bunch of these would anyone be interested in buying? I would have to get the setup PERFECT before that would go though… My own standards are higher than you would ever expect. That prob means I will never get it to market because I can’t get it good enough.



I will keep you posted. I LIKE this idea!!!

Hohn,

You can do it baby, I Love It, the hard part would be to find a path for this LARGE pipe, right now the only path I can think of is right where your OEM wimpy horns are mounted.



Keep thinkin Dude... ... ... ... ... ... Kevin

hmm..

. . Now I am thinking that you don't want to use an exhaust tip-- it won't capture enough air. I am thinking about making a duct that mount about where the OEM airdam would go. It would drop down about 3 inches, and be about 24 inches across. That would scoop more air into the 4"-5" tubing.



How to make the duct though? I am thinking my best bet is going to be carving a mold out from wood and then laying up fiberglass. I think the regular fiberglass kits at the auto parts place would be fine.



Where can I get plate aluminum? I want to be able to have someone weld up an aluminum filter box. Then I have to rig up a flange for the tubing to connect to.



Dang I wish I was home!! I need it to eyeball the clearances. I am stuck in Oman for another month then I get back to my truck!



No doubt I will have to move the puke bottle and such like you did. It's sad that the most space seems to be along side the exhaust-- running the intake plumbing next to the exhaust defeats the whole purpose of having a cold air setup!

Twice pipes

You could always do a 5" stack setup only have one for exhaust and one for intake, the intake tip could be pointed foward

Hohn,



Keep us posted. It's a great idea!! I, for one would be interested!!!!!!!!!

 

[bighammer]

How bout a hood scoop on the roof of the cab? You could cross a really deep river then. (as long as your windows are up)

I've been thinking along the same lines. We are tearing out an aeration tank at work, with a little dumpster diving, I can come up with 8", 6" and 4" stainless tubing... . I just havent figured out how to build a filter housing out of the 8" and pipe it with the 4"

Mainly because stainless is such a bugger to work with

that idea is what i have had in my head for a while now... i'd like to someone do that

Remote Air intake

Some of the older big trucks had remote air filters, some on the outside of the hood and some on the frame behind the cab. Using one of these setups with a bent pipe to the turbo would be easy. Either make a filter housing or spend some time in a big truck junk yard, you should be able to find one. Be sure it is a dry filter housing. Mount it in the bed, and run a intake pipe above the cab. If you use a curved intake to the front (Ram Air) make sure there is a way to keep rain water drained. Most of the larger ones used 5 or 6 inch intake pipe.

Don't think down low is a good location, seems like it would turn into a dirt/water scoop. Another problem, that racers take into consideration, is the heat coming off the asphalt, I've heard on a warm sunny day the temp 12 inches off the roadway can reach 180°.

 

[esommer2500]

Wasn't it the older style (early-mid 80's) cab-over International's that had an intake box that came up the back of the cab and had a 'ram-air' lookin box on it? This could get interesting...

Ifflem: You forgot winters in Montana, remember the snow particles blowing over the top of the road all winter long. A scoop below the bumper will pack the air filter with snow. Even some of the 80's Fords had trouble with snow pack and inlets in the grill.

 

[Power Wagon]

Just don't do as me.



Back in my younger days me and a bunch of my friends were out bombing through the desert in Utah. We crossed a small stream. Well, I thought it was a small stream.



Instead, it was much deeper than 2-3 inches I thought and I sent a wall of water up over the cab and DRENCHED everyone in the back.



Didn't get anything under the hood, though

I bought the dam-air Spoiler for the front end. It has a scoop for air entering through at least a 4" pipe. It has a thing to modify the airbox so the air goes into the box. I had taken the snorkel out of the airbox and blocked it off so i would get full ram air. Seems reasonable huh? well it made so much restriction that at slow speeds, it pulled the restriction valve down almost all the way... . ??? so I took the blockage off and insulated the opening of the OEM hole from the heat of the engine compartment. So now I don't have a real ram air system uless at high speed it might... . but at least it is cooler dense air and that should help.....

In another life (in aircraft), we had a ram air scoop that you could electrically extend whenever you wanted it.



In town and not under acceration the conventional air flow is probably ok (but I do not really know),



On the road or when under heavy acceleration (pulling etc) you could extend the ran air scoop. The faster you go the more ram air. Maybe even mount it to the filter side and mount it permanently. No long loses, do not have to find routing. Go directly straight out where the snorkle to the existing air box is. Something like a boat air scoop for the bilge blowers?



Have zero idea how though.

Break out the sazall and get after that front fender. .



Why not just some type of hood scoop?? Someone posted on one they where using that was removeable so you could turn it around when you did not need air. How about a big hood scoop with a little flapper door? Open it and ram the air in, close it and run as stock.



Someday I will get hood with a scoop on it and that is what I plan on doing... untill then the ole BHAF will have to do.

Wish we had a place for those big stainless Vortox intakes the Peterbilts use! $1,500. 00 each, ouch, no wonder they use puzzle lock nuts to keep 'em from disappearing.



How about a drag race style scoop on the passenger side of the hood passing through a huge hole in the hood, sealed to and air box opening with weather stripping? I've seen some low profile scoops with big openings.



Back to the Vortox! Would a small one fit if you hacked a cylindrical chunk out of the fender? Maybe half of it could extend beyond the bodywork. Still would not stick out beyond the training wheels on a 3500

 

[NVR FNSH]

Don't the Izusu or Iveco cab-over box vans use a black plastic intake scoop up over the cab?



Brian

 

[Whitmore]

Volkswagen aftermkt has those nice plastic little scoops that they run ontop of the cab too... ... ... ... ... ... ... ..... interesting

A couple years ago I had a chance to go down-under and practically everything with locking front hubs had something like this...

At first they are really obnoxious, but they grow on you after time.
