Dave, I can't see this mod being as good as Dave S's.

 

I don't know, either way I think it is better than stock! Everyone seems to have a different idea for an intake, I just thought I'd add to the process a bit . I have been looking at the way the IDI intake manifold is setup compared to a PSD...Needless to say I'm already thinking of some custom fabrication

 

I spent a few minutes looking closely at the stock air intake on my '92.

It appears that when the hood is closed it almost completely smothers the opening for the intake.

Even if it doesn't completely smother it, the way the hood is shaped the only air coming in would be from the engine compartment or through the approx. 1/4" gap under the front of the hood.

Which by the way is almost completely taken up by the bug shield the PO had installed.

I have looked at all of the RAM air ideas that have been presented and so far nothing seems to fit the style of front end that is on the '92 w/o totally butchering the grille.

Why hasn't anyone used a hood scoop or even an off-road style snorkle to open a bigger hole to stuff air through?

 

Barehuggs, you would have to get rid of the bug shield to do this but you could run a cowl induction setup...Maybe raise the hood middle section 2-4 inches from front to back and pipe the intake to the windshield cowl. Could put a kind of mesh or a screen back there over the opening to keep critters out but if it followed the slope of the windshield with a bit of gap it would work. I have seen drag cars with that setup and it seems to be well worth it...I myself just haven't found the time to start that kind of project

 

I didn't see any pics how do i get to them

 

Here is the link I posted earlier for the ATS setup:

good idea,but the set up I have is a lot simpler and has less air terbulance.I almost droped it down to the bumper but the first time I go rippen through a mud hole or cross deep water its buy buy motor.I'll have to put up my pics.and some from the replacement of the wornout 7.3 my truck had originaly.I have a complet motor is any body it interested.its only got about 450K on it.(rebuilder)

 

Barehuggs,
I have a 91 and I cut away part of the rad support on the drivers side. Since the opening is blocked by the grill I drilled a series of 1/4 holes in both sides of the grill. (to drill the holes I used a sheet of adhesive holes like the ones used to repair note book paper. It made a neat little pattern) I don't have my camera, or I'd show some pictures. the holes look like they belong there. I don't know how much additional air I pick up, but it worked for my tight budget.

 

Barehuggs, I belive with the style of your truck, nothing really "effective" can be done with out some serious surgery....once you install that bush guard, it will give you some options. The biggest hurdle is where to put the piping? One thought comes to mind...do you remember cheapers air mod? Venting thru the inner fender, to the new bush guard or just below the bumper, using a home vent as Dave S's mod....this would give great air flow....like I said, just a thought. lol

My scoop under the hood gets most of its ram air from a scoop I fabricated on the drivers side behind the grill, with an opening cut in the plastic behind the head light. More pictures in my gallery under the same album as the scoop picture.

 

I have been thinking about that too.
The brush guard has alot of area that can hide some mods. That too will need some fab work in order to hang. The mounting holes on the guard are outboard of the frame rails and the current bumper mounts are inboard.

I have the mind for fabrication but not the welding skills or equipment. I am probably going to fab up everything for the RAM air in sheetmetal with rivets and some all weather caulking. And when I have something that works pull it off and take it to a fab shop somewhere and have them make it all pretty.

 

on my ats set up.I brought a 3 1/2in aluminum pipe it gose liek this. A 45degreee elbow then drops to the side of the head.then a 90 degree elbow forward to the front behind the grill.you cant go too low couse of the PS pump.it all ends with a k&n behind the grill.there already is a hole between the battery floor and the rad support.its got lots of air and it aint to low that you'll suck in water if you do a deep crosseing.I've seen a lot of fried motors couse the intake was at the bumper or in the fender.the fender this can be a mess couse of the road dert and debree you tires can pick up.

 

One of my concerns about coming out lower than the grill is water entry.
I live in Western Washington and it has been known to rain here from time to time.
If There was a sump in the system somewhere in the first 1/2 of the path from the opening to the intake and you sized it large enough to hold maybe a quart of water do you think that water droplets following the inside of the tubing would collect there to be drained out by a 1/4" piece of tubing?
It might create some turbulence but should keep water from a heavy rain from making it to the intake.

Cheeper what are you doing to keep from sucking gallons of our liquid sunshine through those scops of yours? For that matter what is keeping the small birds out????

 

You know, I worried about that initially too. The hoses from my scoops both make a semi-gradual 45-degree bend (on a horizontal plane)towards the center of the truck right after they enter the wheelwell. Then they make a sharper 90-degree bend straight UP where they come through the fender liners into the engine compartment. Lastly the stock plastic hoses that fit to the snorkles make a gradual 90-degree bend from pointing straight up to a horizontal plane at the entrance to the air cleaner snorkles.

The aluminum dryer-vent hoses that I used are spiral wound and corrugated to be able to accordion so they can bend, stretch, and collapse - pretty much like the stock plastic intake hoses. These corrugations combined with the bends in the hoses trap the water and keep it from making it all the way to the air cleaner.

I've driven in some heavy rains and busted some pretty big/deep puddles here in the last couple of months traveling at everything from 10-15 mph right on up to full freeway speeds. I've checked the air cleaner repeatedly and it has stayed dry as a bone inside.

As for the birds, well, I can't recall ever having hit a bird in my 30+ years behind the wheel - and even that 420 CID diesel can't suck enough air to vacuum one in! Little suckers are just too fast!

Now this summer, bugs may be a different story. They're dumb enough and slow enough to get hit, and small enough to get sucked in. Guess we'll see....

 

my duckting is so long that the most of the moisture is pritty well evaporated by the time it hit the motor.no to mention being compressed buy a hot turbo.just spend some time looking and thinking of what you may be able to do.and what ever you do be damn shor you use the decompretion valve or you will just sifen the oil right out of your motor.trust me right out the way it went in.mine got stuck shut.
