with the safari snorkel do you have trouble routing the hose over to the pass side? Since it goes towards driver side now... any pics of the safari setup - razors looks sweet!
Gumby said:On an unwaterproofed rig you don't need to get to the bottom of the headlights. The fan can throw the water around and short your ingition system. I have had mine pretty deep after waterproofing the engine and it runs fine with the headlights underwater.
Beside the air intake being high enough and sealed, what are the other major things to do to waterproof your engine bay?
So you can use the front fan to propel yourself in the water once it is covered?
;p
I've had my stock (31 tires) 62 in over the headlights 30 to 50 feet at a time crossing rivers and never had a problem.
Only once where I covered the hood did I have problems, and it wasn't until the next day.
Dry out the distributer and on your way.

Siliconed the cap shut, siliconed the plug caps to the v/c (FZE) Dielectric grease in the wire ends. Dielectric grease in the electrical connections.
after the dust I encountered in utah this past weekend. I'm getting a pre-cleaner for the snorkel on the BJ. Clean air and fuel are crutial to diesel longevity.
FWIW I swamped my 40 with spring over and 35's. Sometimes the dizzy and other stuff is the least of my worries and now so is the air intake

Benji said:Wow, I guess you need a snorkel.
Didn't need no stinkin' schnorkal here either!
But there was that one crossing where water was comin' in the drivers window. Now there I needed a schnorkal !!!!!!!!!!!!!!!!!..................... And a strap from Jack and the atomic snow pee. had to ride for four more days on garbage bag seat covers. Even a 383 don't get ya through the deep sometimes.
Later,

Hi Sean,
Ya but it sure raises hell on the U joints and CV's.
Some like Mud, some like rocks, Me thinks deep water is my thing.
And no! I dont need no stinkin' schnorkal.

So let me get this straight......
Your factory intake, BEHIND THE HEADLIGHT, gives you a "much higher ram effect" than a snorkle? I'm no Physics genius, but I'm smart enough to know that air, like water, is ALWAYS going to follow the path of least resistance. While it's true that the factory air intake has a much STRAIGHTER shot to the engine, 1st the air has to GET to the intake. (The same intake that is BEHIND the headlight!!!) This is the WHOLE IDEA behind an aftermarket ram air system. It RAMS air into the airbox! Try ramming anything into your factory intake....What's that, you can't even see it from outside your grill? Now pretend your air!!!
2nd, as has been stated, the intake is behind the headlight. What does a headlight produce besides light? HEAT!!! Not only that, but heat rises in an engine bay. The intake is near the top. You do the math.
;p
While I agree that the factory intake is behind the headlight, it is not completely obstructed by it.
Also, and I did the following experiment myself, at any speed above 25 mph the ambiant air temperature outside the hood is equal to ambiant air temp under the hood. There is so much air flowing into the engine bay (through the grille, under the engine, etc...) that temperature difference is non-existant It's only at slow speeds and at a stop that cooler air is warmed enough to make a difference.
(above experiment was performed on an Acura Integra which is closer to the ground and has a much smaller grille than our cruisers)
So perhaps the better option would be to move the factory intake to the center of the vehicle by 1-2 inches thus puting it directly behind the larger openings?
I have not performed the flow measurements but I have a hard time believing that air that has to make 3 bends before it even gets to the filter (as in a snorkle) would be at a higher velocity than air that has a direct shot at the filter (factory system). I do not have a flow meter and would not be able to calculate the difference.
I stand by my assertions. however- would welcome any evidence to prove me wrong.
The only advantage I see of having a snorkle is to get in cleaner air (yes a big advantage), provide some level of water proof'ness' to the engine (which I have no need of), and perhaps the biggest factor- the 'coolness factor".

Can you say, "Hijacked!!" ??? LOL
I think you have a fantastic idea in moving the factory intake to a more conducive environment for airflow. I have debated doing that very thing several times! Also a good comment about the temp in the engine bay. I have NOT done such an experiment, so I'll just take your word for it! As to the 3 bends in the snorkle intake, my ram air system on the Gt had to make 3 sharp 90* turns before it ever made it to the aluminum intake. The company which sold the product claimed HP increases up to 20HP at highway speeds over the stock 215 HP 4.6L. Now, while I didn't have a dyno to confirm these claims I just had to take their word for it. I would estimate the gains to be more around 15HP above 65 MPH. Regardless, we are dealing with 125-155 HP dogs, so even if the snorkle does work as a ram air, the HP gain %wise would only give us about 7-10 more HP. I'm with you, though. The idea about moving the intake is a great one. The problem would be with getting road spray taken into your air filter causing it's life to be greatly shortened. Good discussion, Doc!
You summed it up Doc. I completely agree with all of your terms.
I think it would be interesting to move the stock air intake in front of the grill for more 'ram air." Though, I hesitate as the engineers at Toyota placed it in the stock location for a reason?
The snorkel I would agree does not provide more 'ram air.' For the cool factor, they worth the money, but not the holes in the body.
Don't get me wrong, I wish I had one.

I believe the reasoning was to lessen the intake of road dirt and grime, as pointed out above.
I WOULD NOT move the intake over if you had a K&N installed, with a proper paper filter you'd have less chance of ingesting gunk. Still, perhaps a 'pre-filter' would be in order?
Benji said:
Me too. For all the bashing I do on the effectiveness of a snorkle, I think they look completely bad-ass installed, and would get one in a second if I didn't have to spend that $250 on tires.
Doc said:
Doc,
I've been doing a lot of thinking about this one. I finally got the chance to look under the hood and it didn't look like I was originally thinking it did. The intake is actually tucked into the driver's side fender. I looked hard on this site and on ebay to find some pics, but to no avail. I don't have a dig. camera-the wife decided she wanted a nice print photo camera
Anyway, I was just thinking of how hard it is for the engine to pull air out of a fender that is (for the most part) sealed up. Granted, it's not completely sealed, but there really isn't any significant airflow into or out of the fender. Correct me if I'm wrong, but it would seem that the engine would actually have to pull the air into the filter box. Then I started thinking about the airflow that might be entering in by way of a snorkle. If I stick my hand out of the window doing 60mph, it's a pretty powerful wind pressure that forces against my hand, trying to move it backward. I figure the size of my hand flat against the wind is about the same size as the intake of a snorkle, maybe smaller. Wouldn't this same wind pressure help force air into the snorkle tube and into the airbox? The angles would slow the air down some, but the pressure never lets up, it continues to push the air in as long as the engine is accepting the air (creating a pull?) and the vehicle maintains a highway speed. I think it would be similar to the ducting system in a house. The ducts have many bends and turns, but the air still moves through the ducts as long as the fan is on. Couple the wind pressure with the engine pulling(?) air in....am I wrong here? I just can't understand why you don't think the wind speed is sufficient to push the air into the airbox after considering the hand-out-the-window example. Surely it must produce more air for the engine than the factory system? It sure would be nice to have an air flow meter! (Or an automotive engineer!)I also checked how hard it would be to move the intake from inside the fenderwell to behind the grill. It would not be real easy, but it could be done. What little space there is between the radiator and the headlight assembly is covered by the headlight and grille frame(?). This steel frame would have to have a hole cut into it the shape of the intake. Not a difficult job, but I don't like the idea of cutting the headlight/grille frame. No different than cutting the fender for a snorkle though, right? At any rate, I do think that this is the best idea, as long as you don't go through water over the headlights (which I don't ever plan on doing!).

Like when wheeling for example?

Um, that would be a yes. :whoops: at the speeds you see during crawling a snorkle could have a nice advantage. That was originally not the comparison, but is a very good example of where an inboard mounted intake would loose out.
Wildabeast60, I'll take some photo's tonight if I get a chance. I was pretty sure my OE intake opened up right behind the headlight... Maybe I'm thinking of a different vehicle. Anyway, we'll get to the bottom of this.
On the ram air effect a snorkle sees- yes it does get a nice ram air effect at speed, I was just comparing it to the OE system, which I THINK has a greater ram effect because of the straight shot. But, the OE intake tract is rippled, and the snorkle is smooth, perhaps it has the advantage anyway? I'd need a flow meter to be sure- and I don't have one. It would be an interesting comparison- a smooth tube with bends, VS a rippled tube with no bends.

This post went way further than I ever thought. But it's been fun to read. My quick thoughts
Moving the intake to a better position in the grill would be cool but... Last year I took my headlights and grill off to paint them black. After I started I realized I did not have everything I needed so I went to the store with the grill and headlights off. This meant that the intake tube was wide open with no obstructions. I drove 25 miles each way on the highway. Overall I noticed no differance at highway speed in hp, but I did pull my air filter later that day and noticed a huge problem. All of the bugs that normally hit the grill went all the way to the air filter. Some even hit with such force that they burrowed into the filter.
It would be easy to fix (some marines in Iraq report using panty hose on the outside of hummer intakes as a pre filter) But I thought it was intresting.
Last thing does anyone have any pics of a homemade snorkle?

I'm going to ask a physicis guru this weekend, but I don't think the bends in the snorkel are that much a limiting factor to the "ram air" effect. The pressure in there is keeping everything moving and there is constantly more pressure because you are traveling and forcing new air into the snorkel, just as if you had your intake right behind the grille. Yes there is more resistance because the air is forced to to make the curves, but if you take a bendy straw and blow into it and bend it, it doesn't flow less or get harder to blow into... think about turbo charged vehicles with front intercooleres they have crazy angles in their intake paths, and they still get plenty of boost...
Like I said, I'm going to ask somone with a PhD in Physics/Astro Physics and end this

Bwahahahahaha
Bwahahahahaha
Stop pisssing into the wind....its a fawking tractor motor. The snorkle may get more and cooler air in there but you will never notice it. You will notice when you dunk your truck up the wind shield. stop fight you dipshits....
.....there is homemade snorkle pics in the tech section
