jeep TJ/LJ snorkle question

[BIGdaddy]

i want a snorkle on my rig. I'll probably end up with the safari...

that being said, why the heck do you take the snorkle ALL the way down to basically the lowest point of the fender only to route it up and into the factory air box??:sport_box

I mean,why not do something like the AEV JK snorkle where there is a bit cut out of the hood and you connect to the airbox which is RIGHT THERE under the hood.

Will AEV put out a TJ version of their snorkel? I'd buy it.


p.s. i'd just fab my own, but i think smog laws get tricky when you do intake stuff that isn't carb approved. I dunno...

not sure why they go to the bottom of the fender. but one caution for installation. in order to remove the passenger door the snorkel has a small depression in it, so when you lift the door the hinge will come out. make sure the placement of your drilled hole will allow that depression to be high enough to get the door off..

I too wish they went in at the hood, or even through the cowel. To go all the way down under the battery tray seems a little bit much.

Its to get that low "cool" air.

lol...you made me laugh.

Chris from AEV joined us at our booth at the Jeep show in York, PA this year and he brought their black Expedition Package JK......man, that thing is amazing.

:drool: If ever won the lottery....

You would have to ask ARB why they designed their snorkle as they did, but my guess is that their design does not require modification to the hood -- on purpose.

It is expensive and difficult to modify the hood and do it right. The AEV product uses a custom hood along with the snorkel and airbox. I would expect the price to reflect these differences. With the Safari unit, all you need is a circle saw and a paper template to install the unit, and you cut through essentially flat sheet metal. Coming in through the hood requires cutting in three dimensions and finishing the result to eliminate sharp edges. You would also want it to look professional, and not like a hacksaw and poop pipe job. It isn't as easy as it seems.

AEV offers some sort of template, if you don't go with their hood, so apparently its not THAT difficult...i agree that a hole saw, mostly hidden by the body of the snorkel DOES look more professional.

I think getting outside air is an okay goal, but I think snorkle's are in many cases a bit ridiculous. It depends, I suppose, on what you think they do for you, and what you think your driving habits are. Some folks seem to think the snorkleized intake gets you somehow out of the way of dust, and then I guess some folks think you can ford deeper water with one--which I guess is true.

I have to ask myself if I really feel the need to ford water so deep that I need a snorkle, or if I've ever experienced dust so well-stratified that I could have some assurance of a snorkle getting me above it.

No to both, for me. I'm doing an intake using the Safari snorkle ram air accessory fitted just above the bonnet. No snorkle. If water is above the bonnet, I've got a bunch of other problems to worry about above and beyond engine water ingestion. As for dust ingestion, I don't buy the 'get higher' crap. Just because you don't see it in a nice photo doesn't mean it ain't there. It's almost as if folks think there's no more dust above roof level. Why izzat? Why is roof-top the magic height? How about bonnet-top? Izzat high enough? How do you know?

I think it's a load of crap, and I think a highly-protected stock intake might just be a better option for most driving conditions. If you really anticipate fording water over the gunwalls, best wishes.

Yes. And if you believe it's because of 'sound engineering principles based on field experience', then I think you're mad. My sense that ARB produces squat based on anything other than marketing's demands for crap is tossed right out.

hmm...i disagree with both your posts, but i appreciate your opinion.

What I believe is that I didn't say anything about sound engineering based on field experience. I suggested that it was easier to do it the way Safari does it. As for ARB tossing out "crap", I don't think so for the most part. I have been to their parent facility outside Melbourne and talked with several of the folks there. They seemed okay to me as far as quality of product. There are some exceptions, but ARB is generally willing to rectify the mistakes they make in outsourcing.

Okay, sure, but tell us what you really think.

There are plenty of different ideas out there about what snorkels will or won't do, or under what circumstances they might benefit an off road vehicle. What they generally won't do is provide ram air because they are too restrictive in total CFM.

Mounted at or above the roof they will pick up cleaner air than the air available at the grill if following another vehicle on a dirt road. It may not be clean air, but it will be cleaner, depending on how close you follow the leader. You may wish to observe this for yourself, or you may wish to ignore it. That's your privilege. Dust settles from the top down, so you will get cleaner air faster with a lifted intake. The Brits have been using this principle off road since the invention of rubber, and they have it right.

Fording deeper water is also a question of perception and definition of terms. Deeper than what? You don't need to ford water over the hood to make use of a snorkel. I have drowned engines by splashing through 6 inch puddles. I have never drowned an engine with a snorkel attached, even in water up to 5 feet. The real benefit of a snorkel with regard to water crossing is protecting the intake from ingestion of any water whatever, and protecting the air filter from getting wet and closing down. Your tires will lift water from the trail into the engine bay, and your fan will distribute that water all around the bay at tremendous velocity. Splash water will bounce up, around, and all over under the hood due to tire splash and fan splash. None of that really has anything to do with deep water. You may see a snorkel as stupid. Lots of others don't.

Yes. Agreed, and point conceded.

Yes. If I said 'stupid' then my most humble and sincere apologies for being an arrogant, and ignornant, ***. A typical, and unfortunate, combination.

For now, I'll just say that I feel what's on the end of the intake may be more important than intake location, certainly when it comes to dust.
