Snorkel Mod
« on: June 17, 2011, 03:31:45 AM »
I was all set on ordering that eBay snorkel until I saw monmendoza\'s stainless one which is a beautiful piece of work. I\'m going to follow the same design but use exhaust tubing and get it powder coated black. I doubt I\'ll have time to actually fab it until the middle of July but I\'ll start gathering the parts. I\'ll probably be using a Pelican Box I have for the air filter if I can find a filter that\'ll fit it.

Monmendoza\'s snorkel!

Hey Monmendoza, what size tubing is that? 2.5\"?

i\'ve seen these Unifilters on a few rigs, and as I am also looking into fabricating a snorkel was thinking of trialing one. it\'s basically a foam air filter at the intake, so air is filtered at the top of the snorkel. any thoughts or pros/cons?

as it\'s pretty dusty in the summer when i\'m havin a bush bash, I was thinking of running one of these at the top of the snorkel and then also having a pod filter enclosed in a water tight air box inside the engine bay. So a dual filter set up. No idea how well it would run though, maybe not so well at low speed due to flow resistance from two filters, but yeah, any thoughts? Definitely a fan of monmendoza\'s design!

hello Ogre(palmer) IIRC it is 3\". It is the same size as the snorkel head.

what process do you use to cut the hole in the fender

there is a drill attachment that drills a much bigger hole. Unfortunately what I had was 2.5\" so
I still have to manually enlarge the hole with a large file. My friend had his done by a professional
shop and he drilled a perfect hole slightly larger tha 3\". Then he cut 1/4\" plastic tubing along the
lenght and tubing. he then installed this in the fender. His installation look much much better than
mine. I will get a picture when I see him and post it here. :)

ahh no worries, i thought it may be a hole saw.

I would get a shop to do it myself just to make sure its done properly.

I think i will make it from PVC pipe and just paint it matt black.

Ill keep the filter in my engine bay, im not going to go underwater just stop splashing etc so a bucket with the filter inside and pvc glued to it will be fine.

They call those pre-filters here and they are supposed to block the larger stuff from entering the system. The snorkel head shown in the picture is not the pre-filter type of head. The head shown will vent out a lot of rain and dirt because it has some vents that force that out of the system as it hits and slides down the back side of the head

Here\'s a pre-filter that\'s for very dirty environments (there is also the inline type). From what I\'ve read they are fairly restrictive so they aren\'t recommended for a daily driver but they do a good job in those harsher environments:

If you drive around on dirt roads a lot then you will suck quite a bit of dirt in through the top of the snorkel. It will occur when your behind or drivng past other vehicles. It is actually a signifficant pitfall of using a snorkel. Also you have to stop splashing around so much during rainy times. They are amazingly effective at keeping out rain.

Just after I put the snorkel on i went for a long drive during a torrential rainstorm and when i got back i checked, not a drop had gotten in.

one of those snorkel beanies will prevent dust getting in and it will keep bugs out, if your trying to cover some distance during one of those cricket / grasshopper storms like what we had during the summertime. I prob should get one actually. You can also just spin the snorkel head around 180, that would probably help keep crap out. IDK if I would run a beanie on the streets though

The Applause filter setup that i did works pretty well and was about as easy as it gets to do. you can get a K\'N to fit that box also off ebay, but i am really dubious about the real benefits of those kinds of filters. They look cool and make your motor noisier, but otherwise i think they are pretty useless. If the air can get to the filter fast enough, the motor will suck it through. The real benefit of a snorkel is getting cold air into the intake because cold air is way more oxygen rich. If you use them outside of a box in dusty environments you will suck it more dirt, no doubt and the air will be hot because it draws from above the exhaust manifold, which is the hottest possible place. I seriously dont believe the crap on their website about them stopping more dirt. Probably the best thing about them is that you can clean and reuse them.

Everything I\'ve ever read about the K&N\'s say they allow more fine particles to pass through which will reduce engine life for sure. There is no real study to provide such proof just a lot of people with real world experience.

As far as dust the snorkel should actually reduce dust intake from traffic on dirt roads since it sits higher than the grill area where the cold air intake is. In other situations like a dust storm the snorkel will probably suck in more dirt.

the beanie idea sounds good to me just have it in your ride & if you see dust storm conditions put it on just remember to check it often so it doesnt clog.  IMO the design has been well thought out for the head so I dont worry much about debris coming in plus thats why we have the filter in line, just keep it clean & if it doesnt preform well its probably dirty.  Our rigs come stock with a restricted system so I belive a snorkel along with a simpler air path way will be an improvement.  my main interest in a pod filter was the ability to clean it & reuse, my main interest in a snorkel isnt to drive my Rocky under water just to get through that 4\' deep stream now & then my main worry there is floating away HAHAHA with flexible tubing under the hood maybe we could unhook the snorkel if we didnt like the way it preforms for daily driving??  Side note: Ive seen some jeeps around here that run a tube through the firewall into the cab if someone didnt want to alter the looks of their Vehicle that could get you through the deep stuff, just have a way to un hook it like I said for Daily Driving.

my main worry there is floating away HAHAHA.


Mate, just take the rubber bungs out from the floor pan. That way you\'ll fill up but at least you won\'t float away :silly:

From the research I\'ve been doing pods aren\'t really a good option. As alaskan pointed out, they don\'t filter well and, after talking with a mechanic who specializes in engine mods, apparently if you don\'t get a high quality high flow one they can restrict air flow quite heavily. He suggested driving up a hill while checking your revs in any given gear to see how good your acceleration is. Then take the pod off and trying it again. I have a pod and plan to give this a go (just as soon as I get off my lazy ass).
Also, you really don\'t want to go through water with a pod. The original box has a bit designed into the original pipe\'s low point designed to capture moisture, a bit like a U bend under a sink (kinda). There is also a tiny hole (or 2?) in the bottom of it so that moisture can get out. If you\'re making a custom intake it might be a good idea to plan such a low point to gather moisture as apposed to having your manifold as the low point. Hope that makes sense.

Your right I\'m sure, I was hesitant to remove the moisture collector but I did save it.  When I fit the snorkel it\'ll possibly be going back in but I dont want the holes to become a way for water to leach in.  I like the idea of the test I\'ll be trying it when I\'m back on the road.  I made a case for the pod filter which is air/water tight & the filter flows very well.  All good things to think about.  There is a way to modify the original air box to fit a Pod filter which is very similar to our original filter, I\'ve saved the original too but I would want to remove a lot of the bends.

Volant

I like the Volant one the best but cannot find just the head itself. I also like the proven ARB with this stainless grill:
