Snorkelling along

[Mick-Kelly]

Call me wierd if you will

hoot man tobesuretobesuretobesure
(back in the cupboard Patio)

but the disco i am hopefully goingto be bringing home over the weekend is fitted with a snorkel. looking out the window at our current inclement weather got me thinking about the ram air effect and water ingress into the top during heavy rain. I know the head is able to be turned around but what do you do when its pi##ing down and you dont have a screwdrive/want to get wet.
Any experience of this out there
cheers

Mick,

The Safari boasts a drainage system that is supposed to allow the worst out before it finds its way to the box.

I have checked mine after driving in rain and there can be a little water on the bottom of the receiver but nothing to worry about. It would have to fill up about 100mm in depth before it gets to the filter and then find its way through the filter and to the engine. Not likely.

There is much more risk without one.

In summary: relax not an issue. :?

Groovy, thanks for clearing that up. I assumed it would be something relatively easy

I have the Airtec brand and run it facing rearwards, I found doing this helps me alot when it comes to the dry season. The only down side (if you can call it that :roll: )I find, to getting cool, clean, water free air,,, is that while all the dust and water is avoided 8) ...... the big arse bugs up here on the Cape seem to be fascinated with my snorkel intake 8O ,, Its quite amazing how many dead bugs you can collect in your air box. There is a slight increase with intake noise wit it facing rearwards, but only on the rare occasion that I have windows down and well worth not injesting all those bugs. I would tend to argue that in real terms we only achieve negligable ram air effect with the head facing forwards. The turbo is forced induction anyway.. perhaps differant on a V8, but even there, though technically ram air is helping, the added friction and obstructions of the snorkel itself will negate a lot of the Ram air and then we dont exactly have racing air pods on our discos so the ram air is becoming more of a slight high pressure present on the dirty side of the cleaner.
But if you really want to achieve the Ram air that is availiable, you can rest assured that even in the heaviest of down pours you will not flood your airbox, infact you will be surprised if you run your engine and get your hose,,, spray as much water as you like at your intake,,,,Most of it will just run out of the four slots at the base of the head. It relies on the water being heavier than air and squashing out on the back walls(basicsally) just make sure you mimic the road speed by spraying it at your intake :wink: dont just pour the water in as if you are filling a bucket.... 8O But even then you will probably be amased at how much water the standard air box can injest, sqaush out, and then drain thru the one way valve at the bottom......I'll shut up now,, but if you look close at the intake on Td5 I have there is some pretty gouchie air speed manipulation/swirl induction/water seperating plate/ and then the depresurisation of the air as it enters the airbox true that encourages the heavier water to fall more readily than the lighter air,,,,,hence the element is such a relatively large flat surface above the air intake.. not just to filter dirt style_emoticons/<#EMO_DIR#>/smile.gif Its a beautifull thing really 8O ........yes I know my wife thinks its sad too :oops:

Hi all
The drain holes in the bottem of the air box are sealed up, that came with my snokel.
Dose this sound right.

I have a safari snorkle and it lets in only a very small amount of water, and this was from driving in the damm cylone last week.

Please refer to the photo below to see how the water is dispersted.

hook,
most offroad places block drains in airbox soas you dont suck water when wading!!!.Mine are NOT blocked for the simple fact if I wade that deep puter is stuffed.So if you dont want to float down the river just unblock drains and any water that may find its way into the air/filter box will run out. Too easy

[Mick-Kelly]

Hmmm i'll remember that about the airbox plug. I will be using the snorkel for dust rather than water. Does anyone have good or bad experience with Donanldson pre cleaners
cheers

Hook,
blocking the drain plugs is not ideal, unless you do it with one way valves/rose buds/weight flaps what ever you want to call them. However If you just remove them to create an open hole, you start to defeat the advantage of dust free air from your snorkel you will find dust a bigger problem entering open drain plugs than water.
The water will flow in, but it tends to offer more resistance being sucked thru the wee drain holes than the light air coming thru the huge hole that is the intake. or this is what i have experienced over the years.

Perhaps you can just take the two rose buds you rip out from your aircon drains and mount them in the bottem of your airbox.

I have a donaldson air ram and it has the drain holes on the back and they seem to work ok.

To keep the bugs and other crap out I use a finer filter air ram cover. Its just a foam filter sock that you oil and fit over your air ram. On road this is the filter I use as even when the outside is filthy the inside is always clean. They only cost about $20 so I have two so I can fit one while cleaning the other.

I've used a donaldson pre-cleaner (I'm assuming you mean the cyclopac type) for a trip across the simpson (and to and from). It certainly collected some dust in it and plenty of insects.

The 7-1/2 inch cleaner will not fit on the top of a Safari snorkle without making/getting some form of adaptor (something that ARB didn't bother to tell me when they sold both to me).

I have also heard that they loose their efficiency above around 70kph but couldnt really comment one way or the other.

The 4x4 shops use silastic to block drains, just remove drain CLEAN and replace.if all **** is cleaned it will not draw water /dust ,but weight of water will allow same to slowly clear.
one thing for sure water and diesel donks dont mix.
have fun.
