2 questions about my Safari snorkel

[gilbo Junior Member Find all posts View Profile Close gilbo]

Hi guys

I read in the forum somewhere that you should always test your snorkel by blocking the intake with a plastic bag or something else that will do the trick.

anyway i tried this and the engine didn't stall, so i used 3 bags on top of each other and it still didn't stall - does this mean 4 sure that its not working properly?

also, the snorkel head does stick out a bit, would it make any difference to car performance if i swivelled it round and had the intake pointing backwards??

thanks in advance for your help!

Hi Gibo,
Snorkels are not supposed to be air tight cos when the rain enters into the head, there is provision for water to drain.
ARB tell you that in some circumstances like thick dust and heavy rain, you should turn the head to the rear.
Hope that helps.
cheers

thks Les

so the fact it didn't stall doesn't mean its not been installed correctly?

i'd like to turn the head around for all driving too, just not sure if it impacts anything, i suppose i could just do it and see how it goes..


cheers

To my way of thinking, if you took off the head, then choked it, you would think it would stall..... Just a guess mate.

Actually, I don't think it should be possible to stall, due to the drain holes in the air cleaner hosuing.

I am not sure why you would want to turn the head - unless you may be in a heavy snowfall - even then, I think I'd rather use a snorkel sock.

If you're in really thick, choking dust, you might want to consider a precleaner such as a Unifilter or a Donaldson.

Hey Gilbo,

No worries, mate. I guess that's the reason why some prefer the lines of the Airtec snorkel.

I'm actually the opposite, I like seeing it there - nuts eh??!

What impressed me more about the Safari was the sheer amount of information I was able to find on it, whereas the Airtec seems to have very little information around.

Funny thing with TJM - it was the same when I tried to enquire about their steel bullbar. All I could see was the one picture on the brochure - could never see a car in the flesh with one, or could I get some other photos, even when I rang TJM HQ asking for more info/pics.

At this point, I am glad I went with ARB (no I'm not employed by or affiliated in any way with them).

Same situation for me Grandeman - difficult to find much about the TJM products. I'm sure they are quite good but it is nice to be sure.

Mate, its a simple exercise

The snorkel has 3 holes, one on top to take air in
One on the end to move the air to the filter and one on the bottom to drain out any water, that one is a one way type arrangement

If you cant stall it by holding a bag tightly over the head, then your snorkel is leaking air. If it can leak air it can (will) leak water
A big pot of silicone is your best friend...or take it back to your friendly installer...please dont risk that Im wrong

I tried turning mine around as a fuel economy experiment, but the noise drove me nuts, I turned it back the next day. You will get used to seeing it soon enough...

[gilbo Junior Member Find all posts View Profile Close gilbo]

it seems there are clearly opposite views on whether covering the snorkel wil make it stall or not. my mate tried it today and his didn't stall either!

I'm getting the same installer to fit a bar and other bits this week so I'll ask him how I can know for sure that it's fitted correctly.

anybody else tried this experiment?

[Blokeman Member Find all posts View Profile Close Blokeman]

I tried it with my diesel, it didn't stall, but ran rough-as. The air box looked like it was about to implode, so I ceased the experiment! The little dust valve at the bottom of the airbox reminded me of a bad night on the chilli.

Do people think that turning the shorkle head around lets less dust enter
as there would be a low pessure area behind the head. Bit like the back of your car or if you have ute with canopy back flap open. Just a question maybe someone from safari has tested this in Mark Webbers F1 wind tunnel. Cheers Phil.

Hi Phil.

I don't think that it would help in dust.
Big dust (like rocks) would not be able to do the 180 degree turn but I would think that small powdery dust would still get to your filter.

I have only seen it turned around just before a big river or water hole crossing. Have you seen how in a deep water crossing you can get a wave coming over the bonnet.
It flows up the windscreen and could possibly enter the snorkel head on mass. That's where I think the airtech (i think its the airtech) and the standard Nissan ones are a little wrong.
They hug the top of the windscreen with no chance of the said wave avoiding the intake. But they hint at the offer of a little ram air assist by being in a high pressure zone.

It was said before about a pre filter.
You can get a snorkel "sock". You remove the head. Put this sock like filter down the hole, and put the head back on.
I don't have one but have seen them used and they look like a smart addition.

Jeff.

I have also tried the choking test with the motor not stopping.
When I checked in the airbox that little one way valve thingy was inside out. sucked in by the vacuum pressure.
I have not sealed it up and I don't know if I would.
It would all depend on how deep the water is that you will be taking your car through.

My thoughts on this are that even if in water it would take some time to fill the airbox with enough water to get up through the filter and into the engine.
I know the motor sucks but I think that the air would be the easier of the two fluids to suck. As in yes there would be some water coming in through the two drain holes and to a small amount the one way valve but being the path of least resistance "air" would still be the easiest to suck.
Water if entering the filter would still be bound by gravity and would need to build up in hieght from the bottom of the airbox, then through the filter.

On the other hand, if the air box was totally submerged then yes the water would get to the engine eventually.
And apparently it only takes about 1 teaspoon of water in the chamber to do damage.

I have done a few water crossings and general mucking about in puddles and have checked the water ingress in the airbox.
There have never been more than a few drops of water in the intake side of the filters airbox. Just from the splashing that happens under the bonnet.
But I have never been in deep enough to have the airbox totally submerged. I would expect more than a few drops then. In that instance I would most probably seal all those water entry points.

That what I think anyway. Dont take it as gospel and hunt me down if it all ends in tears.
