Outer Limits 4x4 Board

Gday guys, so im really close to fitting my stainless 3 inch snork to my truck, ive got a 2.8 d 93 lux, the old safari copped a floggin when i rolled the old one, so thats outa the question. I see pootrols and luxies and everything with them, with just a 45deg bend at the end of the snork, top of pillar. Does this mean there donks are drinking water when it rains as well as fuel? This worries me as i just got the truck, dont want to fill it with water... Can anyone explain how they dont suck water during rain? Thanks guys appreciate it

Hey, a little bit of water along with your air intake improves performance.

Personally I think most snorkels, even the expensive ones, would suck a little rainwater in, most of it would settle in the pipe at a low point and evaporate away later, the rest would not be enough to cause any problems.

It's more a big drink through submersion that you have to worry about.

That's just my opinion though, I'll probably get shouted down.

I'm not shouting chimpboy... just talking normally

The old donaldson syle ram heads that were (are?) fitted to safari snorkels are designed to make rainwater hit the back of the ram and be channeled out of the little vertical slot at the back. A very clever little piece of design.

Can't comment on the newer, more streamlined ram heads on most snorkels today.

Most of the rubber elbow/stainless pipe style I see are left pointing rearwards.

I am not aware of rainwater being a problem in any case.

Oh ok, well i was planning on having that elbow rubber pointing backwards, not to follow the trend, just because ppl are doin it for a reason. My safari has that same descrition your telling me about, dad pointed it out how it goes along to the back off the head then there is four channels for it to secape. Well i aint keen on submersion, hiluxs are good but its no good for any rig Ive seen a few done with the blue intercooler cheap crap for ricers? I aint doin that. Looks like shite. I went to diesel spares and got quoted 70 bucks for all the joints and dad got the clamps from work, and looking like 75$ ish for 1.5 m of 3 inch stainless. Sound alright price wise guys?

the reason why alot of guys werent running a head on the top of the snorkle was they were getting better performance.

when tuning how much better i'm not sure however i have been told this and it was posted somewhere on here a long time ago..

the fact that some heads are turned backwards, and that alot of the stainless ones, dont use heads at all, they just leave the pipe facing back, as has been said already. does this effect performance at all? like do they preform better with it raming in a little, (i know it was mentioned that people wer leving them off for performance) but i always thought that the motor would struglle to pull air in through it facing backwards, ( i also thought that reguarding the old scoupes on v8s that faced backwards)

Bonnet scoops face backwards so that air coming in through the radiator has somewhere to go, hence better cooling. The engine's air-drawing capability is such that the air intake is not going to be affected much by what is basically just a bit of wind.

the blue "cheap crap" is actually not cheap crap. it is silicon hose rather than rubber. the reason people use it is because unlike black rubber hose, it will not perish when in contact with oil or fuel. and it also isnt cheap, on average its worth around $15 per inch!
Mack trucks actually use it as their radiator pipes.

seeing as you are using it on an air intake, it wouldnt be necessary to use silicon hose as there will be no oil/fuel passing through it.

the only negative to facing the intake head backwards is that you wont get the ram effect when on the highway, besides the wank factor, this is why alot of people get snorkles these days - for better fuel economy.

Oh righto, i presumed tthat stuff was 'cheap crap' because they sell it at 'super cheap' lol. so basically, from what ive gathered, from whats been said, that facing it backwards aint too bad, except for the fact that ovbiously the ram affect as you no it dosent happen. So my highway trips might not be good, but it surely has to be better than no snork at all?? And yeh with the no fuel and oil sct touching it, was the reason behind not usin it. So as for the cost guys, any good? Thanks to all who helped.

also have heard facing backwards stops icing up of carbs etc

Dont you have em facing backwards to stop a lot of dust being forced down the snorkel?

I don't believe the dust is a major factor. The dust flowing around the rear facing pipe will get pulled into the low pressure area behind the open end of the pipe and get sucked in anyway. It will help though with not sucking in leaves, pedestrians etc as the cars push through overgrown tracks - I find this a problem (I have blocked my head up with wet leaves on occaision)

I believe the rear facing pipes are also associated with avoiding spray from hitting water fast getting blasted into the snorkel head - it is a comp car thing.

Also though, the more powerful comp cars run 4" tubing (I imagine to free up some HP - about 50% more flow from 3" to 4") and have you seen the size of a 4" ram head

Steve.

Hey g wagen. Yeh well i might just have t go with the four inch on the lux, just run the dyno and the big block 2.8 that im running wouldnt even read on the computer, too much power!! lol

im thinking 3 inch would be more than substantial

hey guys, just did a snorkel for my lux this arvo cost me 38 bucks ended up goin with piping that was just a little bigger than the air box inlet was, i think 65mm. still deciding what to do for the head, atm i got a 90deg pvc pipe end lol put it facing backwards... seemed like the best way to face it given the facts.

One thing however is .... i hear its supposed to stall the engine if u cover the end ?
well mine dont stall theres a minor drop in engine sound but other than that it keeps goin, havent tried upping the revs in that test yet tho.
i thought i did a good job at sealing it :(

Be carefull when doing that as it will suck your aircleaner pipe flat and you might bugger it with a split or something.

The reason it should stall is that it should be the only path for air to get to your motor. So, if it's not stalling, you have air getting in elsewhere, which means that in theory water could also get in elsewhere.

Without commenting on whether the "hand over the end" test is a great idea, I suggest you get a roll of duct tape and apply it to all the joins in your snorkel system. It isn't pretty but it seals the joints and unlike silicon etc, you will actually be able to see when it has deteriorated and stopped sealing.

Good idea chimpboy i have a feeling its the seal on the airbox cap that covers the filter, its probably the original seal. And i was watching for the tube sucking flat but no where near that airtight.

what are people doing for ends if they arnt buying safari ones ? i mean regardless of facing it backwards or not are people putting a filter or mesh cover on them ?

home made i dont know what you could put over the end filter wise, could use some kinda sponge stuff, but with all the cars facing it backwards without the ram off the saffaris, there should be an aftermarket head.

i thought another main reason for facing it back was fallowing another truck through the mud, a big as lump of mud inside the pipe wouldnt be to nice?

Better fuel economy by bolting 2m of convoluted piping to your intake?


A much cheaper alternative to silicon joiners is fuel hose. Readily available in sizes 2-3 inch, cheap and made to handle fuel and oil.
Of course the fuel hose only comes in straight bits.

better fuel econ ? only way i can even think that would happen is air being passed into the engine rather than being pulled in, and more cleaner cooler air in means it combusts better ? i admit i aint a mech so that might be bs id like to know the real reason tho

A cold air intake will help a diesel (if it hasn't already got one). But there are ways to get cold air into a diesel that don't involve an extra 2m of pipe.

Ram air is insignificant for a 4wd and the speeds it can reach, if you're approaching 300km/h then it's worth considering.

oh lol well there u go

mines flat out doin 130 on 31's lol hahaaha. I definetly dont need no ram affect to be happening or you chief88 LOL. Im gonna spray paint this fly screen that i got black, and cut it to suit the end, because im ending mine with the 45o bend, so its directly backwars, dunno how on securing, prolly another stainless clamp. Just to stop leaves and crap. got any pics chieff 88? Cheers

pics i shoulda got today but lights bad atm bit overcast tomoz morning ill have some
haha re u saying we dont have power ?

M8, we got power. Its obvious we do. 2.8 and to my knowledge, yours 2.4. Thats sheer grunt at its finest as i said above big block 2.8

The toyota filter housing has a drain in the bottom of it to drop the water out there.

Silly bunnings only had 90deg angles when i went.

Did you use pvc pipe for the main shaft like me ?

My plan was to get a 45 deg pvc angle and cut half the raised bit off one of the angle ends (you know the bit that goes over the adjoining pipe) then get fly screen like u said and make a cap over this little off-cut piece i now have and then heat the little off cut ever so slightly and squeeze it in the end of my angle piece making a little ring that has enough room for it and the thickness of fly screen all around.... would be quite a fiddly process tho and if it was over-shrunk it would ruin it.

Failing that might have to go with the mesh and ringclamp

i put twin snorkels on mine. got some aluminium flyscreen glued into the back of the rear facing 45 degree bend. very happy with the outcome, no performance difference on a tb42....but it does sound very nice hearing the roar of the air getting sucked in. a mate put a ram head on his td pajero and noticed a marginal power increase (non intercooled).

i only paid $20p/m for my stainless pipe. 45 bend $21, 90 bend $17

damn that looks heaps good
