snorkel water/rain intake question
snorkel water/rain intake question
Hi all,
Ive finished installing my snork a couple of weeks ago, but havent plumed it up on the inside os my MK yet. Since the addition of the 2 inch body lift, the 2nd-dary air filter (the one bolted to the side of the firewall has been binned. So i only have the primary (ie on top of the donk).
So my snorkel comes into the car on the side and was just a little worried if i plum up the snorkel to the primary airfilter, how is it going to go with rain? is the rain gonna end up in the engine?
Its an Airtec snorkel with a Safari snorkel top(head) on it. Ive checked the bottom of the snorkel and there are NO drainage holes.
So, will the snorkel take in rain? and what happenes to the water? as i dont want it in the engine.
cheers and thanks.

the amount of water you are going to get from driving in the rain will accually be good for your motor as it will steam clean it you think about it you are not going to suck in 3ltrs in one gulp just small amounts and while your motor is hot and running it boils the water and you only have water vapor then with more oxygen entering your motor
I DONT RECOMENDING POURING WATER INTO YOUR INTAKE BUT THAT LITTLE AMOUNT FROM RAIN WONT HURT...

until you put it in a bog hole and water from the tyres flows straight down the snorkel.
there was a youtube video, think it was team RPM driving, said he had a ridiculous amount of mud and water down the snorkel.
question with one way drain, surely it takes a certain amount of pressure for the water to go through it? and isnt it going to get sucked shut by the negative pressure generated in the snorkel, and any positive pressure benefit you get from the snorkel will be nullified by the valve letting it out.
is there something im missing? want to build my own snorkel after pulling my airtec due its ridiculous attempts at keeping water out...
cheers, andy

The rams are designed in such a way that any incoming rain will hit the back of the ram (force fed) and drain naturally out the back through drain slots.
Reversing the ram intake isn't recommended by the manufacturers because moisture is being 'sucked' by the induction of the motor and therefore there may not be enough force to make that moisture hit the back of the ram and then drain out...it could drain straight down into the donk, probably not enough to do any harm.
I've never had water or moisture probs yet and my ram always faces forward unless i'm ploughing through heavy gorse or scrub.

Ohkay, iam kinda buying the 'steam cleaning' the engine thing, but seriously, so some of you dont recommend a one way valve? and yeah, whoever said that about the negitive pressure sounds logical too....
Intresting....
How hot will the sd33t run? hot enough to turn that water into vapour?
cheers.
so no low point drain valve then?

two diffs, what if you dont have one of their snorkel heads?
and isnt it something like a teaspoon of water will hydro-lock a td42? ill leave steam cleaning to my carpets, im quite happy with all the soot inside my head
and wet filters and water hitting my turbine are not what i want either.
must be a better solution than using a head smaller than the pipe size i want to use, maybe truck ones have a 4" hole?
still dont trust them to work the way they say they will....

He said he's got a Safari snorkel head so it should have drain slots in the back....mine has. (Mine is same - Safari ram head on Airtech snorkel).

Have never tested it but my understanding is that it's a tablespoon of water thats enough to rip your td42's undies.

i have a custom snorkle with a safari head on my rig. forwards or backwards if i am driving in the rain a lot i was getting enuf water to stop or make my engine run like poo. i have added a gq 1 way drain and its all good now. i have pulled my air cleaner top off to find at least half a glass of water every time.
how bent are the rods?
which GQ 1 way valve are you talking about? the one in the cylindrical pre cleaner, which is more or less a gaping hole in the bottom of a cyclonic cleaner, or is there something i dont know about?

From what I have found, the safari is very efficient at dragging whatever moisture is presented to it, straight down onto the filter media, which is laden with dust, and turns it into a layer of wet mud. The greatest concentration of mud is where the air enters the air filter box.
I installed a brand new filter before a weekend, drove thru some pretty dusty tracks on day 1, then hit fog and light mist. By the end of the day, the car was running like a dead slug, didn't find out until a week later when I had a chance to investigate.
So for me, the theory about water running down the back, due to the ram head profile and the water vapour enhancing the performance in some way by cooling the air stream or something else is a hard one to swallow. Water and dust equals Mud, which air doesn't flow thru. The ram head does not seperate the moisture from the airstream, just jams it down the pipe. I agree you will get less splash water if the head is backwards, but even if normally mounted backwards, if moisture is in the air, and that air is sucked into the inlet, the water stays entrained and hits the filter.
I have now taken the ram head off and am having a shot with a donaldson head. I don't expect a great return under the conditions above, in fact it feels a little choked to be honest, but at the very least I wont have a hundred flies and beetles and bugs stuck in the mud as well! I am also going to give a finer filter ram head sock a go, and also one of the long socks that drape down inside the snorkle body, and see if things improve to a point where I can say one is better than the other. I will try each seperately of course - will let you know.
