Thread: Snorkle in the rain query

I have a normal snorkel with the head facing rearwards, I also run a TD5 Inside mild tune. In Hobart recently during a huge down poor of fat rain, the engine sucked in water to the airbox, wet the filter and the MAF went out of range so the engine began to surge due to the MAf signal.

I realised what had happened and in the rain swapped the air filter, soaked up the water and dried the MAF.

I've also fully sealed my air box as my engine was rebuilt due to sucking in dust and I also do lots of river crossings.

Anyway not sure about the Mantec snorkel but mine sucked the water in from the air. So to say it can't happen is false, I wouldn't have believed it either if it didn't happen to me.

Thanks Jazzman - No I wouldn't claim what you have personally experienced couldn't happen - it did! and I can readily imagine having the same experience. What I did do was mock a poster's repeated (unsubstansiated) statements that MANTEC snorkels can suck water out of guttering..... he just wouldn't accommodate an actual user experience.

anyways - happy days - onebob

The above picture is lovely in la la land but, the velocity of the air getting sucked into the snorkel means that all the little water droplets(referred to as 'water mist' in the picture) hitting the walls of the inlet and getting drained off via the drain holes 100% is an impossibility. It doesn't matter which direction that the snorkel is facing, there will always be some percentage of water that gets sucked down into the airbox. There is no way to stop it happening unless there is some you beaut tripple double reversing air inlet which becomes impracticle to place at the top of a snorkel.

But if you where to fit a hiclone and create vortex effect the centrigical force of the water droplet laden air would would spin out all the water droplets to the sides and during the nano seconds all this is happening only dry air is sucked down the tub to the air box. LOL.
I personally think it would be impossible in physics. If professor Julius Somner Miller was still alive he would ask why is it so.

Damn , Mario I forgot that a hyclone can fix anything.

It is possible, It's just an engineering problem. The Sabre engine takes in air, dries it and cools it to sub zero temps in a fraction of a second. One of the problems was stopping the moisture from freezing and clogging up the refrigerant lines. They don't say how they do that either.
