Cold air induction

Got a question for you all. When doing cold air induction down to the lower front of the car, do you have any problems with sucking up water? Or is the setup not that well sealed? Like, if you drive through a foot of water, will your intake suck water into your engine?

when it utterly POURED down recently, and the roads got bogged in hell deep water, the splash up into my CAI was enough to drench my filter and stall the car. i had to limp (stuttering the whole way) to a servo and use their air compressor to blow the filter dry...

You could fix the problem by putting a vertical S bend in the pipe to the filter, if you have the space of course, that would stop most water getting up even a straight vertical length would probably help. I think *shrugs*

Ed, isn't your filter in a box?
What if the end of the pipe is submerged? Would it suck the water up?
Also, if you put the S-bend in, what happens when the S-bend gets full, and the other end is submerged?

A guy i know has an XR6-T and they apparently have a CAI right down near the front of the car. In the last decent amounts of rain he went through some 30cm high water and proceeded to digest 3/4 litre of water through the filter into the engine... luckily ford covered it under warranty

If you cut a hole in the bonnet, then set up a plastic thingy to pipe in the cold air, would that work? ie:
Or is that just over the top?

That's what bonnet vents are supposed to be there for. I've seen a set up like that, that was set with a magnetic catch which closed the vent when it was raining.
Other wise I think you'd be more worried about spray going in the filter and then once wet enough into the engine rather than sucking up water like a straw. If your using that A/C style flexable piping as you feed pipe I think it would collapse before it sucked water like that.

Problem with that Roman is that your then sucking in hot air from the engine bay, rather than a nice cool charge from the air. Also, I hear cops go defect happy with exposed pod filters.

If you make it all fairly vacuum tight, then wont it just stall when going through water? Or do you just make the setup in such a way that it can suck in air from alternate sources?
Also, as mentioned before, if you put an S-bend in your piping I don't think you would have to worry about water spraying into your filter. I would be more worried about water spraying into the bonnet vent induction setup.
Lambolica, how did that vent close? Swith inside the car? Or did it have some kinda rain detectors like the Jags do?

The bloke who did the closing bit was an "aquantance" of mine some years back who owned a Cordia and had a fibreglass intake vent that stuck up from the bonnet. after doing work to the car he wanted just a hole in the bonnet trimmed with stainless steel but was worried about rain just falling in and filling the filter box. After a night on the piss at my place piss farting around with my old RA40 interior. I mentioned that he should make a flap that covered it with a kink in the front edge of the flap so when going at speed the flap was lifted by wind pressure letting in more air. He was rather excited by this but found the obvious flaws in that concept, and questioned me more on ways around that. After a myriad of leaver concepts and pulleys and servos he came up with a magnet setup. After that I didn't see him for a few months but when I did again he had done it! I was shocked. Basically there was the flap which was a squarebox thing that either took air from above the bonnet when open and fell below the filter box when closed pulling air from the engine bay. the magnet setup was a little beyond me but it was along the lines of two electromagnets one that held it open the other held it closed run by a switch in the car that simply reversed the polarity of the magnets. opening and closing it. it was cool when he shut the car down as the vent flopped shut.
He wrote the car off in the wet a few weeks later

Wouldn't the setup in my diagram work fine though? Your not likely to get any water splashing up from that.

You'll get some no matter what, small enough water particles will follow the air flow the normal down the front must work alright otherwise people wouldn't do it all the time?
