Snorkels

[jmorris6689]

I was just wondering where i could find a reasonably price mantec snorkel for my 01 disco 2. Im really getting tired of sucking in water an ruining my mass air flow sensor.

"Reasonably Priced Mantec Snorkel"... no such thing.

X2 on the Mantec - - 4x4 exchange has a Southdown snorkel for a $350
Someone school me as to how much deeper a snorkel allows a gas powered rover to go. I've removed my intake horn on my air cleaner box and replaced it with a 3" 90degree elbow turned upwards. I've waded my D1 in water to the hood with a bow wake but never had issues with the water making it to the mass air flow. Truly on a gas motor how much deeper will a snorkel allow you to wade. If you go over the hood for too long or stop even with a snorkel won't your electronics fail. Snorkels look fine, don't get me wrong but will this truly fix the issue? Best of luck finding one but I am curious about actual function.

It seems to be pretty much a universal opinion that a snorkel's primary purpose is to allow a truck to go deep water wading, and it certainly would be a good thing, sucking dry air while stream crossing. The truth is, that the main reason to take your air from up high is that if you do any offroading in dusty climates, such as logging roads of Maine, where the dust is so fine you MUST wear a mask, the snorkel gets the intake above the dirty air. The second reason is that the air under the bonnet is over 150 degrees F. and the hotter the air, the lower the density ( the lower the oxygen, the lower the HP, duh?)
The Southdown, and most others get the intake up out of the dust stream, but the Mantec is the only one that uses a cyclone seperator top. The vortex created by the velocity increase going into the cone, forces dust particles right out the seperator vanes in the top. Follow someone down a logging road and you'll see the cyclone spin right off the top of the snorkel head.
People generally want these accessories to look cool and 99% of the buyers will never use them, let alone understand why they work. Another truth is, if you're getting deep enough to get water into the stock airfilter inlet, you'll have other electrical issues before long, not to mention the rust from trapped moisture.

The D2 mantecs are hard to come by. The safari snorkel is easier to get.

Mantecs rust.. Safari are HD plastic of some kind. Mine feels like a rock.

It's true that the powder coated pieces of the Mantec package do rust over time. The wing mounted piece on my 110 is now 4+ years old and has a spot or two bubbling. But the bottom line is that the Mantec design of top is far more effective at getting the dust out of the airstream, Before it goes down the pipe to the filter cannister. The proof of this is the long-term cleanliness of the filter.
Apart from the coarse screen across the inlet of the other makes, keeping big bugs out, they just don't prevent the dust from entering the system. The worst of these makes are the ones with the 'horn' top facing into the direction of airflow. Most of the raised air intakes are designed for appearance rather than efficiency.

I don't mind dust, That's why I have an air filter. Its all the water I'm worry about.

[Capt. Ron]

I've never been on a dirt road where the dust did not go above the roof of the vehicle...so pulling in air that is dust free is just not going to happen.

Adding a snorkel to your Disco is only part of the equation. This is just my opinion, but if you're getting water in your MAFS, you're either hitting the water hazard too fast, or it's too deep to be messin' with. Meaning it will end up causing problems with other components if they're not protected.

I'm a puss; I don't like deep water anyway.

[Jupiter Rover]

Yeah.. my carpets got wet last weekend.. At least my intake didnt suck in any of the water. Thank god for my safari.

[TerryS]

Pete, with all due respect, It's not what you mind, it's what your engine minds. I have heard all the arguments about paper VS K&N, and anyone who has spent a serious amount of time offroad in VERY disty climes will tell you a K&N is the last filter you want to be using there.
If you take your disco out deliberately to get wet, you need to do a little reading up on the subject. If your carpets got wet, you doubtless had your windows open, instead of what you're supposed to do, close all windows and put your outside air vent blower on high. What a vehicle can do, and what you do when alternative routes are available are two different things. I have yet to see a DD disco in the US, (i.e. petrol) properly prepared for deep water fording.

Ron, if you're driving in a dust cloud that high, you're not likely the lead vehicle, and you're following to closely to stay out of the cloud. I can go down the Golden Road at 50 and the dust will not rise above the bonnet, however I can guarentee the dust beneath the truck is being sucked up into the engine compartment.
I agree with you Ron, if a truck gets a SLUG of water up the air inlet, in a conventional under bonnet airfilter box, he was in too fast and too deep. Nonetheless, the SLUG of water is substantially stopped, or dissipated by the filter element itself. Water VAPOUR downstream of the filter element generally won't hurt the air sensor, and the engine won't die either. The vortex of air which causes a hotwire airflow sensor to vary it's resistance is not directly in the airstream, so I discount the stories of 'going through MAFs' as the same bravado as "I pulled an 18 wheeler through 6 feet of snow to and I forgot to lock my transfer case. (or other of the typical testosterone bs stories )

Im not a dumbass. Windows were closed. Just forgot to seal up all the cracks. I live in south florida not a desert.. There isnt much dust. I have had my K&N for almost 3 years now.. No problems. I get better airflow. I heard All the myths about K&N. And that is exactly what they are.. MYTHS. But in a dusty situation it makes sense why a dry paper filter will work better than a K&N. I use my K&N for better air flow. The mantec to me is like breathing out of a straw.. Thats why i drive with my snorkle head facing into the wind to force the air down which gives more airflow as opposed to facing it in reverse were it has suck for air.. eh who cares.

I know how to avoid the deep spots, the spots you get stuck in.. But whats the fun in that. I'm not on an expedition trying to reach a destination. Just out to have fun. I love the flow my K&N gives and the functionally/looks of my safari. I just got to remember to seal up my disco before I wade that deep again!

[TerryS]

If FL is not as dusty, as you say, then the K&N is a good choice, it's just no good in very dusty areas. However, water on a K&N filter is like water on any oily surface, so keep it clean if you're likely to get water into the airflow. You shouldn't need to seal the bottoms of your doors (duct tape works great, but makes getting in and out through the window a bit of a pain.) Just put your blower on high. Unless you have major gaps in the door gaskets, it should be enough to put the cabin in positive pressure.
I'm not acusing you of being a dumass, don't be so defensive. You have apparantly not seen the comparisons of airflow through the Mantec system, and they don't use a directional head anyway. It draws air in from the entire bottom surface and, like all cyclone seperators, creates a velocity increase. At the speeds anyone would be traveling through water, it makes no difference which direction the head faces on those raised air intakes with 'horn' type head have. Whatever works for you

[Jupiter Rover]

Oh.. I completely had the wrong idea of the mantec..
What do u mean by the blower? Do you mean turn the A/C on high?

Sorry I wasn't trying to be defensive. I was just in the water for so long... that the water slowly gurgled its way in. Everything is dry now. But that was a one time thing.. I don't think I'll wade that deep for a while. I don't want any damage..

No, just put your heater in the fresh air position, and turn the heater blower on high (Obviously with the temp control all the way down.) Keep all the windows shut and the blower will create enough positive pressure, to pressurize the cabin, so that if there is a leak in a door seal, the air will be going out, rather than the water coming in. It goes without saying, this technique doesn't work worth a damn in a soft top,
