DIY Snorkel
« on: April 04, 2009, 09:52:23 PM »
Didn't like how dirty my air filter was.

So time to start making a snorkel, but not wanting to pay $200-300.  Mostly using 3" PVC, 3" tubing is big, so I went with the thinner walled PVC instead of ABS.

It's late, so I hope this like to the albums shows all the pictures.

In the front quarter panel is the air intake tube, and a large air box.  Junking the air box, and turning the tube around to face the rear.
I trimmed the tube opening, its about 2.5".  I cut a 3" piece of 3" PVC and cut a strip out.  Used adhesive and clamped the sliced PVC to the tube, this made the OD 3" so I could glue an normal piece of 3" PVC to it, then a cupling, and then a rubber cupling to join the rest of the snorkel.  Once painted and glued the rubber coulpling will help assembly and allow some access if needed.

The smaller 2" opening on the tube that will now be facing forward will be fitted with a little run, a 90, and a screw cap access hole.  This will give a small drainable section if I do get water in the snorkel from driving in heavy rain.  For this part I'm using scrap, so its not yet cut to fit and I don't have the access cap.

So, seal up the drain hole and cracks around the rubber fittings.  Putting what we so far have together leaves us at the step to cut into the body...

There's not much room in the panel.  There is one spot inside that has a grove on the engine side, this JUST allow enough room for the 3" 90 PVC (the 1/8" thicker ABS would work, but this is tight as it is).  Cutting a large elogated hole allows for the PVC to come through and up a few inches.

From here it's a simple 45 and up beside the window.  I bent some steel to make a bracket, I'll bolt the bracket to the piller, and then bolt the tube to the bracket.

I'll get some more pictures later.

As you can see from the Bondo, I had cut my hole way to big.  I'll try a picture of the hole with some measurements to make it easier for others.

I am not much of an offroader but what exactly would you need a snorkel that highl for......
do you guys actually get your tracker that deep in mudd and water that you would need to make the snorkel go up to the roof???.....is it just to avoid getting dirt and what not in the intake????

is the snorkel exhaust or intake...or both....and if its only intake what about your exhaust...SHould you not modiy your exhaust as well to avoid bein plugged by mud???????

I'll trim it later so it end around the roof or top of windshield.

The snorkel is just air intake and helps keep your air filter from being plugged with dirt, and water from getting in and damaging the motor (hydro lock).  The exhaust is under pressure, so it would push mud/water out.

The stock air intake is just behind your left head light in the body panel above the wheel well.  I'm not going to rush into and deep rivers or mud pits up to my windows, but I've been in ones up to/ almost past my bumper.  The extra bit of hight will help keep spashing water, mud, and dust out.  Less work cleaning the K&N filter, and less worry when I cross a river or mud pit.

unless the vehicle stalls... thats when water or such will flood into the exhaust. some guys modify the exhaust to go higher up as well but thats when you out doing real deep water crossings.

With the length of that snorkel or ANY snorkel really wont that reduce air flow....that air has got a long way to travel now.....(I in no way mean to put down a snorkel.....I am a daily driver of my 00 tracker.....this mod sounds like a serious offroader mod correct???) could of used one of those on my jeep when I went into that river awhile back......

the snorkel sucks the air in better than stock, i have found that it gives good throttle through the gears in a manual for any driving

Interesting.....on top of that the air sucked in is relatively cleaner and cooler......so maybe just more then some device to keep your intake above water ???? hey intake on the one side exhaust on the other lol :P
