Topic: cowl intake

[Jesse-James]

I'm not sure if better is the right word.  Perhaps no better.  Like I said, the wave will have a trough at the backside of the wave which will give you a little leeway.  If you're hitting the water fast enough or it's deep, the peak will rise higher then the baseline.  Which would then go over the hood.  (The front of the Jeep would still slow the progress of water.)

In any case my complaint isn't with the design as much as where he's got the input located.  It just looks bad.  The other thing I'm not really keen on is that there is no airbox to speak of.  He has what looks like flex hose going through the firewall into the cowl space to the cut off stock intake.  That would mean his filter is under the cap.  So if water did get into the intake, there is no holding area, it just gets sucked into the engine.

The other setup I've seen, which I believe was the first, had a airbox under the hood still.  This will at least hold some water back.  This is why ARB uses the stock airbox.  The input is low in the box but the output for the intake is high up.  This means the box would need to fill some ways before water gets ingested into the engine.  It's acts like a trap can.

I've seen some bad PVC and some good PVC home jobs.  Still without sealing up the diff, transmission, transfer case, distributor, PCM, raise the exhaust, etc...  having some positive pressure might even be an idea.  Although the other use for a snorkel is for high dust areas.  In that case you're trying to grab clean air where ever you can.

Another option is to go with the non-permanent setup like the Military Jeeps used.  You could have the intake go through the hood and attach the hose from the outside. (I think this is what they might be doing with the CRD Militilary JK's.)

I see what you mean now about the wave engulfing it, and as far as the airbox goes that's a given. Just used that pic for lack of choices.

As far as the military setup, that looks nice. Put it on when you need it, stays away from the trees when you don't. I like it.

Raising the dead here a little bit.  Jeffy, do you still have the pictures you put in this thread way back when? I like the idea of a removable snorkel that would use the stock air box.

here's a different one with the same idea.

thats cool I have seen people run it to the wiper motor area but that is a nice set up!!

In all honesty, if trees are a problem for a traditional safari snorkel, just point the intake to the middle of the vehicle, and you will be just fine.  Even down here in Costa Rica, I have had not a single problem with my snorkel and trees (or rocks or water).  I would go this way if I were you, not only because of the nice lines it has, but also because it is a proven method.  But like it has been pointed out already, keep in mind a snorkel does not turn your Jeep into a submarine; you still got to worry about  all the breatehrs (axles, tranny, etc.) and all the electrical (of particular concern is the distributor), and all the electronics (many a jeep has died here becasue the ECU had cracks and the water killed it; in fact, I always take an additional ECU on board during runs just in case).
