Jeep CJ Snorkel

[drummond]

This is a snorkel that I built last winter, I just never did a writeup on it.

For a long time I had wanted to do a snorkel setup on my Jeep. It wasn't so much for the fact that I was constantly going to traverse water that was over my hood and run mud that could be that deep. I wanted it for more of a security measure because some of the trails here in the Western UP and even Drummond Island can get quite deep in the spring. I had a couple factors that concerned me when I was designing the snorkel setup.

1. I did not like snorkels that went up the windshield of my Jeep. I have broken several windshields while wheeling, and constantly seem to find trees rubbing against my Jeep, and I felt that a snorkel mount in this location could be broken very easily.

2. Cost=Cheap. I wanted to build and design something on my own that would be simple, effective, and cost efficient.

So I started looking around at different possibly designs. I had already taken the heater setup out of my Jeep, so I began to investigate running a snorkel inside my cab. I researched this a great deal and decided against it, due to the obnoxious noise and smells that it can bring. I found that if I could intake the air somewhere off of the cowl, it would be much more beneficial. I brainstormed for quite a while, and found that a air intake setup off a stock Chevy K2500 would fit to the top of my carb. This was good because it allowed the attachment of some sort of tubing to re-route the air intake

At this point, I started looking at what I could use for an air intake box. I discovered a dryer vent setup (Home Depot), and dryer vent hose could fit my application. I was a bit sketchy at first that this was going to be a cheap way out...but if i did it right, it would look okay.

So I bolted up the chevy air intake on my Jeep engine.

I then attached a dryer vent hose to the end, with a custom PVC adapter in between, and I sealed it up really good. Then I routed the dryer vent line through the area that my heater core had once gone.

This is when everything got a little tricky. I wanted the intake portion to look clean, and have an almost "factory" looking appeal. How was I going to do this with a dryer vent? Well I cut a hole in my fiberglass body, and went to work. After many layers of fiberglass, sanding, and painting, it started to look like something.

This would allow good air intake, plenty of clearance, on a budget of under $30 complete.

Here are some pics of the snorkel setup on the Jeep. I can still fold the windshield down as well.

:thumbsup: Nice job brent

looks cool.

mine is a safari snorkel mounted to the pass side windshield. we shall see how well it holds up.

Interesting...i guess i don't see the point to run it there though

Interesting...i guess i don't see the point to run it there though

to keep it out of the wave of the initial "dunk" that occurs in the engine compartment when dropping into water holes. Also keeps the water from spraying up due to the fan. Also raises the intake level an approximate 10". We have lots of deep water here in the Western UP, and I have seen vehicles need snorkels consistently. Also helps intake cooler air for the engine. With the fiberglass body, the heat is well insulated, and intaking that constant warm air doesnt help it run the best. Runs much better now

Another reason for running it there. I have broken two windshields already to this point. I wheel tight, off camber, rocky trails that do not suite well to windshields. Conventional snorkels mount to the windshield, and this would not work for me

Looks good Brent! :thumbsup:

Looks good brent, good execution.
I dont like having the plastic one run up my windsheild, so i will be making a metal one soon. Its not easy to hide a snorkle on a jeep

Looks good. You got that factory look you were going for too.

sweet glad it works for you.

What do you think about venting it inside the tub...maybe where the glove box is suppose to be??

[drummond]

I have seen a couple CJ's this way, and I dont really care for it. Couple of reasons

1) I have found since it is a carb'd vehicle, the spell from the fuel is too strong for my like. It is quite easy to get some back draft of fuel fumes into the cab. Not something I really care to smell when I am wheeling.

2) Sound, I have found with having the four-barrel truck avenger carb on the v8, the sound of the air intaking is actually decently loud. I think this would become annoying every time I got on it, and have to have to listen to it inside the cab of the vehicle. Just my personal preference though.

2 good points...thx

My old co-worker ran his snorkel inside the cab. Noisy as hell. Granted, he was running a 454 with lots of horsepower. That, and it was only a mudtruck, but still, noisy. I can see if you drive it on the trails or especially on the road, it would get old fast.

I like the fiberglass work, but how much depth did you gain?

[mdswmich]

You should make an elbow for one of these for some more submergence...

I like the look. Good points about not running it inside. You are right about just getting it a little over the hood level. Most comes from the fan and initial rush of water. Did you do anything to your fan so it won't suck back into the radiator. We are going to be doing a couple local runs this summer and we will look you up. We could test out your snorkel on some property I own on the bear river. Actually I don't think anyone has ever made it to the rivers edge, the mud just keeps getting deeper and deeper and deeper. It gives the hell hole from the Swamp Stompers UP run a good challenge.

Ethan, I run a taurus fan so that I can shut it off with deep water crossings. The snorkel has worked out good, but I would like to do some more testing for sure. Let me know the next time you guys are going out. You can hit me up on here, give me a call at 231-838-2389, or look me up in the phone book. I live in town on Michigan St.

pffffff.......Drummond doesn't do mud.

:hehe:

[LuckyCharm4x4]

would that bring in rain at all?
