Re: snorkel performance effects

Several people probably have some input but have been tied up with holiday stuff. Surprises me that nobody has chimed in for a week, though.

Re: snorkel performance effects

I do not have a snorkel on my old 84 cj but a club member has one on his tricked out tj. It works well in the hyper dusty conditions that are a near constant here in Texas but recently he was at the Candian River (18 miles north of Amarillo) playing with his new tj and decided to cross the river. The river normally runs about 6 in. deep but because of recent rains it was runinng about 6 ft. deep. He thought, "no problem, I've got a snorkle." His jeep was submerged about 5 hours before being winched out by another club member phoned at home to come make the rescue. Moral of the story is don't wheel alone and the snorkle doesnt convert tour tj into a submarine. [img]images/graemlins/wall.gif[/img]

Re: snorkel performance effects

Fairly Standard over here (Safari Snorkels) I haven't got a TJ and have no probs on mine CJ7 360 V8, My Co runs a TJ with no probs and so does the other DSRT TJ no probs.

Like swadesbcglobal points out there's a lot more to it than just wacking it on.
I have a dizzy that has compressed air that runs to it, The breathers from the Diffs/Gearbox/Tcase run to the snorkel (in and up (up to create positive pressure). why PP well it to help stop water ingress when you enter cold water (PP can also be plumed to the Dizzy). Plug leads are all siliconed around all the Lead joints and onto the plugs and dizzy.

To test if a Snorkel is fitted properly place a plastic bag over the Snorkel intake, if the Jeep stops you've done it.
If it struggles on or you can hear air entering through a joint try again........
The only thing that is then over looked is the Exhaust mine is low but I keep the revs up, if I stall I don't try and start the engine till I have winched out of the river striped the plugs out and checked for water, pos change oils..

Re: snorkel performance effects

My big question is the effects it will have on everyday driving (ie is my mpg gonna drop even more!) I would also assume that it will increase engine responsiveness, but just wanted to verify that.

thanks all

Re: snorkel performance effects

If it is the safari kit, you might gain a little in the mpg department, but it will almost be negligible. With the snorkel intake facing forward, at highway speed you'll notice a slight improvement in acceleration due to having cold air pushed in. You will not lose any mpg with the kit. I'd also get a k&n for your airbox for even better flow.
