sub snorkel

ok, so on my 07, the issue i had, was that when i took my truck for a swim, (pics of after, below) my air box filled with mud... i didn't hydro lock, thank god, but it did cause a little bit of concern... the issue was when the front end got wet, and splashing everywhere (the water level it's self wasn't up THAT high... anyways, what i want to do is fill in the hole that the intake into the box has now, behind the headlight, where the water was splashing into, and punch a hole of equal or greater size, through the side, and into the fender... this will do several things A) not allow hot air into the box, like a hole on the other side will, B) bring even colder air into the air box, as it will be sealed around the fender hole... C) not allow any water into the box, as the right fender has the inner fender around the wheel, so no splashing will get up there, and it's a long journey down to the bottom of the fender, and a much more indirect route for water to get into the airbox...

now, of course, i'm not going to be expecting this will work if i take my truck in hood deep water...

thoughts?

Got a buddy who did that with his Toy, seems to work fine for him but he doesn't go swimming with his either though. IIRC, most stock Suzuki Sami's route their intake this way as well (I believe my 88.5 did). Its gotta be better than coming in from behind the headlight for sure.

You'll probably get less airflow into the airbox but there'll be less chance of water splashing in. LR

i don't want to slow down though... the speed is what makes it so much fun! the guy at the 4x4 shop said i should get a cone filter and a water sock... which is a possibility... i might buy one of them and put my drop in, in it...

i know all late (FI) fox body mustangs did it that way... the K&N CAI kit puts the filter in the fender, which is where i got the idea... why do you say there might be less air flow into the box? i'm also thinking about putting like 4" ABS for the duct between the box and fender

Because, airflow through a fender (assuming your inner fender is properly in place, which I'm pretty sure it is) is less than being directly behind the headlight which is open to the forced air of driving down a highway. There's more than enough air in the fender to feed your engine, its just not a positive rush like being pointed out the front thats all.

3" ABS (or whatever size the intake hole on the box is) would be more than enough, I'd personally remove the fender and route the ABS back under the fender and dump it up under the cowl below the windshield and put a bit of a downturn on the pipe there, I think you'd essentially build yourself a pretty good snorkel at that point without it being obvious nor an eyesore. Snorkels look cool on buggies, they look pretty ghey on stockish trucks. LR

I'd make a snorkel and run it as high as you can inside of the engine bay where it will still get good air flow.

Have you extended your vent lines on the differentials? If not, you need to do that too.

I Can't see any problems with doing that with the airbox, It should would work pretty well, especially if you made a tube rather than just a hole going out inside the fender or anywhere with clean and cold air. A cone filter with one of those covers would do the trick as well. By the look of it you should be investing in a full snorkel! haha, or a boat! I just installed one on my friends Land Cruiser, not that he needs it he just likes to pretend like he does! lol

I don't have any pics of them, but with all of my previous Ranger I always just sealed a run of 3" hose or pipe to the airbox and ran it to the back passenger corner of the engine bay and installed a splash shield around it. I've literally had water wash over the roof of one of my Rangers in a creek (passing Jeep on 35s submerged me for a couple of seconds!) and it never sucked a drop in. There's a huge air bubble that gets trapped under your hood and it takes a bit for it to escape so the engine survives on that for a little bit.

The biggest disadvantage is that you're always sucking in hot air which is bad. If you're willing to drill a hole in the your inner fender than you mind as well complete it and run it up to your cowl. Its the cleanest one of the bunch and it doesn't leave a bunch of piping crowding everything under your hood. LR

the water it's self wasn't THAT deep, several of the times (in that same hole) it wasn't even to the bottom of the door... it would never have been above the DSG on my rockers, for sure...

only reason i don't want to do that, is how everyone has been saying a snorkle will steal your power from you... the only other thing i might do then is something like put this...



in the stock hole, and then my new one, then buy one screw in plug, so i can run the airbox like stock, but if i am planning on getting wet, i can just move the plug from the snorkel duct to the headlight duct, and problem solved...

There's two things I can think about it: stock airbox (especially with splash guard removed) will net you the most HP, especially in the higher end of the RPM band. However, having a snorkel will kill your top end a bit BUT you will gain torque, especially right around the 2000 rpm mark (where the SOHC 4.0Ls kinda lack it). Its kinda the same trick used on the BMW 2002s back in the day to increase torque (long narrower tube to cause the intake air to be compressed a little, effectively charging it a tiny bit). Better for crawling and towing.

Realistically? I doubt you'll really notice a lot of difference except under heavy acceleration. Fuel mileage might change a little either way, don't exactly know how. However, this has got me thinking about doing a cowl snorkel on mine though, shouldn't be harder than dragging out the holesaw and gluing together some ABS pipe, and realigning a fender. LR

biggest problem is, i drive 85km a day commuting for work... plus when i go boarding... last wednesday, i put 400+ km on my rental, just go boarding, and i go boarding (albeit not always to the same hill) every set of days off i get... i've put about 12000km on my truck since i got it at the end of sept. so gas mileage is a big thing to me... 1mpg i notice, financially, in a month

so i'm thinking this dual intake system might be the best. See any issues with it?
