thatswhatshesaid Posted August 19, 2008 Share Posted August 19, 2008 So, I've been thinking about the snorkels others have built for their Subarus...and I really want to make one. Problem is, my car gets seen a lot by my clients at work and I can't have ABS dangling off the side of my car if I'm to look at all professional...so here is what I need help with: I want to build a stealth snorkel setup similar to the ones on Humvees. I drew a picture: [/img] The red is the basic path of the stock intake. It is an ingenius design by Subaru. Ram-air. Awesome. And it is pretty high up off the ground. The problem is, that's the first place to get totally douched with water and mud when bombing puddles, etc. The light blue path is my proposed snorkel design. I could remove the elbow on the airbox and form ABS or some other tubing to guide the tract upward to the back of the hood/cowl area. This plastic section can easily be cut to facilitate the addition of a Hummer-type intake box/cage-thing. I will need to hack through the firewall section a bit, but that doesn't bother me. My plan is to have this stealth intake mounted permanently (it will look bad-A to anyone who understands it) - pokind slightly out of the cowl area, but retain the ability to mount a long snorkel tube to it, should I choose to take the monster through the deep stuff. Any ideas? Suggestions? Thanks, guys! - Tyler Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted August 20, 2008 Share Posted August 20, 2008 That area under the wipers is where the windshield drains, so chances are you'll get more water there then you will in the stock location Quote Link to comment Share on other sites More sharing options...
j2coe Posted August 20, 2008 Share Posted August 20, 2008 I always wondered if you couldn't do something like that with the scoop. same kind of thing with the intercoolers but air intake. I guess that isn't a 2.5 though no scoop. Quote Link to comment Share on other sites More sharing options...

I guess that isn't a 2.5 though no scoop. There is definitely no scoop - it is a 2.5, however. It's a 2000...no scoop on any models that year. 777 - There must be a way to divert the flow of water away from the intake tract...perhaps if it were elevated an inch or so. The area will be sealed around the base of the "protrusion"...like, with silicone or something. Quote Link to comment Share on other sites More sharing options...
thatswhatshesaid Posted August 22, 2008 Author Share Posted August 22, 2008 Any other input? What should I make the protrusion above the cowl out of? Quote Link to comment Share on other sites More sharing options...
thatswhatshesaid Posted November 15, 2008 Author Share Posted November 15, 2008 I'm reviving it...any ideas? I'm going to work on the snork idea again. This is gonna be sweet! Quote Link to comment Share on other sites More sharing options...
frogstar7055 Posted November 16, 2008 Share Posted November 16, 2008 (edited) I'm reviving it...any ideas? I'm going to work on the snork idea again. This is gonna be sweet! I did this to my 01 Forester. http://www.subaruforester.org/vbulletin/f102/cai-half-snorkel-41252/ It has worked fine. Everyone will tell you "it will get wet,to much air turbulance,blah blah blah"but with a K&N air filter you will have no problems.

thatswhatshesaid Posted November 18, 2008 Author Share Posted November 18, 2008 Thanks! That is exactly what I mant to do! (And here I thought I was being innovative...apparently someone else beat me to it!) One question: Where is the end of the intake? Is it up in the windshield drainage area? Do you have any more pictures or tips? And what kind of flexible hose in that you used? Again - thanks! You are a hero! Quote Link to comment Share on other sites More sharing options...
frogstar7055 Posted November 19, 2008 Share Posted November 19, 2008 (edited) Yes it pulls air from the windshield drainage area. The hose and the flange is from an auto parts store. was easy to do and will stop me from hydrolocking and blowing up another engine. http://www.subaruforester.org/vbulletin/f98/i-warned-38272/ Edited November 19, 2008 by frogstar7055 Quote Link to comment Share on other sites More sharing options...
thatswhatshesaid Posted November 19, 2008 Author Share Posted November 19, 2008 Thanks! Do you, by chance, have any photos with the hood down? I'd like to see what it looks like in the drain area. Quote Link to comment Share on other sites More sharing options...

That picture of the flange is inside the drain area. These are the only other shots I've got with the cover off the windshield drain area. Their are no vent holes in the cover directly above the inlet flange in the cover. With the cover on and the hood down it looks bone stock. You will have a distinctive ROAR when you hammer the gas peddle but sounds normal at speed or during mild acceleration.

thatswhatshesaid Posted November 21, 2008 Author Share Posted November 21, 2008 Oh, I see. Totally stock looking from the outside. Sweet! No water issues at all? That is surprising. And comforting!

JT95 Posted November 21, 2008 Share Posted November 21, 2008 I always thought it'd be cool to use the hood vents off an Impreza RS or OBS, remove the shield from beneath it, and run your intake ducting directly to the open vent on the passenger side. Not too many people wanting to cut a couple holes in their hoods though... Quote Link to comment Share on other sites More sharing options...

I wonder how ONE RS/OBS/22B vent would look on the Legacy hood? Would that be ricey? Who can photoshop that for me? Quote Link to comment Share on other sites More sharing options...

I would think this wouldn't be a good idea without some kind of drain in the intake tract under the hood,otherwise it would fill with water when the car is just sitting in the rain.

Some kind of drain/water diverter shouldn't be too hard to work up...did you make something like this in yours? Quote Link to comment Share on other sites More sharing options...
JT95 Posted November 21, 2008 Share Posted November 21, 2008 (edited) Some kind of drain/water diverter shouldn't be too hard to work up...did you make something like this in yours? Well, rather than running the duct straight to the hood vent, fab a "box" that is open on top and seals against the hood when shut. Run your ducting into the side of the "air box" at the vent. Water would fall into the box, and not be falling directly into the air duct itself. I don't have photoshop, so instead of putting a vent on a Legacy, I just painted over the other vent and scoop on an OBS: I think I'd go ahead and do both. Keep thing symmetrical. Although, you could consider putting one of the mini-scoops over the solo-vent. I was talking about just a universal mini-scoop, but these are made for the Impreza hood vent fitting, which doesn't really do anything easy for a Legacy owner, but anyways: http://www.etsracing.com/3..jpg http://tyneteestuning.co.uk/images/DSC00090A.JPG http://tyneteestuning.co.uk/images/WAGON.jpg http://www.etsracing.com/001%20006.jpg Edited November 21, 2008 by JT95 Added additional info Quote Link to comment Share on other sites More sharing options...
JT95 Posted November 21, 2008 Share Posted November 21, 2008 OK--here's another Impreza I fixed with only the mini-scoop. The solo-mini scoop looks better than the solo vent. Quote Link to comment Share on other sites More sharing options...
frogstar7055 Posted November 21, 2008 Share Posted November 21, 2008 Some kind of drain/water diverter shouldn't be too hard to work up...did you make something like this in yours? Their are drains on either side of the winshield drain area. I drove it in a drenching downpour, I opened the filter box and the filter was dry. All I know is what I did works and I won't suck up water in a mud pit and blow up the motor again. Quote Link to comment Share on other sites More sharing options...
thatswhatshesaid Posted November 22, 2008 Author Share Posted November 22, 2008 Awesome! Thanks frogstar. Yous a hero! And I like that scoop on the Imp, but I don't know...I think the cowl area is a little safer...albeit not as awesome looking... Quote Link to comment Share on other sites More sharing options...

frogstar7055 Posted November 22, 2008 Share Posted November 22, 2008 The filter is in the big black box. My 01 is map based,maf systems would need more routing of hose to make it work. Quote Link to comment Share on other sites More sharing options...

Yeah, my Sube is maf, so you have to take that into consideration. I'm actually going to fab up something with an open hood vent. Honestly, not sure if sucking in cooler air from outside will make that much difference for a 2.2, but heck, it's fun to piddle and experiment...

Make sure you have drains on any hood type scoop, otherwise your engine may drown. The fresh air intake at the cowl actually gets more air then a hood scoop will. The sooby scoop is in the slip stream to some degree, but the base of the windshield is a high pressure spot, and will function better. nipper Quote Link to comment Share on other sites More sharing options...
