It feeds up through the splash guard/air deflector to a coupling mounted in a hole I cut in the bottom of the resonator. Parts were < $10 at local Walmart. If you want the opening flush with the bottom of the guard all you need is [ame=http://www.amazon.com/gp/product/B000BQR8TE/ref=nosim/103-0376577-2277426?n=15684181]this[/ame].

TSiWRX Posted June 8, 2006 Share Posted June 8, 2006 ^ Maybe - but maybe not..... I've pretty much always had "slammed" DSMs, and a couple were jury-rigged with just this form of home-made cold-air induction (not really "intake," per-se) - none "sucked" water, probably simply as it never actively provided vac/suction, since it was simply ducting. And this was with vehicles operated in NE-Ohio, which sees its share of rather snowy/slushy and very wet weather, seasonally. What I did see via an engine-compartment versus intake-area (which was blocked-off with a home-made heat-shield) with such a setup is similar to having a heat-shield on our turbo - lower temperatures when the vehicle was in forward motion, and a higher rate-of-change of temperature drop. Does it actually add power? Who knows --> but it's a "fun" mod to clobber together, much like, say, either the intake resonator removal or exhaust "hog-spacer" mods. <-- I love Winky, my "periwinkle" (ABP) LGT! - Allen / Usual Suspect "DumboRAT" / One of the Three Stooges '16 Outback, '16 WRX, 7th Subaru Family Link to comment Share on other sites More sharing options...
TRS Posted June 8, 2006 Author Share Posted June 8, 2006 IBitsucksupwater The underhood snorkus and inlet into the airbox is still there so even if the end of the tube was submerged there wouldn't be any vacuum to suck up the water and I'd have to plow into deep water awfully fast to force water high enough to fill up the resonator and then the air box up to the bottom of the intake tube. It will ingest some rain (so does the snorkus) but I think only the small diameter droplets could pass through the resonator. I added a couple of additional small holes in the bottom of the resonator to facilitate drainage. Link to comment Share on other sites More sharing options...

That's pretty much the results I got doing a couple of preliminary logging runs. IATs were the same at steady-state speeds whether the new inlet was blocked-off or not. However, they didn't rise as much after slowing down (1-2 deg C lower) and they did drop quicker after accelerating. Testing was done at speeds of 45 to 75 mph, with ambient air temps 65-67 F per dash readout. Link to comment Share on other sites More sharing options...
TSiWRX Posted June 9, 2006 Share Posted June 9, 2006 ^ Once, and once only!, I managed to somehow see LOWER IAT/intake-area temps than ambient with such a mod on one of my DSMs. Total fluke due to some funky weather conditions at that very moment, but it was pretty nifty! Seriously, though, like I confessed, bro, I'm totally not sure if something like this would make *any* extra power - it was simply a fun mod for me (and will be again for Winky, once I gather the necessary components), and made *me* "feel better" about the car breathing in "cooler air." Good stuff you did!

PhilT Posted June 9, 2006 Share Posted June 9, 2006 I don't see how you can get any cooler than where the stock airbox draws air from, unless you pipe it in from the A/C air outlet Double Award Winning Legacy GT Wagon Link to comment Share on other sites More sharing options...
TSiWRX Posted June 9, 2006 Share Posted June 9, 2006 ^ I know, that's what's so funny! It was a total freak weather thing - I swear to God Almighty, that's what I saw on the readouts! - but you should've seen the weather...it went from sunny to pitch-dark, foggy, and stormy over the course of less than a mile's worth of road. I'd bet just about anything that it was some kind of weird temperature phenomenon at close to ground-level that caused the sudden "reversed" readings. <-- I love Winky, my "periwinkle" (ABP) LGT! - Allen / Usual Suspect "DumboRAT" / One of the Three Stooges '16 Outback, '16 WRX, 7th Subaru Family Link to comment Share on other sites More sharing options...
PhilT Posted June 9, 2006 Share Posted June 9, 2006 I guess if you had ground level fog, that would work. A little bit of moisture in the air works wonders. Double Award Winning Legacy GT Wagon Link to comment Share on other sites More sharing options...
