Snorkelectomy how too?

Same as every other forum on this topic some say do it some say its a waste of time.

+1 on leaving ram air thingy in - or at least make sure you block the hole!

Ha even though I've cut mine out the only noise I get is a bit of induction type noise. Doesn't make my BOV make any noises. All I wanted is better airflow but still keep the system pretty stock. Wasn't looking to get boyracer noises. The snorkel thing is there more to keep the induction noise down for the little old ladies. Cleaner airflow has to be better!!!

I'm no expert so dont slice 'n' dice me. When I installed my pod filter immediatly the intake noise was louder AND the factory blow off valve was really obvious

Those pics look like you're now sucking in warm, engine bay air as well as air from in behind the guard. Should really blank off that hole so that the airbox is only fed from in the guard.

Doesnt sound at all louder.

dang! did you just try it out?

[Guest]

webup, whats the little hole for? in the part u covered, the 6mmish hole?

aahhh, thought they were urz to, my bad.

wounder if the hole is for a whistle affect lol

You are getting colder air from ducting through the guard - so thats a bonus, however slight it might be

[Guest dynofiend]

It usually needs about a -10C change in air temperature to make any difference to power. Its why I always laugh when I see induction kits which go out of their way to suck air from near the bottom of the bumper because supposedly air is colder at that height off the ground

[Carbon]

I said it was slight ;-)

However you also have to consider ambient temperature and heat soak of the standard vs ducted when stopped as well. I can certainly feel the extra 0.1 horsepower so mock all you want

Water drain hole as that is now the lowest point in the intake.

This is a 94 WRX, you cant just apply the same figures to every other Subaru using a similar intake system. The article also assumes (wrongly) that the intakes resonant chambers are purely for reducing intake noise which for me shows a fundamental lack of understanding of the original design.

Still, for a few bucks, its worth trying I guess ;D

[Guest dynofiend]

Id expect that the large chamber near the open end of the intake is for noise reduction, but the smaller one nearer the engine side is probably to do with generating or reducing a particular frequency to aid torque at lower rpms. Not that this thread has discussed removing this, but the article linked to briefly considers it as a possible future upgrade to further reduce restriction in the inlet system. That was what I was talking about mainly.

There is one final thing which again is perhaps worthy of mention just as a general point when modifying intake systems. It is usually a bad idea to run a single enclosed tube or pipe to a location close to ground level, because should you hit a large amount of standing water, then the water will get ingested straight into your intake and grenade your engine. Ive seen it happen with intakes at knee level!

[Guest]

hey got the 99 gtb and the two or three screws that need to be undone in the wheel arch that holds the cover infront of the air intake are plastic! when i went to unscrew the dam things the tops of them just gave way and now insted of a nice + there is is O so you cant undo it! HELP! haha

Side cutters to remove. Zip ties to re install.

+2 thats what i've done too.. screw getting da plastic xmas tree clips. cable ties work a treat and easily replaced too ;D

[gtlegacy]

ok so with a gen II rsb i had a pod on mine and i dont want one anymore lol do they come with thatair feed from the gaurd that the pics show the 99gtb does?

im guessing earlier on in the topic the person that covered thecut end of the intake in gaurd just ran it directly to the front? so really the intake goes from your feed at front through the gaurd wall and then into the cut off part of chamber and then back through the wall and into the afm ?

is there not a shorter way of doing it?

[Volcanix]

is it worth bell mouthing the intake pipe that was inside the white plastic thing that was inside the snorkel

ive got a pipe going from my factory airbox to my front bumper

[Guest]

Just an update on this if anyone is wanting to do this, I done this today, mainly because i wanted a noisier intake.

I have a Revision D Legacy and this was realy easy to do.

Results from what ive done. Intake sounds EXACTLY the same no increase in volume which was a surprise and disapointing, and definitely no BOV sound even when being caned

Im not sure now how valuable this mod actually is, but it is really easy and would rather do this than install a pod filter.

If you want to do this mod go for it it took half an hour after sourcing all the parts, i used 85? mm pvc piping from Mitre 10 the elbo cost $6 and i had a bit of strait pipe which i bell mouthed then glued onto the elbo.
