whats going on, im new to this forum, i recently bought a 02 wrx and im readyg to do mods to it. im low on money so this is whats first. im gutting the down pipe(free mod) and ive heard of removing the intake silencer. but with that, some said by removing it, the restriction of air flow decreases so much the turbo is pointles and can be removed. others said keep the turbo on the car which is what i want to do. finally, my question is this, can i still remove the silencer and gain any HP what so ever without any chances of running into problems. Or is the only gain from removing silencer the louder sound coming from the BOV? any adavice on what to do would be greatly appreciated, thanks

Whoah whoah whoah. . . .

DO NOT remove your turbo. Intake changes aside, the turbo is what breathes life into your engine!

Removing the intake silencer has but one purpose. . . to make the intake LOUDER. This will make the turbo spooling easier to hear, and the reciculation of air, via a bypass valve, louder as well.

You will see absolutely ZERO power gians from this mod. It's merely meant to "enhance" the driving experience by making things your engine's already doing easier to hear.

The intake silencer offers a slight resistance to airflow, but I would argue that it makes more of a difference on the non-turbo engines. So you would "only" be gaining a louder and more musical intake roar.


(Whoever said that the turbo might as well come off knows NOTHING about engines.)

Makes the turbo pointless I wish removing that thing gave you 70hp

i just removed the intake silencer and used a PVC pipe to run from the fender into the air box getting rid of that inch gap between the fender wall and air box. the ram air, snorkle hole, whatever it is, im planning on covering it to keep the warm air from the engine being able to get in there, or if if any of you have any other ideas? i no i can buy an elbow to use the snorkle but that cost 30 dollars, if thats the way you think i should go, then ill throw on a homemade elbow to fit. i was also wondering, if i cut the inake silence under the two holes that connect the snorkle and air box, i would then have an elbow there but without a bottom. could i then use the air from the snorkle and air from the fender without any turbulance or problems, this is the way really want to go and if i get your guys 2sence in saying it will still work and safe, ill do it. any replies would be great ,thanks

Any chance of a photo of your engine bay? Or a link to shot of a similar car?

It would help in understanding your question!

i could look for some pictures, i cant really take them myself, the silencer is in the fender, so. im thinking the way the silencer wrks is the air enters the snorkle at the front of the car into the silencer where it circulates, then i think the intake more sucks the air in instead of the air just being blown into it, its not like this removing the intake silencer adds any power, maybe i should put it back on, i can live without hearing everything spool up and what not.

ill look for something tho to give u a better idea

Removing the intake silencer is common practice on sportscars, most believe (as I do) it lessens the restrictions on air entering the filter box. It does no harm, it makes the engine intake sound louder.
I took a different approach so I could use the stock mountings. I got an identical intake pipe from a wrecking yard and drilled the heck out of it, so some air can come in closer to the filter box thus lessening the restrictions, I hope. Any air traveling through a pipe loses motion due to friction. Hook a 100 foot hose to your vacuum and see the difference; less vacuum and a harder working motor.

instead of buying a elbow , i just cut the silencer in half under the elbow on it, hooked it back to the car, this worked for me, sure i have a hole in the elbow inside the fender but fender air is just as good as the air entering the snorkle,, and im getting air from both places now instead of just one. its prolly the easiest way of doing this. if u dont mind cutting up the silencer
