Yeah I have a 1999 Si EBP and I currently am running a Password whale ***** and a N1 catback. I was driving it tonight going about 40 in 3rd shifting to 4th and I heard a weird noise coming from the intake. It almost sounded like a blow off valve releasing boost. Anyone else with the whale ***** ever hear that?

 

i think i have heard of other people running like short rams or cold air intakes that have said something like that. i have no clue what it could be tho.

 

I hear it when I turn my car off, its like a vacuum sound.

 

i hear it too when i turn off the car got me wondering...haha

 

its normal and to be expected with any improved intake system. you are sucking in a lot more air so you hear it every car i have ever heard with an aftermarket intake has made that noise

 

Make sure that all vaccum lines are still attached also check throttle body for loose springs or anything loose on the mateing surface between the TB and the Intake manifold

just some suggestions

 

normal

 

if you want to get rid of the sound, open up your iacv a little bit.

 

 

try it...but dont feel stupid after you find out it works...it happens even to the best of us...

 

The sound might go away, but that doesn't mean you've fixed the problem.


OP: Do you hear the sound if you hold the throttle steady? If so, it's either vibration/resonance (which is not unusual with aftermarket parts) or a small vacuum leak. If you only hear it after closing the throttle, it's normal, and there's nothing to worry about.

 

yea that's a great idea...



sigged, this is classic

that's like saying if your fuel pressure is too high to just get rid of the gas cap. lol

 

hahahaha....ohh boy....great ideas here....


My AEM short ram has been on for about a year and a half now, ive gotten it to the point where if im between 14%-20% throttle pressure (VAFC2 gives exact read out) it whistles, on cold nights, its REAAALLY loud too....lol....this kid i gave a ride home one day didnt believe my car wasnt turbo cause i kept doing it in every gear....pretty funny....

 

Never heard it that loud. Damn.

 

I wasn't complaining lol. Personally I think it sounds amazing but it caught me off guard once I realized that it happened almost every shift.
