I have an eBay SRI and a breather, with the breather hose hole plugged in the intake tube.

When I turn off my car, there's a sucking noise in the vicinity of the SRI, like that last little bit of water going down the drain, for about a half a second.

Anyone else getting this? Is it just my intake backing out the air when my engine stops?

 

it's quite normal from what i've seen. my buddies type R in his CRX sounds like a dying noise from someones lungs when he shuts the car off =)

I was wondering about this post, thinking "of course it makes a sucking sound, it's pulling in air" but I'll have to admit I'm not sure why it would continue after shutoff.

Check to make sure your vac hoses are connected snugly, and that they aren't crimped or twisted. If you're concerned it could be water, remove the SRI and make sure there isn't any inside.

 

rentaslut's description is right. It doesn't make that noise when it's on, other than the normal loud intake noise, but when I turn it off, it's like a dying breath. A gurgling sound.

Maybe it's just that it's sucking in so much air that once it's cut off, that's the sound it makes... ?

Hoses are all ok, no water in the SRI. checked that already.

 

My RMR sri does this and when I ask the Mitsu dealership that sold it to me about it, they said it was normal. I have gotten use to the noise and I actually like the sound.

 

Huh. I can't believe I just noticed it, after having my SRI for months. Guess I shouldn't blast my tunes so loud....

 

its normal, my injen has been doing it since i got it in, i think its sounds cool.

 

Totally normal. I've had two different intakes, they both did it. It's just that last breath of air being sucked in.

 

Normal... mine does it too.

 

yeah mine to first time i heard it...i was scared, but lol the 2nd/3rd time i was like eh...it will be alright.

wonder what the turbo guys sound like when they turn it off?!

 

i believe that sound is made by the pressures inside your intake equalizing with the outside atmosphere. they make a hissing sound because they have to squeeze around the closed throttle plate. my theory anyway.

 

its totally normal my //RRM intake does the same thing. ive had it for a year. everythings cool

 

yea i love that sound..

 

mine doesnt do it...wait let me go start my car up so i can listen for it!

 

very normal - mine did it all the time, then i got a catback with headers and now i think it stopped, lol

(( for those who didnt get it, its still making that noise, only the exhuast cancels it out b/c its soo loud ))
