Ok so I was all excited when my Hahn intake came in today. I just got done installing it and suddenly when I start her up there is a loud "WAAAAAAA" noise coming from the engine bay. I checked everything 4 times, nothing is rubbing I even tied back the AC lines that are known for rubbing the intake. I haven't had the car for a week and I'm getting nervous to what could the noise be. I know it's hard to explain the noise via typing but it almost sounds like the turbo spinning? I checked and the intake piping is snug everywhere (thought it might have popped off the turbo). I don't know what it could be and I'm shitting bricks right now. ANY help would be awesome

 

it may just be the cold start surge happening, by the way WE ARE!!!!!!!!!!! PENN STATE!!!!!!!!!!! class 07

 

its not just the loud sucking from the turbo is it? when i first start mine its a loud sucking sound... but goes away after a few mins of driving or a rev.

 

Class of 09 I just graduated in May. So what do you suggest? Should I just let it run and eventually it'll go away? Has anyone else had this problem? I don't know if I'm over reacting but like I said I've only owned the car for a week!

It didn't make this sound before I put the intake on. That's why I'm worried. But I think it is the turbo making the sound. Is this supposed to happen?

 

Let it run and idle down on it's own. That's the turbo sucking air. Same noise here, and it didn't do it before the intake

 

yeah just let it run or get in and rev the engine a little. if it dies down then its just the turbo sucking air through the intake. mine didnt make this sound before the intake either.

 

So this is a natural sound that its going to make every time I start the car? Or just for now since I put the intake on? Sorry for all the questions guys

 

Yea mine sounds like a compressor on cold starts and you will hear it pshhhh out maybe once or twice. should be normal just make sure everything is snug and if u get a cel get it read and post the code up here. but i really wouldnt be worried about it to be honest

 

yeah i get it everytime i start the car after its sat for a while. extremely loud in my garage!! lol! but yeah its normal. but like he^ said, if u get a code get it checked out.

 

Thanks guys, turns out that's all it was! <sigh of relief>

 

same here, installed it on tues night, what a great sound it is too. love the intake

 

i can hear mine like eco in the piping at certain rpms, its kinda weird

 

completly normal. will prolly happen everytime on a cold start up.

 

I can't believe how much louder it made the bpv. I'm obsessed with it haha

 

so am i haha...i have a question. Did your intake come with a rubber piece that lines the hole that the intake tubing goes through to keep it secure in the whole and surrounds the whole pipe?

 

yup. glad u guys like urs. i dont like mine. mines coming off as soon as i can replace it.

 

what are you gonna replace it with?

 

either stock intake box and mod it.

or CIA intake

my AC line rubbed a whole straight through my silicone coupler. and my PVC vaccuum line was starting to rub thorugh my CP.

 

so I assume ur selling it?

 

once i find a replacement...had to put some "custom" pieces on it.

 

let me know when you do im very very interested

Its black right?

 

black. i have a custom piece to fit the PVC line so it doesnt leak whatsoever.

and the Hahn coupler is replaced with a thick ass fatty coupler from spectre.

 

Well im more then likely will buy it from you or im going to buy rissas so she can powder coat it and make it look pretty

 

up to u man.

id say buy rissas. idk when ill have the cash to sell this and get a new CAI. or time to modify the stock one
