Hi, since about one month i heard weird sound from my BPV i think. I don't hear it when i roll with the stock air filter. When i roll with my short ram it sound crapy sometime, when ulling about to 3000 rpm and i let the trottle off i hear a sound ( TOUP ) pull again let it off and i hear this ( TOUP ) Sound... like a closing valve or something. I'm an electrotechnician but i don't know why on my car i know nothing i don't know even which component is where! also, when hard pulling till 6000rpm release the gas, and i heard a ( FFOUUUIINNN ) sound off my short ram.... pretty sucking, i've film it but it's pretty hard to understand in video. I'll post it althought. Last day i've put back my stock air filter system, i did not heard it again but when i remove the vaccum hose that's going to the SRI i still hear the TOUP sound...
I will try to have better image of my problem. I need help! It pretty suck!

In the first video at 44 sec. we hear the FOUIIINNNN...

Sounds perfectly normal to me. Because you no longer have the stock airbox and intake system, you are going to hear all the sucking and wooshing sounds the car makes.

 

[samlessard]

I know... but this is not the wooshing sound! ..... The sound quality suck.. but give attention to the 44 sec in the 1st video...

 

[samlessard]

in the second and the third video, we hear greatly after each wooshing the TOUP sound....

It sounds normal to me...

 

[Drewfusss]

[samlessard]

Sam first off swearing isn't really necessary,especially if you want help on the situation. and the sound you are hearing is just the valve closing fully, i can hear what your saying but there is absolutely nothing wrong.

I think what you are hearing is the BPV valve slapping back down as it resets to vacuum i could be wrong, just a guess.

 

[samlessard]

This is the hellp i expected!!!!!!!!!!!!!!!!!!!!!!!! Thanks you! Do you know more about it? How could i chek it

 

[samlessard]

do you know where the valve is located?

That sound at 44 seconds is the BPV doing its job. It is recycling charge air, the reason it is louder with the pop filter is that the baffles in the stock intake system aren't there to disrupt the sound.
