stock bov

[2-fast]

does anyone know why my stock bov is hella loud?? everything seem stock to me

 

[agarc023]

Have you heard a stock one before though? Im not saying they're loud. I just want to know if you have something to compare to

yeah i heard a stock one before my cousin use to have one and it's not loud at all but mine it's hecka loud

 

[scotyu]

I wouldn't hate it ... I love the sound!

 

[agarc023]

It may be leaking. Mine is all stock too, but under boost I hear it hissing

oh yeah and my turbo spool hella louder then his. does that mean it's boosted higher?

Shouldn't be if its the same car and they're both stock.

mine does have a manual boost controller and the last time i check it was set at 14psi. is that the reason why it's louder

I would think that it would have something to do with your car being louder. Do you have a boost gauge?

 

[2-fast]

i had a boost gauge once that's why it was set at 14psi

Thats good then. Maybe you should try doing a boost leak test to see if the noise is coming from a leaky hose or something.

too lazy

 

[agarc023]

hahah aren't we all

check to see if your bov is crushed compared to whoever it is that your comparing it too, that makes a noise difference

what do you mean crush

 

[knochgoon24]

what do you mean crush

You can't crush the 2g BOV. Are you sure it's the stock plastic one?

 

[gusu]

A crushed 1g BOV is typically when you put it between two pieces of wood and literally crush it with a vice grip. There IS math involved in this step you will see people crush them to little or not enough. I would not do this just to be one of the cool kids.

The purpose is it causes the spring to be tighter to hold more boost the negative side of this is that it does not open quickly under low boost and I've heard stories of it not opening at all. It can lead to compressor surge which kills motors and turbos if you don't know.

yes is the stock black plastic bov only

Dump tube inside the intake removed?

 

[nyTalonTsi]

Yeah if your completely stock, all pipes stock and your stock 2g bov is loud its probably leaking.

All my piping is stock, even still have the silencer between the lower ic pipe and ic, all i have is a k&n filter and its loud as ####. Found out it leaks at 10psi another reason why i can't get past 9psi.

the S shape tube that is connect to the bov and the intake?
