BOV vacuum line question

[POS_Tsi]

Recently bought a talon tsi and has a few bugs to work out, should vacuum line be hooked up to something? (the vacuum "nipple" that doesn't have a hose on it)

And I know the BOV needs recirculated

what brand is it? whats the line already coming off of it go to?

That nipple should be left open as you have it. That is a knock off Greddy Type S by the looks of it at that angle. Do a boost leak test to make sure that BOV doesn't leak.

What is that second nipple for. My legitimate greddy has it as well

 

[POS_Tsi]

Yeah its a knock off Type S BOV

The other line leads to the under side of the intake manifold towards the middle of it

What is a good quality BOV in your guys' opinions? I will be on the look for one here soon. The fast and the furious "pssssh" is "cool" but even on the stock turbo running approximately 15psi I can hear turbo flutter now and again.. Is that driver error? or a crappy BOV?

 

[LiquidX]

The flutter could either be from a leaking BOV (bad diaphragm) or it's just improperly adjusted. Properly adjusted, the BOV should be closed at idle.

In my opinion, I would go with either a TiAL or TurboXS. The TurboXS universial BOV is setup to be able to be ran in any configuration with it's available attachments. A

TiAL, being USA made, is a high quality BOV which will vent out all the pressurized air instantly on just about every setup. 1 vacuum line, no adjustments needed, just order the correct spring and all is well. Even with a vented TiAL, it sounds much better than how the Greddy RS sounded being vented. It's a more subtle sound which isn't annoying. Put enough air through it and it will become loud enough for any vent boys wet dream.

Thank your opinion, I will most likely will go with the Tial, Iv'e heard nothing but good things about them.

For now though, how would you know if the BOV is closed? I have a feeling that the PO didn't adjust it correctly, looking at his other work he did to the car..
