How much pressure do you need to have behind a GReddy Type S BOV for it to be some what loud. My BOV seems to be really soft, and I was thinking that it needed to maybe be T's by itself? I have My BOV, Actuator & Boost Gauge running of the FPR . . . . could that be why it is so soft?

 

10 psi is nice and loud. 5 psi dont do ****.

 

you can adjust the bov to let more or less pressure through which in return will effect the loudness/ softness of the sound

 

would it maybe be louder if I T'd it up by itself instead of splitting a vacum source with 3 things? As far as adjusting are you talking about the bolt on the top of it?

 

First of all, don't tap anything off your fuel pressure regulator vac line. Any leak in that, and your fuel pressure will be toast.

Find a good source off the intake manifold, or make one yourself.
