the blow off valve is mounted on the aluminum piping between the turbo and the intercooler right? can it be mounted on the rubber like hosing between the intercooler and the throttle body? The reason I ask is that there will be times where I would want to remove the blow off valve w/ ease, and that would be pretty easy to remove. Now, if not, do you think it would be possible to get some sort of "T" flange, and cut part of the aluminum piping away, and mount it there, and if I want to remove it, just take off the T flange w/ the blow off valve, and put in a connecting aluminm piece in place?

can anyone recommend a better way for me to take off the blow off valve easily so that it will appear stock?

basically, would it work on the piping between the intercooler and the throttle body?

and, the higher the psi I want to vent out, the louder?
I'm running about 12psi daily on my 850, do you think that's enough to make a loud pssh?
I don't care about performance increase, just the sound..

Thank you again for all your help.

Oh, and i have heard that you need to replace the recirculation valve w/ a blank plate.. why? if the air is being forced back when the throttle is closed, and the blow off valve is venting it out, then it should never reach the recirc. valve right? then there shoouldn't be a need for the blank plate? that why if i take out the BOV, i will still have my recirc. valve.

Hmmmm, maybe I can help you out a bit on it. On my friend's Subaru WRX, the stock bypass valve is designed to recirculate ALL the excess air back to the use for the engine. Having a plate to block off the left open hose when using a 100% atmosphere venting BOV will prevent the engine sucking in unmetered air from that hose and causes the engine runs lean at that split second. Even a split second of running lean might give you a ping-ping effect.
The "wooosh wooosh" sound level you are talking about is not affected by the PSI level you are running, which means higher PSI won't give you a loud "wooosh wooosh" sound, but the flowing volumn does affect the sound's loudness. Let's say you have a 2.5" inlet pipe from IC to throttle body, that's usually where the BOV will be mounted, upgrade it to a 3" pipe will bring the wooosh sound a little louder than before.
