That valve could be allowed to vent rather than Re-Circ but that would sound cool but be really dumb.

Basically...

You want TURBO sounds... Go Get a Turbo...

and at a low psi that they run at. its not really needed

most is right..... only centrifugal superchargers, or a boost source before the throttle body needs them.... since on the ss, the throttle body is first, they are pointless. The main purpose of a blow off valve is to bleed off boost after the throttle is in the closed position, this allows the boost to escape, rather than back up into the turbo, they basically prolong the life of the turbo, by releasing the pressure, rather than the pressure comming back to the turbo.....
