| All right, the time that a BOV is useful on any SC car is when you take your foot off the gas, the second you do that your butterfly in the throttle body snaps shut. The engine RPM don't fall immediately, they take a second or two there for the compressor is still spinning and there is pressure being crated between the TB and the supercharger. in this situation you could use a BOV, BUT the main reason that they are used in turbo systems is because that boost created by the turbo still spinning will create quite a bit of shock to the system, and over time screw up your seals and bearings in the turbo. The issue with the supercharges is that they are more durable and will slow down much faster, its faster not instant, there for its not needed, so a BOV could be used but vital. The main problem is that most SC bolt right onto the intake manifold and there is no piping to mount a BOV, this is depending on the SC you have. If i had a SC car id give it a try cause it cool, yeah people think that just having a BOV for the sound is lame and a waste of 3 bills but its up to you, hope this all helps
