RE: NEW TO THE BOOST WORLD
Superchargers have bypass valves that re-circulate the air back into the intake track so that way your car doesnt lose track of the air already accounted for by the MAF. You can run a blow-off valve or vent your bypass valve into the atmospherre for that WOOOOOSH sound but you will need a flow-thru MAF and have things tuned a little differently.

RE: NEW TO THE BOOST WORLD
SlvrOhTwoGeeTee, you beautiful bastard! I was thinking about that exact thing earlier and wondering if I could do it. I now know I can. Can you go in more depth as to how I can set that up? I haven't bought my MAF for my Vortech yet, what do I need to do to get that sound you're talking about?
And to the OP, thanks for asking the question I didn't have the ***** to ask! (I thought it was a dumb question)

RE: NEW TO THE BOOST WORLD
yea too bad nobody knows how to tune it this way... and that fuel dump is bad for a stock motor
ive been down this road many times.. if you get to work right, let me know...
also the bov on s/c has been shown to decrease performance... anybody else get these results?

RE: NEW TO THE BOOST WORLD
Can someone go in depth and explain how this works, or how it won't work too well? I would love to put that on my car and I'm almost willing to take a drop in performance to get it. I don't know, can someone educate me a bit more on the subject?

Blow off Valve 101:
When you let off gas and close throttle s/c is still making boost. That boost needs to go somewhere.
ByPassValve will dump it out and put it back into the system just IN FORNT of the s/c and after the MAF
it does this since the MAF has recorded that air, so it needs to stay in the system
Blow off Valve uses a blow thru MAF that is behind the s/c and reading boosted air.
Now you can put BOV behind s/c and in front of MAF and it blows off excess boosted air directly into
atmosphere before it has gone thru the MAF meter.
If your MAF is after your s/c you already have a blow thru.
If your MAF is before your s/c then you have to do what they say and get a blow thru MAF
for that swish pop-off sound
