I drove down to Vortech this afternoon and picked it up, they're local. The 1.5" dia. pipe & flange I had my muffler guy fab, the Vortech BOV is $250. After talking to Doug@ECS and a few others in the C5 FI forum, this maybe the one! I just couldn't bear the Hyperboost fluttering noise any longer.

Jeremy, Richard and others
Since I started this thread to get some help I've been following its new path on the BOV. Help is once again requested as I learn more about the supercharger I installed. What is the BOV (Blow Off Valve), see I do know what the initials stand for?
And, where is it located? I saw the picture that was posted of the OEM and the aftermarket one, however I can't seem to find where it is located. It under the shroud or someplace so obvious that I'm overlooking it?
Also, what is this fluttering vs whoosh sound thing?
Sorry to be asking questions, but I'm trying to learn along the way. Like you, I want to maximize my investment and get the most out of my car.
thanks,
Jeff

the fluttering is when you down shift lets say into second at around 45, its like a fluttering bag sounds its compresser surge from the blower which is very normal for cent blowers, the whoosh would refer to the blowoff of air when you go wide open then let off. and yea bov is blow off valve
oh and as far as location goes its a sub pipe off of the main below the blower.

Thanks, nice, easy to understand explanation. Funny, I don't recall hearing anything that sounds like a bag fluttering, I guess I'll start listening for it. And, no wonder I couldn't find the BOV

Initially, on the ProCharger kit I didn't hear much of the fluttering...only until I removed the filter and adjusted the jam nut on the spring adjuster. I suppose I can bring it back to ProCharger OEM settings, but it does leak boost...hence, the upgrade to the Hyperboost, but the fluttering is unbearable. Stay tune for the Vortech Race Valve.

What are you guys trying to do to me, make me a Procharger expert! Thanks for keeping me in the loop as you try new things. Once you have figured them out, I will take my vette to my mod shop/tuner and have them apply your tricks.

Okay...had some time to swap the BOVs; the Vortech Race Valve does NOT emit any fluttering noise, you do get a cool mild WHOOSH sound. I'm sticking with this for now until I test-out the HKS SSQV.
Jeff, you asked the location of the BOV; I took a couple of quick snap shots during the install before the dinner nite out.
IC pipe has to be removed to gain access, 8mm to unloosen the clamps.
I remove the two clamps and hose fitted on the 1.5" pipe that tees off the blower discharge duct.
I attach the 1.5" hose to the valve head (flange & mounting gasket end) of the Vortech BOV, as suggest I kept the spring adjuster fully backed off as supplied, the opening point is set as 16" Hg.
Mount the BOV/hose piece to the blower discharge duct and plug the 5/32" vaccum line to the BOV manifold vaccum port and secure it. To prevent debris entering the BOV discharge end, I mount it downwards facing the ground. Reinstall the IC pipe and clamps. BTW: the blk bar shown is the front sway bar.
Hope this helps...PM me if you have any question.

I'm told by Vortech that adding a filter to the discharge side would lessen the sound effect of the swooosh. I may test-fit a filter on it to see what sound it produces, at the time of purchase Vortech didn't have one in stock and the ProCharger filter is too large.

I was under the impression that you could not use a traditional BOV on a centri car and you needed to stick with a bypass like what procharger uses. The reasons I was given, and it made sense at the time, is the blow off valve is always closed until it sees the vacuum/pressure surge from you lifting under boost. The BPV that comes on the blower is always open under cruise, allowing the blower to more or less freewheel under normal driving (hence the fan like sound the car makes when driving) and then closes once it sees the pressure on the diaphragm through the vacuum hose, allowing the car to build boost. I was told that with a standard BOV, there was always a load on the blower at cruise, causing excessive wear and tear and worse MPG (not that MPG is a concern to many of us at this point 
).
If I was informed wrong, please let me know.

A BOV installs in the same way, but is not open under light vacuum- the BPV is normally open and only closes under boost. These look like they are normally closed? I could have been misinformed, certainly would not be a first for the internet . I was just told that it would put the extra load on the blower at all times, which obviously, it will- but I wonder if it is even enough to case the premature wear they mentioned.. Thanks.
