Yes! The valve will not open without vacuum. It's the opposite of a standard BOV where boost keeps it open and vacuum closes it. The SSQV is a pull type, boost holds it shut, vacuum opens it.

What? This is the most retarded quote I have read from any of your comment, so far. "It's the opposite of a standard BOV where boost keeps it open and vacuum closes it" Stop giving out false information

False information? I think you need to learn what the hell you are talking about before you jump to saying someone is wrong. This is straight from http://www.hksusa.com:

"The HKS Super Sequential Blow-Off Valve (SSQV) is a dual stage pull-type relief valve. Unlike typical push type blow-off valves, the SSQV will not leak under any level of boost because the boost pressure in chamber "C" keeps the valve closed against its seat (Diagram 1). The SSQV releases excess boost when there is a pressure alteration in chambers "A & B", not by the rate of boost pressure or vacuum in the line. This ensures a quick valve response and complete closure during idle. Many competitors use a push-type blow-off valve design with a large valve to accommodate high boost / high horsepower applications."

The vacuum line creates the difference in pressure that the BOV needs to open.

Since I can tell by youtr incredibly retarded post that you have the reading comprehension of a 5 year old maybe a picture will suit your primitive mind better? Here:



I'm going to make the best effort to explain this in layman's terms for you. Throttle on boost holds the valve shut. Throttle off boost created by the turbo that is in the piping is vented because the vacuum now creates a pressure difference that activates the relief. Which is what my original post says. Everytime I assume NICO members are smart enough to figure out the details from a few specific facts it comes back to bite me in the as$. Do us all a favor and keep your mouth shut until you know what you are talking about. You were quick to call misinformation but I never noticed where you provided the correct info. That to me says you don't know the right answer, so how in the hell would you know what the wrong answer is?

Dude, redtop...ur the man. I understood what you said from the get go, because I read some more and took your advice and did some more research. Some people 'think' they know, but in reality they just 'think they know'. Which leads me to believe that people should not always believe what they think.

Sorry for diverting off of the main question. It seems my posts draw all the haters.

I didn't disagree on SSQV works on vaccum, didn't you read what I said. and here is what you quoted "It's the opposite of a standard BOV where boost keeps it open and vacuum closes it" Now just think about your qoute, I think what you are thinking of is here is a CBV or compressor bypass valve not BOV

and when I quoted I didn't include the first part "The valve will not open without vaccum" because I know that is true. I also didn't include the last part "The SSWV is a pull type, boost holds it shut, vacuum opens it" because I also know that holds true.

Sighs. Now I have to type every little detail out nowadays.... Everytime I leave detail out it comes back in the form of some nitpicker. It's annoying. I've thoroughly explained the SSQV properly.
