Thread: ssqv causing compressor surge

I'm having a small problem with my BOV not opening in time causing my car to compressor surge in between shifts. I am running a hks ssqv and if I build full boost it will let out pretty loud surge followed closely by the ssqv whistle. Does anyone know why this is happening? I would like to get it fixed asap, I imagine this can't be a good thing.

Can you put different springs in it?

Someone told me they use a double diaphram design and you can't swap springs out.

Two things. Can you take a vid of the Surge? Sometimes the SSQV sounds like its surging but its not. When I first installed mine I had it on a weak ass vacuum source and it was actually surging. I then ran a specific vacum line to the BOV and it fixed the problem.

i have one and i dont have it anymore, i recirculated it and wow its quiet

ill try to take a video of the surge after work today. hopefully you're right johnny. the vacuum is on its own dedicated source it should be good.

hopefully you guys can hear it.

whats new? every one i've heard has surged. I dislike that bov.

I'm starting to as well. If I want to get rid of this bov I have to change my IC piping.
