All right all you HKS SSQ owners my bov is making this bubblely flutter sound when I let off at lower rpms (1000 to 3000 rpms).. It sounds pretty gay. Do any of you think that tightening the HKS adjustment screw would make a difference? It didnt do this till just recently. I checked for loose clamps. I found nothing. Anyone with suggestions?

 

BUMP TO THE TOP PLEASE........

 

Just play with the 10mm bolt till it sounds ok to you (turning the bolt in tends to kill some of the flutter at low rpm, low boost but every car seems to sound a little different)
hope this helps

 

yep, tighten it up a bit

 

to me it sounds like your getting surge...looseen it up

Ok now Im confused....... Two responses say tighten. One says loosen. I guess try'em both??? From what Ive found out about compressor surge so far is prior to the bov opening up you hear a metal like sound, I only hear this sound when I'm letting off the throttle. Imagine if you will light throttle release and you hear underwater like bubbles being released. Thats what I'm hearing at light throttle

 

If you are at full boost... and let off the throttle entirely... what sound does it make?

 

A sharp high pitch sound. I guess normal HKS SSQ style.

 

High pitched "woosh" sound? Like it's supposed to?

If so you can tighten the bolt up a bit if you really want. Sounds like you BOV is doing what it is supposed to. HKS SSQ is noisy at atmospheric pressure/the edge of positive pressure.

 

Would a change on the intake filter of the turbo alter the sound as well?

 

No.

 

So tighten the bolt to alter the sound and a find a sufficient vacuum source.

 

BUMP.......ANTOHER QUESTION

 

After visual inspection and hitting the throttle at idle both the primary and secondary valves open if you tap it to like 2000rpm. I Thought the secondary was supposed to open under a heavier load/boost???

 

BUMP TTT.....

 

How about trying to adjust the little 10mm bolt? I mean, all this posting and blah blah blah'ing and you could have walked outside, adjusted it and tried it out.

 

Yeah true.......I felt pretty dumb when I saw that and tried adjusting it. Hey I'm orginally from Boston, Ma. You boosting up there?

 

Sure am, the weather is gettin gnice and I have had the car out a few times, she was sleeping all winter......damn salt!

 

What part of Boston?

 

Watertown Square is pretty close to me.

 

I use to live in dorchester almost a big chunk of my life.
