hks ssqv is not working

[Dayonaise]

Newb question sorry, I did try to search this site and others but could not get the right answers sohere I'm, my bovine does not actuated at any level of boost i turned it up to 13 Psi and still nothing but i can hear the turkey through my air filter. My vacations at idle is a steady -17 and while driving and releasing the gas it goes to -20 so I'm pretty sure i have enough vac to actuate the valve, i have it plugged into the middle 3/8 nipple on the intake and i have completely dissassembled the bov, the valve moves freely and the diaphram looks fine. The pic is where the hose connects too is this correct or should i be connecting it elsewhere for better vac?
Thanks in advance for the help

I'm confused as to what exactly you are asking, and what exactly I am looking for in the pic. I don't see a bov in the pic. Clarify please.

Your blowoff opens when you let off the throttle when your in boost. And you might want to get the turkey out of your intake pipe it is probably blocking airflow

I think he wants a better vacuum source

Literally laughed when I read this. He's got -17 vacations too. Someone was obviously on their phone.

 

[Diamond Star Werks]

Your not gonna hear anything when your in neutral

 

[Dayonaise]

Lol ok i walked into that one and yes I'm on my phone sorry for the autocorrect, the pic is of where the vac line is hooked up it is right in the middle of the intake, and I'm putting load on the engine and hitting 13 psi.
I Will snap another pic of me pointing to the vac line

Ok this is the vac line that comes from the back of my bov and connects to the intake is this correct? And if so would there be a reason I'm not getting enough vac to operate the bov?

I can't really tell how you have your BOV lines routed. The only line that goes to your BOV should be a manifold pressure line. If you have a manifold pressure line hooked up to your BOV you may want to consider the valve to be malfunctioning. I personally have not used the HKS SSQV, but it could possibly need adjustment.

 

[PrimerPLus]

I think that is your vac source for your fuel pressure regulator.

The hose comes off the bov goes under the cas and into where I'm pointing, also the bov is non adjustible

Primer that pic does not have the same port as mine, i have a nipple just below the T and the I on the word multi and tgats where my bov line is attached also if i unplug it my idle drops so i know there's vac there

 

[PrimerPLus]

Do you know the year that intake manifold is from?

Where is the vac nipple for your Fuel pressure?
Are there any nipples not being used?
The nipple closes to your BOV side should be used for your bOV
the nipple closes to your FPR should be used for your fuel pressure solenoid or afpr.

Take a look at these diagrams. They are for removing vac sources but they show a before and after so you can see how it should be connected.

The 3/8 nipple that is under the C in eci is where i have a line hooked to my valve cover if i pinch it i can hear the little ball move inside, as for fpr i have no idea i believe it attached to the same line as my boost gauge if iam reading those plans right?

ok I found a random pic of a 1990 intake manifold that is exactly the same as mine, please let me know if this makes sense or if i should change where my lines are going thanks

That seems right. I think you are good to go.

So why am I'm not getting enough vac to operate the valve?

 

[Robzone0911]

So why am I'm not getting enough vac to operate the valve?

If it was me I would install a nipple on the charge pipe going into the TB, and run my BOV off that.

What makes you think it's not working? If you're running 13 pounds of boost where's all that air going when you left the gas? I would think you be hearing in some compressor surge

 

[Dayonaise]

I hear nothing from the blow off valve but i can hear the turkey sound from my air intake

 

[007jimmy]

Make sure the line is not pinched or ripped in any way. The vacuum source should be 1 line running from the intake manifold straight to the BOV. Is there a "T" in the line somewhere? The noise from the intake is the air coming back through the turbo because the BOV is not opening/functioning or the vac line to it is damged. I wouldnt keep running it like that as its not good for the turbo compressor wheel.

 

[Dayonaise]

Ill try another piece of hose but no there is no T just a straight line and i figured it was some sort of surge or reverse flow that could damage my turbine wheels that's why i wanted to check with the dsm community to be sure

I put a brand new hose on and it has a bit more vac but at 10 psi its still just a faint turkey flutter i also put my ear right to the opening and raved the motor in neutral it did open a small amount but hardly enough to be considered a bov haha now i know it Will be only 1 or 2 psi in neutral but the sound doesn't seem to change even at 10 to 12 psi wot I'm going to try my brothers bov to see if it my car or the hks but that won't be till the weekend so hopefully i can figure it out before then

 

[kbiker76]

Take it out for a drive and get on it WOT and let off that's when your bov will open not just revving it in neutral doesn't do much

Bad bad idea. Bov needs to be connected after the throttle body. Wastegate is sourced before the throttle body.

The SSQV BOV is super quiet with out the whistle tip. Its probably working fine, you just cant hear it (assuming it doesnt have the whistle tip installed)

This is off topic but, are you running a GM MAF? I cant see it on the pictures you posted.

I have been taking it out thats where iam getting the 10-13 psi from, i can hit 7000 rpm and about 13 psi and still not even a peep just turkey flutter from my intake.

no gm maf yet I am using a 2g maf on a 1g motor i realize i should be using a gm maf with translator but just have not able to pick one up yet. although i did buy a translator from a local guy and it turned out to be for a 1g so i just kept it since i got it cheap.
as for the tip itsw just the basic HKS disk with the small purple cone in the middle, my brother in law has the exact same one and his is very loud and hes only running 8 psi

The SSQV BOV is super quiet with out the whistle tip. Its probably working fine, you just cant hear it (assuming it doesnt have the whistle tip installed)

I have the gold insert in this pic, which is supposed to be the higher sounding pitch of the two, I will do my best to upload a HQ vid of the issue tomorrow morning thanks guys

if you hear a flutter then your bov is probably working. most hks ssq bov dont work to well unless you get a softer spring. I just put one on my car and it does the same thing. its kinda sounds like a KKKSSSS KKKSSSS KSSS KSS... right?

 

[TechTherrien]

I have this same bov on my 92 talon and at 14 psi I would guess about 60db of tone is coming from mine. I will examine mine later cause I'm at work but I will try to get some pix for ya at lunch. Sounds to me that vac source is weak

Nvm. I ran and looked at mine and I am the exact same vac line as you.

 

[Dayonaise]

mine sounds like this but nowhere as loud
