HKS ssqv flutter????????

[speed3se-r]

All HKS ssqv past and present owners please respond!

I know this has been beaten to death a million times over, but from everyone who has or has had this "flutter" are you sure air is even venting out? Mine does not. I cannot find any further information other than fluttering is part of the way this unit is supposed to sound...which i still dont think is true.

yea it makes a wierd sound in recirc, ive had the valve for months now without problems. i would have thrown a cell if the air wasnt being vented i believe

 

[speed3se-r]

so you assume air is being vented or are you sure? Fluttering is no joke, and can destroy a turbo. I want to find a cause for this disease. It seems like this HKS product has a high defect ratio. I want to see if there is a relationship between the fluttering at high boost and venting of air. Just to make sure that the people who hear this fluttering are also either getting air vented or not. Trying to draw a connection between that and my ssqv. more info needed....

If your running VTA, I think that sound is actually the design of the fins inside the valve disrupting the air as it vents out. While I could be wrong, I always thought that 99% of the reason people ran the HKS SSQV was the sound it makes over your standard GReddy/TiAl/Apex'i units. Before know, save for the occasional FD, the only real turbo cars I've been in have been Supras, and almost all of them are running the SSQV, and they all made that sort of flutter/turkey gobble noise when venting.

Im confused... Are we talking about Vent to Atoms or Recirc?

 

[speed3se-r]

Either, Or. The fluttering can still be heard when i attached the recirculate tube on, so obviously its my turbo causing the noise. But like mentioned in one of the posts above, a majority of people say that it is supposed to create this "fluttering" noise due to the design. All i am wondering is, IF
, you hear this "fluttering" are you making sure that your blow off valve indeed releases pressure, either into the atmosphere or is recirculated, either way are you POSITIVE that it vents? (mainly at high boost)...that is if you hear this "fluttering".

First off, it does not sound the same from vtoa and recirc. They sound totally different. If they sound the same then there is something definetly wrong...

"fa-fa-fa-fa" is the valve fluttering.
"ga-ga-ga-ga" is the turbo surging because the vent is insufficient.

I know that wasn't very scientific, but it is normal for the SSQBOV to "flutter" somewhat - especially on relatively low-boost applications (under 17 PSI) or part throttle lift.

When the turbo is surging, the flutter is much deeper and sounds like it is reverberating through the entire cold-side air tract.

the valve makes a normal fluttering sound...on recirc you can hear it release the air..


does your turbo do this?

Yep, that sounds exactly like it! Now, what does a "normal" ssqv with the flutter sound like?

its supposed to flutter..it seals itself with boost i think.. im not sure but its something along those lines and thats why it flutters.. unless ur running over 20 psi its gonna flutter...ive had mine on for 3 months now and havent had any issues with it.

yeah, but it doesnt vent at all. There is ZERO air pressure exiting the bov after revving. Only fluttering noises.

 

[clos561]

then you have a problem...mine doesnt do that and it works fine...........no1 has ever complained about hks not working properly...u'd be the first

Run the valve in VTA and rotate it up towards the windshield. With the hood open just rev the engine up. You will see the purple point pull in for the high pitch small relief. If you rev it more the large black diaphram opens and the whole woshing thing happens. If not the valve is hooked up wrong or stuck shut.

 

[knowledge007]

Yeah but wouldn't he be getting a check engine...oh well I suppose not.

Just avoid all of this and get a Forge BPV, direct replacement valve.

 

[hellcat]

Get hard pipes and your flutter will go away. Ask the MSP guys about the turkey sound..lol. Your car will run much better with recirc.

WOW! My HKS doesn NOT sound anything like that, and it doesnt "flutter" its a solid vent. I would be concerned.

 

[Craighjr]

I would imagine no celo. The map is behind the throttle plate so the cars sensors probably don't even know its happening. (maf doesn't read pressure)Mazdaspeeds don't need hard pipes, or there isn't a place to put them really. The Forge valve isn't so great. You have to change springs to get the perfect tension to vent and I understand that for small psi numbers the forge doesn't even open.

Wow that one video sounded like they didn't even have the vacuum line hook up to the BOV. Hope you solve your problem. I've had this but only because i've blown the line before and had to drive for a few miles without a BOV. Sounds cool but you know something is getting messed up...TURBO maybe. Good luck.
