HKS SSQV BPV/BOV owners please chime in!!

Definately let us know how it goes. I'm interested in this valve too.

Question for you though: You said PG sells the bolt-on-ready kit. Which is it ready for: vent to atm? or recirc?

Supposedly, the kit comes to set it up VTA and/or recirculation...


first in recirc mode with my COBB SRI ( SRI= short ram air intake for those newbs out there ) you can only hear the BOV at WOT shifts mostly.

Thats disappointing... I was hopping to hear the flutter through my CAI during low boost and the full sound during full boost. I was told it is much louder than stock even in recirculation...

(bump) for AutoX'ers (or anyones for that matter) impressions on the HKS...have you had a chance to install it yet??(cricket)
 
Do any owners of the HKS SSQV have audio in the recirculation setup?

Search pumpkin! No harm I just had this clip laying around.

Impression on the HKS what? Maybe you should search too. There is plenty of info on it but I don't know what your asking for to help out with my experiance.

More specifically: the HKS SSQV version 2 (as apposed to the manually adjustable discontinued version 1) set up to recirc. From what I've found, some people experienced "jerkiness" at low RPM shifts.

I'm anxiously awaiting AutoXRacer's opinions after this install because 1.) He said he would report back, and 2.) He gives honest, unbiased opinions on his mod experiences. :)
 
Man, that video is disappointing...sounds stock. (sad)

The vendor has disappointed me again with shipping... I did not receive my HKS yesterday as promised... :(

Hopefully, I'll see it some time next week... (bang)

I will definitely report back as soon as I get it!! (2thumbs)
 
Yeah if someone had a forge sound clip last year when I bought that, well I would not have bought it. I love the VTA HKS sound so I may just tune for that and screw recirc.

You da man!!

Yea, that clip sounded stock-like, however I'm not specifically looking for the best sounding bpv anyways, otherwise I'd probably go with the forge for a unique sound or a hybrid to get a louder sound. I'm interested in the self adjusting design (no manual tuning of springs/shims required) and how well it works with our cars being that its basically a universal valve with the proper fitting attached.

And also if there is a noticable performance increase (holding boost better after adding an intake/tbe/ic) than the stock bpv. I don't have a boost gauge or any tool to read any ecu data, so in the meantime I'm relying on others testimonials, and AutoXRacer has a very similar set-up to how my car will soon be set-up.
 
I hear you guys...and totally agree, function > form/bling...
But I was really hoping for a slightly louder flutter sound. Oh well...

I'll see if I can data log some stuff with the stock valve and then repeat it with the HKS... Maybe that will have some insight...?

sounds like a plan stan, then we'll know if the stocker leaking myth is true. To be honest i dont want one yet just incase it does hold higher boost, i have no intention of dealing with boost cut until i have a tuning solution in my possession. On the other hand, if your log proves it to hold pressure equal to the stocker then I just wont get one.

EDIT- I'm not in it for the noise
 
I have a question for all you SSQV owners...

I bought the cheaper, not put together version, and now, I'm about to throw it through a wall. What is the trick with the snap ring? I think I'm about to loose it if I don't get this thing put together.

45 degree snap ring pliers that are the right size. If you just get it started press down hard as hell and use a flat head screwdriver to push it in. The spring tension will help it work into the groove. Make sure your putting the snap ring in rounded side up there as well. You can try to assamble it off the car then bolt it up and gently twist it into place. The closest spot to line it up is to have the one mounting nut just above the discharge side when pointing to the right I think.

Thats why I got the bolt-on one.... (first)
 
OK, so finally FedEx delivered my SSQV this morning and I slapped it on before the FedEx guy drove away... (lol2)

I bought the expensive one that simply bolts-on. I did not have to buy any other parts, hoses, clips, or adaptors...

I simply removed the stocker, rotated the bypass hose that attaches to the turbo inlet/intake interface so that it matches up to the HKS and then used the supplied hose and adapter to attach the vacuum hose. Oh, I also had to configure the SSQV to recirculation. The instructions come for VTA...I wish... :)

Oh BTW, I took pictures, I will post them up tonight...

Anyway, fit and finish is A+!!! Easy to install!!!! And 1,000 times better than the stocker...the stocker is really flimsy.

So, what everyone is waiting for...the test drive.

Initial impression is that its quieter than stock!!! (sad)
If you boost anything less than 5 PSI, you won't hear a thing. Between 5-8 PSI and you can clearly hear the flutter. Higher than 8-15 PSI its quieter than stock, I guess that has to do with the valve closing a lot quicker than the stocker. At this point I was a little disappointed...

Engine performance is improved!!! I can't say its amazing, but definitely helps. With the stocker, I held at 15.6 PSI and spiked around 16-17 PSI at 50* degree weather, 30* degree weather occasionally spiked at 19, rarely 20 PSI. Todays temps were 79*-80* degrees. I was piking 20 consistently and held boost at 16.6; got an extra 1 PSI. Now, the biggest advantage I found was that the power between shifting!!! With the stocker, the shifts were smooth and progressive...it eased into boost. Now, as soon as you shift and let go of the clutch and floor it, it threw my head back!!!!

Seems like the engine is very responsive between shifts...I know it has something to do with boost... Maybe the valve closes a lot quicker thus recovering boost quicker...? (huh)

I can't say its worth $275 for its performance gains. It does make a difference, but I would recommend this mod after you've done the basics; intake, DP, TMIC or FMIC, CBE, etc... I think this should be one of your last power mods...unless you have a really bad leaky stocker BPV.

I like it and I'm happy with it. (2thumbs) I wish we could run it VTA though...
I'll post the pics tonight...

glad you got the valve finally it took forever for our supplier to ship them. we just ordered a big stock of them again so we will have them in our hands now.

And as for the VTA we have something in the works we are going to be testing with Driver311 soon so watch for that...
 
Way to go AutoX!

But I can't comprehend why the loudness of the sound that the air makes upon release would be quieter than stock. Since it is holding another psi, I would think that the sound would be a hair louder since more air is being released. I could understand if the duration of the sound is shorter, which would make me believe that the valve opens and closes more responsively, but then that leads me to believe that the sound should be louder! My thoughts are on an endless loop! Must be the way the air is being routed out. Either way, I'd rather have more power than noise, otherwise I could just put a hole thru my stock muffler :).

As far as the increased hp response between shifts, I'm not sure how long a typical bypass valve stays open, but perhaps when you were hitting the next gear with the stocker, the valve was still closing slightly and leaking some initial boost? Don't know if thats possible. Maybe you shift faster than the speed of sound! Thanks for the write-up! Post them pics!
 
I am mixed on the sound...it seems to be quieter than stock at times and others not... Its weird, because the stocker made the same sound regardless of PSI (relatively)... The HKS, changes loudness depending on PSI...
