How much boost will a HKS SSQ BOV take? From the research I'v done everyone seems to think very highly of it. I would really love to be able to use one BOV all the way to my goal of 450 hp. SO, is the HKS SSQ BOV up to the task? Would it work with a Injen Intake?
 
i had a hks bov and i got ride of it for the greddy rs bov like it alot better

I did the exact opposite. The greddy type RS is nothing but a piece of crap IMO, search around and you'll see why.

HP has nothing to do with how much a blow off valve can "hold." What you should be asking is about PSI not horsepower.

If your asking about this and an Injen intake (which is overpriced) then the SSQV will hold just fine with whatever you throw at it.

+1 ^^^^

I have used the type rs, and they are cute for the price, but could be better.. My boy's 3kgt vr4 has one, and that bi*** will not stop fluttering.. It sounds like it is weazing.. haha... But I have also seen them work just fine.. soooo.. yeah.. Just read posts about people that use them, and just get their opinion..

SSQV is a very well made piece of equipment.. I recommend it for sure, but dont expect to just put it on (or any BOV for that matter) and just have it work.. You usually have to dial in the adjustment spring for your ride to get it to function correctly.. But its not hard, take it on a few runs, bring a screw driver, and adjust it till it doesnt flutter, and doesnt stick..

TIP: you should ALWAYS have a few screwdrivers and wrenches in your car.. You never know when you are going to get stuck 3 miles from home with something as simple as a hose the blew off the coupler, TB, etc..

Sounds like your buddies RS valve may be adjusted wrong. I've ran both the RS & SSQV & the factory setting on the RS made it flutter on my setup as well. I had to reduce spring pressure to the min. & then it blew off properly all the time.

The current SSQV's no longer have any adjustment on them (unless they've changed that again since the redesign). The SSQV will hold all the boost you can throw at it for your 450hp goal but I'm sure there is a max (I would expect probably around the 50 psi mark, like was mentioned). To be honest I'm not a huge fan of the SSQV when recirculated. It seems to basically flutter all the time unless under WOT/full boost. It works/sounds much better when vented IMO (of course must be running a proper setup to vent)

The new SSQV require NO adjustment what so ever. Another plus for the SSQV.
 
That's dope.. I didnt know that.. One more reason why hks is one of my favorite companies.. Always progressing..

No... Its not adjusted wrong.. Trust me, I have tried adjusting MANY a time.. haha.. It just will not stop fluttering.. I think he may just have a bunk BOV, though..

No adjustment on the hks bov = get that shi+.. :thumb:
 
Thanks for all the info. I have one more question for yall however; Will I be able to just swap the old piece of junk CBV with the HKS one without having to mod it to fit?

I'll assume your refering to the stock BOV as a CBV? & I will also assume you have a stock upper intercooler pipe? If so, no it won't just bolt right on. You'll need to get a SSQV to 2g adapter (not 100% sure but I believe these exist). Otherwise you can get an aftermarket upper IC pipe & have it flanged for a SSQV or you can have it flanged for a 1g valve, which is more univeral as alot of the aftermarket BOV's offer an adapter to convert them to a 1g flange, (good idea if you think you'll be changing valves in the future). Then you just need a SSQV to 1g adapter.
 
If any of you have fluttering, it's most likely coming from the turbo, not the BOV. Get under the hood of your car and rev it. You should hear the fluttering coming from your intake tube, not your BOV. That's your compressor surging. OMG
 
Out of curiosity, why has Tial not been mentioned once in this thread? I have an SSQV and love it, but Tial has legitimate claim to being the best BOV out there for our cars. It used to be that you couldn't recirculate, but now that you can with the new Q line, I see no reason why you shouldn't at least look at them.

i had the hks ssq bov without the flange and i just put the bov on my stock uicp, it wouldn't stay on as much as i want it to. when i hit full boost the bov pops out and car died. a freind of mine running a 97 gst spyder with all rebuilt running 600 whp with the hks ssq bov had no problem with it. i'd recommend getting a new pipe with the hks flange on it.......

Yes the Tial is great but the OP was asking specifically about the HKS. As you said the Tial can't be recirculated until their new Q BOV, but have you seen the size of that thing? From the pics I've seen, it looks huge & with the in/outlet config, most are going to have a hard time trying to ge it under a DSM hood in the typical location.

In this case, no it probably isn't compressor surge. Its extremely common for the HKS SSQV to flutter unless under full load/boost.


To the OP, are you getting the new upper IC pipe flanged for SSQV or are you going to get the 1g flange & run a SSQV to 1g adapter? If you looking for a good adapter dejontool has what your looking for, thats the one I run. Not exactly a cheep adapter (think it was around $45) but it does work great. Having the UICP flanged for the 1g valve has allowed me to run 4 different brands of BOV's without having to change the flange on the UICP.
 
I have had the HKS since 1998...love it. An intake filter kit and that BOV were the first mods I did to my car. It even worked for me vented to atmosphere w/ a stock 2G MAS. There was a bit of bucking after getting back on the throttle, but upgrading the size of the intake snorkel fixed that. Get the SSQV and have your UICP flanged for it. You asked for a BOV that will support you through any mod stage? That's the one. Do it, smile, and don't look back. I STILL run mine to this day...11 years later... :)

The last post before you're was from 18 months ago. I hope he's found a BOV by now. (He's actually running a 1g DSM BOV.)
 
hahahaa. Since somebody brought up Tial. Is it true that Tial are recommended for high psi cars (30+) and NOT recommended on cars with ~15 psi? I already have a tial sitting in my basement and I was planning on properly running it but my FP Green will probably see ~20 psi.
