Bourkey Posted November 18, 2007 Share Posted November 18, 2007 Hi guys and gals!!I know that this may spark a bit of debate but as some you may know im doing the 4EFTE conversion with !Rush! (Alex). I need peoples opinions/advice on dump valves. I have been looking at the HKS SSQV one. Is this a good one?Im not too fussed about the dump noise, although it would be nice, but im after the one that works the best, eg doesn't leak.Thanks in advanceBourkey Quote Link to post Share on other sites
joe-ep91 Posted November 18, 2007 Share Posted November 18, 2007 I wouldn't overly worry about leakages unless your expecting to up the boost pressure as mine only runs 9-10 psi on high boost. Most people that run fmic look to get the blitz ss or hks ssqv. I only got the forve twin piston bov, because it sounds good and was quite cheap.Hope this helps.Joe.

Idrees Posted November 18, 2007 Share Posted November 18, 2007 Blitz or HKS all the way imo! Quote Link to post Share on other sites
Bourkey Posted November 18, 2007 Author Share Posted November 18, 2007 I will be going for more power/boost in the future and yes i will be running a FMIC as i have no vent in the bonnet being an N/A one. I also like the look of the HKS one. I just don't want to have to get another one in the future because it can't handle the boost.ps. Im pretty new to turbos so if im going wrong someone point me in the right direction.ThanksBourkey Quote Link to post Share on other sites
Sparky Posted November 18, 2007 Share Posted November 18, 2007 Greddy Type S There is a link somewhere of all the different ones look on youtubeor block the standard one off and just have the sexual chatter Quote Link to post Share on other sites
paul w Posted November 18, 2007 Share Posted November 18, 2007 Any dumpvalve will do the job. Bailey,Forge,HKS,Blitz,Sard etc the only real difference is the price and sound. Bailey=£50ish HKS=£200 give or take a tenner,new prices by the way. Quote Link to post Share on other sites
Mart Posted November 19, 2007 Share Posted November 19, 2007 Ask Dub-Seven, He tried nearly all the BOV's at some stage... He'd be the right man to ask this... Quote Link to post Share on other sites
Bourkey Posted November 20, 2007 Author Share Posted November 20, 2007 I've just beeen watching some vids on youtube and i like the squeaky discrete sound of the HKS SSQV so i might go for that one unless someone tells me it isn't that good. Quote Link to post Share on other sites
Marc Posted November 20, 2007 Share Posted November 20, 2007 I've just beeen watching some vids on youtube and i like the squeaky discrete sound of the HKS SSQV so i might go for that one unless someone tells me it isn't that good.Get a Blitz Supersound, loud as hell and mean looking. Can get them for £120ish from ebay. look for JPS trade i think it is. Quote Link to post Share on other sites
SiCaln Posted November 20, 2007 Share Posted November 20, 2007 tried the new and old style Blitz dumpvalve, wouldn't have anything else Quote Link to post Share on other sites
stup86 Posted November 20, 2007 Share Posted November 20, 2007 I've got the Sard R2D2. Can't really say much other than it's does its job. Quote Link to post Share on other sites
montanajr Posted November 20, 2007 Share Posted November 20, 2007 Dont have one? Then youll get the lovely compressor stall sound which i love Quote Link to post Share on other sites
NightSpirit Posted November 20, 2007 Share Posted November 20, 2007 On my old engine...I run no BOV at all at stock boost, on the new engine, I run no BOV at all on a TD05 running 1.4bar...compressor stall makes me sex wee. Sexiness Quote Link to post Share on other sites
SiCaln Posted November 20, 2007 Share Posted November 20, 2007 rather smart sound i must say Quote Link to post Share on other sites
StarletRick Posted November 20, 2007 Share Posted November 20, 2007 ct9 compressor stall sounds GAY though. like, really really gay. it sounds good on the right size turbo. and as for BOV. the HKS one is good, but it will annoy the fuck out of you after a few weeks. blitz one is a little more bearable.

NightSpirit Posted November 20, 2007 Share Posted November 20, 2007 That video....is on the CT9, running stock boost. But running through a Blitz filter mounted in the front bumper.I'd say HKS SSQV is best for quality, plus it's adjustable so you can get some stall at lower boost and only 'dump' at higher pressures (several DV allow this)...I'd say my favourite in the world though, if I had to have one is the SARD racing valve...like the R2D2 only not crap.

StarletRick Posted November 20, 2007 Share Posted November 20, 2007 when talking about the big names (hks, blitz, sard, greddy, etc) quality isnt an issue. they will all be above and beyond what youll need from them. it all boils down to sound preference. and i still think the ct9 sounds gay when it stalls.

Bourkey Posted November 21, 2007 Author Share Posted November 21, 2007 We have decided now. Im getting the HKS SSQV and Alex is getting the Blitz SS. We have different tastes in sounds.By the way what is this stall you are talking about??? sorry if i sound dumb Quote Link to post Share on other sites
riko666 Posted November 21, 2007 Share Posted November 21, 2007 could I interest you in some very cheap GReddy Type-RS Replicas? Only bought them as I needed something cheap, quick when I thought I was being ripped off of my Authentic GReddy Type-RS (I still think I am) - only looking for £35 delivered, could do if you're looking for something "in the meantime"?The HKS SSQV's are reknowned for being great units with regards to boost sealing, as they utilise a Pull-type mechanism, which means the boost pressure will actually push the valve closed, so it cannot physically leak through. But they do sound like a canary stuck in a blender - they sound horrible. I currently am running sans BOV - sounds kinda cool, but it's far too loud, and people keep looking at me which I don't like, if they're going to look at it me it best be cause of my striking good looks *coughs*. Opted for the GReddy RS as it's one of the few that come with a Recirculating Fitting Quote Link to post Share on other sites

starlet86 Posted November 21, 2007 Share Posted November 21, 2007 I ordered a HKS ssqv couple of days ago and it is yet to arrive! What does the adjustment do? didnt even know it had it. and what is stall in reference to BOV's? Sorry if im being dumb!! Quote Link to post Share on other sites
stup86 Posted November 21, 2007 Share Posted November 21, 2007 Stall is when the pressure air travels backward through the turbo and slows the blades and can result in lag.When using no BOV you'll get a chatter noise which is caused by the blades of the turbo 'chopping' the air as it passes through them. Some like it, others don't.Theres mixed views on what damage it does to the turbo. Quote Link to post Share on other sites
NightSpirit Posted November 21, 2007 Share Posted November 21, 2007 I ordered a HKS ssqv couple of days ago and it is yet to arrive! What does the adjustment do? didnt even know it had it. and what is stall in reference to BOV's? Sorry if im being dumb!! The adjuster (depends on the model of the SSQV, some have no adjuster bolt) is to compress the spring within the bov, this in turn means more or less pressure (depending on making it lose or tight) is needed to open the valve of the SSQV. Tighter will mean that unless on full or high boost the valve won't open, making it lose will have it dumping when very little pressure is detected.A BOV releases the pressure coming back from the closed throttle plate on lift off that's in the system before it hits the turbo...a dump valve vents this pressure/air to the atmosphere creating the sound, in a recirc valve, it performs the same job but the pressure/air isn't dumped to atmosphere it is passed back into the intake system before the turbo. Some cars that run AFM, a system that measures the air taken within the system need a recirc as measured air is lost to atmosphere in the case of a BOV...causing the car to run rich etc etc. Quote Link to post Share on other sites
starlet86 Posted November 21, 2007 Share Posted November 21, 2007 oh rite thanks people! Does the ep82 need recirc or not? Quote Link to post Share on other sites
StarletRick Posted November 21, 2007 Share Posted November 21, 2007 doesnt need one. no. just make sure you block up the hole in the air intake after youre done fitting the new bov. i like the stall myself. 1.8bar with no bov is lushness Quote Link to post Share on other sites
