supraturbochris Posted October 14, 2009 Share Posted October 14, 2009 hi all. i recently bought a used hks ssqv, i fitted it last night, and to be honest im not really happy. Its not very loud, i think i have fitted it correctly, and tried adjusting the valve on the back but still sounds the same. Is there a correct way for setting these up? Or could it just be a faulty bov? thanks Quote Link to comment Share on other sites More sharing options...
AlanM Posted October 14, 2009 Share Posted October 14, 2009 They are relatively quiet. Which colour of fin is in your one as this makes a slight difference (but not a lot)? Quote Link to comment Share on other sites More sharing options...
SupraAyf Posted October 14, 2009 Share Posted October 14, 2009 The SSQV on my red Supe sounded very loud, but then again, the sound waves did have 9 bonnet vents to escape through. Quote Link to comment Share on other sites More sharing options...
Scott Posted October 14, 2009 Share Posted October 14, 2009 Check youtube to see if the levels are similar to what you are achieving. Quote Link to comment Share on other sites More sharing options...
Jamesy Posted October 14, 2009 Share Posted October 14, 2009 SSQV should be a high pitched loud mate .... Quote Link to comment Share on other sites More sharing options...
Nic Posted October 14, 2009 Share Posted October 14, 2009 Which model is it? The screw on the back adjusts the tension on the spring and when the BOV opens, not the sound. The purple insert (sold separately) is a little bit louder, as will higher boost pressure. http://www.hks-power.co.jp/products/blow_off/option/img/option3.jpg Quote Link to comment Share on other sites More sharing options...
Mcgoo Posted October 14, 2009 Share Posted October 14, 2009 Would I be right in thinking that it would seem quieter on your auto due to the fast, smooth gear change? And on a manual they 'blow off' for longer due to being off boost during the longer gear change? (Waits to be called an idiot and shot down in flames) Quote Link to comment Share on other sites More sharing options...
Jamesy Posted October 14, 2009 Share Posted October 14, 2009 if i want to "hear" my dump valve properly in my auto i get it revving to the point just before it changes gear then lift off the throttle - good for scaring old grannies as you sail past!!

TooColdToDrive Posted October 14, 2009 Share Posted October 14, 2009 Yup, I have a SSQV in my Auto and I have to do what Jamesy said Time letting off the gas with a natural gear change. Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted October 14, 2009 Share Posted October 14, 2009 yer there pretty loud. my sounded loads better once i uprated the boost. the HKS BOV's have 2 valves on them, one for low boost and one for high boost. at full throttle at high revs the high boost valve will open and its not that load and wil be high pitched. and a low gear (in a manual) and full throttle creating aboost build up the larger valve opens and the coolest dump goes of that its fairly loud.....with my car anyway lol Quote Link to comment Share on other sites More sharing options...
supraturbochris Posted October 14, 2009 Author Share Posted October 14, 2009 thanks for all your replies. Its the purple fin nic. Its really weird, if i hold boost on without flooring it, the bov whistles, sounds like its leaking boost pressure or something, maybe wrong. Just sounds like a wet fat Quote Link to comment Share on other sites More sharing options...

Just sounds like a wet fat It will be a silver fin, don't get the fin confused with the purple tip of the piston. Silver whistles, purple wooshes.

TooColdToDrive Posted October 14, 2009 Share Posted October 14, 2009 Any chance of some videos or sound clips I'm running a rev limiter for the break in period, so at best I would make a small noise and some fluttering, otherwise I would Quote Link to comment Share on other sites More sharing options...
