robert_gray Posted August 20, 2006 Share Posted August 20, 2006 Hi guys, Just a quick question, Im just about to purchase a new BOV and not sure on which to go for. Im either going to get the greddy type-rs or the HKS ssqv. Is there a difference between the two as i have no clue? Thanks Quote Link to comment Share on other sites More sharing options...
Lebsteif Posted August 20, 2006 Share Posted August 20, 2006 I like the sound of the greddy RS Quote Link to comment Share on other sites More sharing options...
robert_gray Posted August 20, 2006 Author Share Posted August 20, 2006 I take it thats the one that you have? I was looking on the technical bit of the forum for how to fit one, I dont know if you've done it with your but it showed that when you take to old one off and attach the new one, only the one pipe (and the vacuum pipe of course) is connected and the other is blocked off. Just wondering on why this is Quote Link to comment Share on other sites More sharing options...
MarkTheBoy Posted August 22, 2006 Share Posted August 22, 2006 The pipe you block off is the re-circulating bit of the stock valve. It puts the waste air back into the manifold. The 'Dump valves' don't have this as they vent to atmosphere... making the kkkssshhhh sound that we all know and love. I have the SSQV and I think it sounds fantastic, Really easy to fit (probably similar to most bov tbh) and it looks great under the bonnet. Put a massive grin on my face the first time I pumped the throttle :d Quote Link to comment Share on other sites More sharing options...
hadyn Posted August 22, 2006 Share Posted August 22, 2006 Everyones got a HKS SSQV. They are good valves. However the Greddy does make a good sound. The noise was sampled and used on all the cars in the original fast and furious film/chav fest Quote Link to comment Share on other sites More sharing options...
V8 Killer Posted August 23, 2006 Share Posted August 23, 2006 The HKS is a technically superior BOV and I always recommend it over the Greddy. The Greddy is your typical "spring" BOV. That means the more pressure you put on the spring, the more likely it is to open (leak). Although I have not tested the RS yet, I can tell you we have had many Type S (the BOV before the RS) leak on us and our customers. The HKS is a "pull-relief" type BOV. This means the more pressure you put on it, the tighter it seals shut. Never heard of one leaking. We do offer both BOV's, both universal for those who want to weld on a flange to a hard-pipe and bolt-on for those who want to install their BOV with the ease of a screwdriver. I can tell you from a sales point of view, I sell probably 50 HKS to 1 Greddy. I do sell a good number of Blitz though as well. Hope that helps!

robert_gray Posted September 1, 2006 Author Share Posted September 1, 2006 Cheers, unfortunatly it didnt help as when i posted i was about 10-15 mins away from ordering so i have ended up with the greddy. Just about to go and fit it so we will see what happens. Quote Link to comment Share on other sites More sharing options...
mikeyb10supra Posted September 1, 2006 Share Posted September 1, 2006 I would say the HKS or blitz, they are superior to the Greddy which works as a piston type valve and can fail Quote Link to comment Share on other sites More sharing options...
wkdtime Posted September 1, 2006 Share Posted September 1, 2006 Build quality i'd have to go for the SSQV as its less likely to leak due its design, but for sound i would defo have to go with the Greddy. HKS sounds like a budgie (spell check). Quote Link to comment Share on other sites More sharing options...

Ah poor thing you may be able to return it or cancel it and get the HKS:innocent: Quote Link to comment Share on other sites More sharing options...
V8 Killer Posted September 1, 2006 Share Posted September 1, 2006 I use the Blitz on my car, have for 7 years. Love the sound and the quality. Never had a single issue on them, I run 2. For design HKS is the best. For quality I like both HKS and Blitz. I don't like a whistling sound myself, thus I chose the Blitz.

V8 Killer Posted September 1, 2006 Share Posted September 1, 2006 Why two? Any of the standard size BOV's (in other words anything other than an HKS Racing BOV) can only blow off the air that you see at about 500wrhp. Any single turbo making over 500rwhp should run 2 BOV's. I'm considering a 3rd one at this point. Regards, Dusty Quote Link to comment Share on other sites More sharing options...

wkdtime Posted September 1, 2006 Share Posted September 1, 2006 Why two? I still prefer to run one on single Turbos and a bit of turbo stall:D Quote Link to comment Share on other sites More sharing options...

Tourniquet Posted September 2, 2006 Share Posted September 2, 2006 Got an HKS replica from E-bay for £17 couple months ago and it's the nuts. Louder than proper kits and the only hassel with it was getting a cer-clip to fit coz the one supplied didn't fit. Tig welded it to the hard pipe and blocked of stock pipework and away it went. Tis universal though (meaning don't fit fuck all). Quote Link to comment Share on other sites More sharing options...
