jackso11 Posted October 4, 2010 Share Posted October 4, 2010 there are black HKS dump valves on ebay for £200 and the same one with HKS labels, box etc for £30. Obviously the cheap one is a fake, but is there actually any difference? or is it £170 down the drain if I bought a real HKS one. Quote Link to comment Share on other sites More sharing options...
JakeG Posted October 4, 2010 Share Posted October 4, 2010 My mate fitted one to his mr2 turbo with no problems mate, but I still think there is always a risk with ebay Quote Link to comment Share on other sites More sharing options...
Gaz6002 Posted October 4, 2010 Share Posted October 4, 2010 I wouldn't buy anything knowing its fake, let alone something designed to deal with high pressure. Quote Link to comment Share on other sites More sharing options...

clapyohandz Posted October 4, 2010 Share Posted October 4, 2010 My buddy had a fake one and it lasted a few hundred miles ; then just exploded. I wouldn't buy one tbh Quote Link to comment Share on other sites More sharing options...
jackso11 Posted October 4, 2010 Author Share Posted October 4, 2010 Why did you ask then? I still wouldn't. I asked what the difference actually is, so someone with one might answer If they explode though, not so good. Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted October 4, 2010 Share Posted October 4, 2010 The difference will be inferior quality parts and workmanship Quote Link to comment Share on other sites More sharing options...
rob wild Posted October 4, 2010 Share Posted October 4, 2010 Years ago now I bought a Sard R2D2 BOV off ebay (not a fake item) and it was fine even on my single turbo. From memory it was only 65 quid! So its really not worth going down the lines of a fake! Quote Link to comment Share on other sites More sharing options...
Lude Posted October 4, 2010 Share Posted October 4, 2010 you can get real seconf hand ones for under 100 quid, id go for that Quote Link to comment Share on other sites More sharing options...
Multics Posted October 4, 2010 Share Posted October 4, 2010 you can get real seconf hand ones for under 100 quid, id go for that The problem with second hand items is that you don't know if they're genuine or not. Fakes are difficult to spot even new... Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted October 5, 2010 Share Posted October 5, 2010 (edited) theres a big different between the 2. The genuine HKS one works on 2 different internal valves making that distinctive woosh that they do. They work Sequentialy on different boost levels as its a pull type piston hence why there called the Super Sequential Blowoff Valve. The ebay ones are 99% plastic and have 1 valve so they sound nothing like them. There is also an adjuster screw at the back and the thread goes after 1 turn. They are utter rubbish!! I know coz i bought for mess abouts a few years back... Chances are if it has HKS logos on it, it will be geniune though...

jackso11 Posted October 5, 2010 Author Share Posted October 5, 2010 see look at this one... http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=250691200703&_trksid=p2761.l1259 I emailed him and asked if it was a replica, I told him I was looking for a replica one to mess about with and he came back and said unfortunatly this one is genuine. It looks real, but a fake can look just as good. But the price?! how can it be genuine for that money? It states it is SSQV and has two valves. Who thinks it is real?

Have a look here, they're copied the latest SQV III. As you can see there's no screw in the back etc etc. It's boxed and everything looks genuine to the unsuspecting customer. It's from a supplier in China advertising on Alibaba, there's 10's of them.... http://www.alibaba.com/product-gs/341753434/HKS_Auto_Blow_Off_Valve_G3.html Quote Link to comment Share on other sites More sharing options...
jackso11 Posted October 5, 2010 Author Share Posted October 5, 2010 If a boost valve blows, its not a major problem is it? I mean obviously it will need to be replaced and the car won't run correctly until it is, but if the boost valve goes can it cause damage to anything else i.e. large cost?

rob wild Posted October 5, 2010 Share Posted October 5, 2010 In a word yes Its the blowing which is the problem tbh. Quite often with the cheaper made ones the piston inside is not machined for tight clearance, and allowing it to leak. Therefore with a boost leak it will be loosing power! Also you may find that it doesn't open until the higher boost ranges which will cause compressor surge! If I was you i'd either keep the stock one which there is nothing wrong with! or save up for a well made one Trust me I know from bitter experience that if you buy cheap you buy twice! or even three times! Its never worth skimping on the products that you fit to the car or who fits them! Surely you could find a good second user product that is within your budget?

jackso11 Posted October 5, 2010 Author Share Posted October 5, 2010 yeah I don't doubt I can find one second hand somewhere, just wondered if it was worth getting a shiney new one and risking it being fake. Quote Link to comment Share on other sites More sharing options...
