Rob_Mitchell Posted August 23, 2011 Share Posted August 23, 2011 Looking into what bov's are available but i have a few questions, some of the questions i think i know what the answers will be but better safe than sorry. 1) Can they be put anywhere on the intercooler pipework? 2) Is 1 enough for my build? 3) is there a certain size i need? Are there any recommended BOV'S which sound good. many thanks Rob Quote Link to comment Share on other sites More sharing options...
Noz Posted August 23, 2011 Share Posted August 23, 2011 Youtube is the best place to find the right sounding BOV for you. I know that some people specify turbo's with internal wastegates due to liking that particular sound instead of BOV's. The position of the BOV on piping shouldn't matter, as long as it's not on a different location e.g. between different components. Piping will have the same pressure throughout, though maybe not the same temperature the general working pressure should be the same. BOV's are rated to different PSI's, you can get higher rated PSI bov's. Rather than having 2, you would be best to try and find one for a high PSI rating I think, as the pressure wouldn't be released equally, assuming your build will require a higher than normal PSI as you specific the possibility of requiring more than one.

Gaz6002 Posted August 23, 2011 Share Posted August 23, 2011 If I were building again I'd be using the HKS Racing one. It copes with much higher pressure than most others out there and also has the advantage that it can be recirculated so you don't get any rubbish 'tweeting' noise Quote Link to comment Share on other sites More sharing options...
Rob_Mitchell Posted August 23, 2011 Author Share Posted August 23, 2011 thanks guys. not really sure what bov is suitable, what sort of PSI's should i be looking at? Quote Link to comment Share on other sites More sharing options...
Gaz6002 Posted August 23, 2011 Share Posted August 23, 2011 What sort of PSI will you be running? Quote Link to comment Share on other sites More sharing options...
Noz Posted August 23, 2011 Share Posted August 23, 2011 What sort of PSI will you be running? now thats the clearest answer to a question i think ive ever seen on the forum!!! Quote Link to comment Share on other sites More sharing options...
Rob_Mitchell Posted August 23, 2011 Author Share Posted August 23, 2011 What sort of PSI will you be running? yeah i understand that but i have no idea lol, what ever ryan and srd do it at? Quote Link to comment Share on other sites More sharing options...
hodge Posted August 23, 2011 Share Posted August 23, 2011 I've got 2 x 50mm turbosmart Raceport BOVs fitted. I've only got 1/2 bar of boost at the min but when they go off there loud as feck. And they look awesome too. I would recommend them to anyone. Quote Link to comment Share on other sites More sharing options...

Noz Posted August 23, 2011 Share Posted August 23, 2011 how come your running 2x hodge? do you find any performance related improvement? Quote Link to comment Share on other sites More sharing options...
Guigsy Posted August 23, 2011 Share Posted August 23, 2011 I've got a hks racing and it doesn't squeak. And gives a nice woosh noise. also get a bitif compressor stall so best of both worlds noise wise Quote Link to comment Share on other sites More sharing options...
Gaz6002 Posted August 23, 2011 Share Posted August 23, 2011 OK let's try this another way - my SSQV couldn't really cope with the pressure in my system when I was at 1.4 bar. I've seen the Racing one cope with loads though... HKS states it should handle 3 bar. If I were you I'd be going with that one as I doubt Ryan will be mapping it quite that high. Not sure how it sounds, but to me that's totally irrelevant You can also use several if you want to, but I can't for the life of me work out why you'd want to.

Rob_Mitchell Posted August 23, 2011 Author Share Posted August 23, 2011 cheers gaz i just didnt know how they are rated thats all mate, thanks. Quote Link to comment Share on other sites More sharing options...
hodge Posted August 23, 2011 Share Posted August 23, 2011 how come your running 2x hodge? do you find any performance related improvement? The build up of boost pressure from a large turbo like mine I wanted a good amount of pressure release so I thought 2 would be ideal. It can't hurt that's for sure.

Scott Posted August 23, 2011 Share Posted August 23, 2011 I read of a guy in the states running an ssqv at 32psi. The way they work should mean they can hold the pressure no bother but I doubt they would flow anywhere near enough at that level to stop compressor stall. The hks racing can flow up to 800hp worth apparently. Quote Link to comment Share on other sites More sharing options...
David P Posted August 23, 2011 Share Posted August 23, 2011 You can also use several if you want to, but I can't for the life of me work out why you'd want to. Twin-tone BOV's maybe. Quote Link to comment Share on other sites More sharing options...
JamieP Posted August 23, 2011 Share Posted August 23, 2011 Go with HKS racing, they open so much quicker than anything else out there, turbosmart are junc imo, so slow to open. Quote Link to comment Share on other sites More sharing options...
mellonman Posted August 23, 2011 Share Posted August 23, 2011 i have a apexi bov its easily adjusted to what ever psi you want, i have it set that with light boost and i lift off you just about can hear compressor stall, but its sound is just old school ,no fancy tweets Quote Link to comment Share on other sites More sharing options...
Rob_Mitchell Posted August 23, 2011 Author Share Posted August 23, 2011 ok ill have a search around at the hks range see whats about. Im up for hearing recommendations on these as i dont want to blow money and obviously want to make the correct choice for my build Quote Link to comment Share on other sites More sharing options...
Rob_Mitchell Posted August 23, 2011 Author Share Posted August 23, 2011 been looking at the turbosmart range quickly, the dual one is good for 200-600bhp, seems a nice bit of kit http://www.turbosmartonline.com/index.php?id=48 Quote Link to comment Share on other sites More sharing options...
hodge Posted August 23, 2011 Share Posted August 23, 2011 Don't think they look as good as the raceport version. Quote Link to comment Share on other sites More sharing options...
Rob_Mitchell Posted August 23, 2011 Author Share Posted August 23, 2011 Don't think they look as good as the raceport version. its states on the website the raceport is for drag and race cars, LIKE 1500BHP applications. Quote Link to comment Share on other sites More sharing options...
hodge Posted August 23, 2011 Share Posted August 23, 2011 How many cars do you know of with 1500hp. Just as a matter of preference really though but I love mine, both of them :-) Quote Link to comment Share on other sites More sharing options...

The race port is the one i had problems with, like tial its very slow to open and i kept blowing boost pipes off, Changed to HKS racing BOV and never blown a pipe off since, they open instantly.
