fastcar Posted December 28, 2011 Share Posted December 28, 2011 (edited) Hi peeps does anyone know what the screw on the back of a HKS Bov is for? Edited December 28, 2011 by Gaz6002 (see edit history) Quote Link to comment Share on other sites More sharing options...
Gaz6002 Posted December 28, 2011 Share Posted December 28, 2011 It's for adjusting the pressure the BOV opens at. Quote Link to comment Share on other sites More sharing options...

fastcar Posted December 28, 2011 Author Share Posted December 28, 2011 Thanks Gaz. Am I right in thinking that if I have increased the boost pressure that I would need to adjust the bov to suit it? Or am I wrong? Thanks Quote Link to comment Share on other sites More sharing options...
Gaz6002 Posted December 28, 2011 Share Posted December 28, 2011 It depends really. A lot of people don't even bother with a BOV, but others have one set precisely to try and minimise compressor stall. There are two very different view-points on which way is best, and a lot of the time people actually decide what to do depending on whatever sound they prefer I've also heard of cars running no BOV blowing holes in intercoolers and blowing pipes off, but never seen it myself. There's certainly no exact science you have to implement, but I guess if you set it right you'll be happy it's doing its job. Which HKS one do you have? The Racing SSQV? If so then you can vent off enough pressure to stop compressor stall, but with the normal SSQV I don't believe they flow enough air to totally prevent it anyway. I certainly had a lot in my old single running a normal SSQV at 1.45 BAR. Quote Link to comment Share on other sites More sharing options...
fastcar Posted December 28, 2011 Author Share Posted December 28, 2011 It says on the bov SUPER SQV. I don't really no much about it as it was on the car when got it about 4 years ago. The car was stock when I got it apart from a cat back system. I went BPU about a year ago running 1.2bar so was just wondering if I would be loseing if it wasn't adjusted right Quote Link to comment Share on other sites More sharing options...
Gaz6002 Posted December 28, 2011 Share Posted December 28, 2011 I wouldn't worry in that case mate. You'll be able to tell if it's working properly because you won't get that pigeon noise when you change gear, you'll get a 'tweet' instead.
