garetheves Posted January 4, 2005 Share Posted January 4, 2005 Excuse me if its a stupid question as not very good with engines but what exactly are the differences and advantages of fitting an aftermarket BOV. I have a completely standard 6sp TT apart from De-cat pipes and full exhaust system, oh year and an induction kit. Would an aftermarket BOV make any difference whatsoever and would it be worth buying. Cheers Gaz Quote Link to comment Share on other sites More sharing options...
paul mac Posted January 4, 2005 Share Posted January 4, 2005 absolutely no difference mate, just noise and looks, mines a hks ssqv, sounds great Quote Link to comment Share on other sites More sharing options...
garetheves Posted January 4, 2005 Author Share Posted January 4, 2005 Is it a harsher, sharper sound cos i kinda like the subtle sound of the standard one, different to the harsh hiss you hear on the likes of RS's and the such. Quote Link to comment Share on other sites More sharing options...
paul mac Posted January 4, 2005 Share Posted January 4, 2005 the ssqv is a louder version of the stock bov IMO, its nothing like the cheapo crap you hear on old bangers, Quote Link to comment Share on other sites More sharing options...

SimonB Posted January 4, 2005 Share Posted January 4, 2005 Check out the technical articles - there is an engine components bit in there with photos. Also the technical FAQs have all the info you need about stock vs. aftermarket BOVs. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 4, 2005 Share Posted January 4, 2005 It'll just make an annoying noise, and probably fail quite soon I don't run any form of BOV's on my own turbo engines at all, to be honest. Quote Link to comment Share on other sites More sharing options...
Ian C Posted January 4, 2005 Share Posted January 4, 2005 It'll just make an annoying noise, and probably fail quite soon I don't run any form of BOV's on my own turbo engines at all, to be honest. Do you mean no dump-to-atmo ones, just recirculatory, or none at all?! I know racing cars don't run any sort of valving like this because they consider turbos to be a throwaway component but surely that's going a bit far for a street engine? I've heard turbo stall from a lack of BOV/recirc valve and it sounds nasty.... -Ian Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 4, 2005 Share Posted January 4, 2005 None at all, never had a turbo problem from being run in its efficiency range, but without any form of BOV, nor have I ever found any difference in spool up or anything else apart from noise issues... The car makers only fit them for NVH reasons, the customers don't like the noise of a compressor without any sort of BOV. According to the 2 big name experts I know they feel a lack of BOV makes no difference to turbo longevity. YMMV though.... Quote Link to comment Share on other sites More sharing options...
Jake Posted January 4, 2005 Share Posted January 4, 2005 the ssqv is a louder version of the stock bov IMO, its nothing like the cheapo crap you hear on old bangers, That's right, it's more like the expensive crap you hear on old Supras. Gareth, A loud BOV does nothing for the performance of your car. Their main 'advantage' is that teenage lads think your car is cool. The downside is that everyone else thinks you're an attention seeker whose car sounds like a bus. HTH Quote Link to comment Share on other sites More sharing options...
