DamanC Posted June 13, 2006 Share Posted June 13, 2006 If you pootle about then you cant hear it. I was in the same situation a few months back, after i fitted it, i said to a mate "ah its a bit chavvy but bugger it" but the responce back was "its not chavvy on a car like that" Also dont forget its funtional Quote Link to comment Share on other sites More sharing options...
SupraAyf Posted June 13, 2006 Share Posted June 13, 2006 So if you spend enough then there won't be a wedding fund; worth considering mate. You can get married any time but your car won't wait!

Feakins Posted June 13, 2006 Share Posted June 13, 2006 Not sure whether I want one either. If you kept the revs below 2k would u not hear any valve noise at all? Quote Link to comment Share on other sites More sharing options...

garetheves Posted June 13, 2006 Share Posted June 13, 2006 in the past ive heard loads cars with a big singles where when the guy lifted off the go faster pedal it made an awesome chatter noise. I was told that this was due to not having a BOV, and the turbo trying to stop spinning against the resistance of the gases. Is this right?? If so i must admit that its a much nicer noise than the hiss of a BOV but i must admit i wouldnt like to replace the turbos every year cos surely the build up of gases must damage them long term.

NO thats the large external wastegates they have, BOV (to atmosphere) have no adverse effect of J spec Cars ( No MAF) and if you are a single with external wastegate then you can still hear the chatter on lift off.

Feakins Posted June 13, 2006 Share Posted June 13, 2006 I take it you can't get a waste gate for a standard j spec? Quote Link to comment Share on other sites More sharing options...

Ahh i see. cheers for clearing that up mate. So not having a BOV, even on a single, wont do damage to a J-spec car?? Quote Link to comment Share on other sites More sharing options...
wkdtime Posted June 13, 2006 Share Posted June 13, 2006 Standard J Spec Tubbies have internal wastegates which are very small and can suffer from over boost when fully decatted, the fact is that its internal and pretty small, to hear the chatter from outside you need a larger external wastegate which comes with a full single kit.

Lol think you mis understood, all turbos need BOV (recircualting) be it UK spec or J spec to prolong the life of the trubo, now the BOV's that go 'Wosh' are vent to atmosphere type and are only suitable for J spec cars as the use a map sensor to measure the air (i.e air after the intake) and UK specs measure air with a MAF (air before the intake), as wosh type BOV dont recirculate air back in to the engine, the MAF on UK specs does not take this account and would still supply X amount of fuel hence it will run rich and can cause stalling problems, The J spec does not suffer from this as the loss air is accounted for and it supplys fuel correctly.

stupra Posted June 13, 2006 Share Posted June 13, 2006 I thought you could get BOV's that were reasonably quiet, without the big hiss. Am i wrong ?. Quote Link to comment Share on other sites More sharing options...
wkdtime Posted June 13, 2006 Share Posted June 13, 2006 Yeah you can, you can get recircualting BOV's for cars with MAF, and even ones which part vent to atmosphere and part recirculate, this does help illiminate the over fueling and stalling problems on MAF based cars, but the problem would still be apparant.

stupra Posted June 13, 2006 Share Posted June 13, 2006 I think you could get away with a loud BOV on a soop anyway, its not like its a chav car, an they serve a purpose. My girlfriend don't like em though, but that wont stop me getting one if i need one in the future. Quote Link to comment Share on other sites More sharing options...
wkdtime Posted June 13, 2006 Share Posted June 13, 2006 Yeah you can aslong as you have a nice meety zorst and some body Mods Quote Link to comment Share on other sites More sharing options...
Gary Posted June 13, 2006 Share Posted June 13, 2006 I have had my HKS SSQV for 2 weeks now and I am really pleased, was worried at first it would sound too loud but the more I hear it the more I love it! At high revs you just get a quick high pitched whistle which sounds great, I also love the sound it makes when you slowly lift off as it starts to whistle, can only describe it as ch-ch-ch-ch. lol Quote Link to comment Share on other sites More sharing options...
stupra Posted June 13, 2006 Share Posted June 13, 2006 Yeah think your right wkdtime,its easier to get away with if the cars got a nice sound, an some body mods, it all clicks together then. Glad the HKS one sounds good Gary, thats probably the one i'll go for. Quote Link to comment Share on other sites More sharing options...
Sandy-m2 Posted June 13, 2006 Share Posted June 13, 2006 How much Quieter does changing the fin in the BOV make it? Quote Link to comment Share on other sites More sharing options...
Gary Posted June 13, 2006 Share Posted June 13, 2006 Stupra, have a listen to the sound clip of the HKS SSQV on the mkivstore website in the support and downloads section, sounds great and this sound clip swung my decision! Quote Link to comment Share on other sites More sharing options...
