wewsupra Posted November 4, 2011 Share Posted November 4, 2011 I have a bov hks sqv purple fin on my supra twin turbo and in the past with standard exhaust on the car, the bov was not very loud. but last weekend i had a full s/s exhaust put on supra and had one cat removed and now it seems to me that the bov air noise is a lot louder does a bigger s/s exhaust make a bov louder ? or it could be that im just going mad .....

Chris Wilson Posted November 4, 2011 Share Posted November 4, 2011 The reduced back pressure from de catting the exhaust may have raised the boost pressure the BOV is releasing. has the boost gone up? It's not something I experience as I never run any form of BOV on turbo engines. Quote Link to comment Share on other sites More sharing options...
wewsupra Posted November 4, 2011 Author Share Posted November 4, 2011 yeh chris the boost has gone up a bit as well but im real surprised how much louder the bov has gone even at low boost levels p.s chris thanks for that oil leak you sorted sometime ago all is still well ... thanks Quote Link to comment Share on other sites More sharing options...

Supra-duper Posted November 4, 2011 Share Posted November 4, 2011 Same as mine Rich, mine got louder, and when i had the second cat out it got louder still. Have to resist from accelerating and backing off just for the noise Quote Link to comment Share on other sites More sharing options...
