Glanza_cl Posted July 19, 2008 Share Posted July 19, 2008 i have just fitted a hks mushroom filter and got rid of the factory air box, but now when i drive nd come onto boost i can hear the turbo spooling up nd then when i change gear or take my foot of the accelerator i get a bov sound but i am still running the standard re-serc, is this because the hks filter is less restrictive or do i have an air leak somewhere- it seems to hold boost still nd my boost gauge shows a steady 0.5 no creeping or dropping etc.does anybody no why? ;) Quote Link to post Share on other sites

Glanza_cl Posted July 19, 2008 Author Share Posted July 19, 2008 a recirc is still a BOV, what you are hearing is the recirc dumping the air into the efi pipe, a noise that the airbox masks when it's fitted ;)so no leaking pipes nd nothing to worry about? Quote Link to post Share on other sites
Idrees Posted July 19, 2008 Share Posted July 19, 2008 so no leaking pipes nd nothing to worry about?No I wouldn't worry about anything mate, just like Dub has said you can hear it just because you have an open filter as opposed to the closed airbox. Quote Link to post Share on other sites
