green_dragon Posted June 26, 2004 Share Posted June 26, 2004 As I am new to this forum I don't know if this has been asked before so please bear with me. I have just fitted a HKS Super Sequential BOV to my J-Spec TT, but it does'nt make the fluttering noise I thought it was supposed to. Do I need to change more parts, (induction kit, exhaust etc.) or is the valve not right? I have tried altering the bolt on the back, but it does not make any difference. Any thoughts ??

paul mac Posted June 26, 2004 Share Posted June 26, 2004 dont fully understand what your meaning by fluttering, mine makes the big pssst (technical term) noise at full throttle let off (mines an auto) and a sort of chattering or fluttering noise at medium boost say no more than about 0.4 bar boost let off, oh and welcome to the wonderfull world of supra ownership Link to comment Share on other sites More sharing options...
Spardz Posted June 27, 2004 Share Posted June 27, 2004 Mine was very squeaky at first, much mroe of a chirp than a sound you would normally associate with a BOV, over time this changes due to what i would think is the valve being less stiff. Also sounds better at higher boost lvl dumps. Link to comment Share on other sites More sharing options...
