Bov - Hks Ssqv "noise" Issue

[Phantom Snail]

Hi guys,

i purchased the new 09 racing hks ssqv bov with the mind set that i would be getting the loud sharp high pitched 'ching' noise ... however this is not so ... all i got was a distinct woschhhh noise ... like a sharp water splash if anything ... not the high pitched 'ching' that the ssqv is known for .. so i purchased the purple fin, put it in ... same noise just a lil louder ... so i purchased the gold fin .. same noise just a lil more sharper ...

At this stage i thought it was the bov itself, so i sold it to a mate and purchased the 08 limited edition black ssqv (same as the silver 08 model just black)

Same story ... its NOT making the sharp high pitched 'ching' ... its making the same sharp water splash

The car is an r34 gtr with an arc twin entry intercooler kit which already eliminates the recirculating pipe on the turbo side. The standard twin bov system has been removed but the standard hard rubber hoses have been retained on the throttle body side of things ... so it goes oem standard big rubber hose from throttle body to oem small hard plastic piping which splits into 2 - one end goes to the hks ssqv and the other end goes to the throttle body side of the intercooler ...

There are no leaks whatsoever, holds 20psi easily no issues ...

Does anyone know why the bov is not making the noise it should be?

Any help is greatly appreciated

did you try changing the fins in the black one you bought?

it could also be to do with the way you have it plumbed in. have you also tried playing with the tension of the spring to see if that changes it?
