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

      That looks good, but I think you're going to need much beefier side skirts now.

      They are daft and there's a reason it never caught on. Steering feel? We don't need no stinking steering feel!

      I gotta pull you up on this. It's driving me crazy. A shutter is something that closes, like over a window or in a cmera. The word you want is shudder. That LSD is clearly f**ked. Take it to a diff shop and get it disassembled and examined by an expert. YOu might have plates welded together or something equally crazy.

      S1 rb25/s14 starting problem

      By GTSBoy · Posted

      Check the Nistune doco. There are a few assumptions being made here that might not be valid. I will list the things that occur to me: Base map. Base map for what? Base map for Z32? Then the cranking pulse width is probably wrong for an RB25. The extra 500cc of capacity might well be enough to prevent it from catching. Base map for RB25? I don't think you can load one of those into a Z32. You have to just make the settings correct for an RB25 in the Z32 base map. That is either K or the TIM to get the pulsewidth right. Loom. You bought a loom for an RB. And you plugged it into a Z32 ECU. Did you make sure that any iwre differences were swapped. From memory, there's at least a couple. And as per the others, I would suggest making sure that the fuel pressure is correct while cranking and that the injectors are actually flowing as expected. They really must come out and go on the bench, unless you do find that you have messed up as per above points. I would also suggest watching in Nistune to make sure that everything is reading correctly. That the correct binary flags are raised at the right time (like the crank signal), that there's no stupid values in K or TIM. That you have not got mismatched firmware for the ECU and/or a wrong image loaded.
