Whining noise. cant pinpoint problem

[mijake]

I have a hks 2530 turbo on my r33.

Recently i have started hearing a whining noise very very similar to the stereo whining noise you get when you dont earth your sound system properly.

It sounds like its coming from the cabin very close to the centre console and passenger airbag area.

The noise only comes when you are above 0 on boost (apexi boost gauge). It still hits full boost (1 bar) and holds the boost there so no loss in power.

I tried switching off the headunit to see if it was stereo noise but no. noise still there.

I even tried switching off a/c and fan to see if it was that electrical circuit affecting it but nope.

Please help.. im so stuck and the noise is not very loud at all but its annoying. :confused:

Cheers

I had that, check to see if your GF is sitting in the passenger seat?

Seriously though, I've got a turbo whine sound that seems to be channelled down the left wing into the cabin, by the passenger kick-panel...with the panel off it's VERY loud.

nar checked already....gf was in the boot...

i recently had my bov plumbed back but i dont think that could be the cause but could it?....

Its a blitz bov, had it plumbed back...it looks shit coz it doesnt seem to every close completely therefore boost leaking...maybe thats the problem.

LMAO, ive got the same problm with my car, but my turbs is stock. A friend of mine, who is also a mechanic told me its leaking. Hopefully urs is just a simple inexpensive fix.

May i ask what power your making with what mods with your 2530. Im thinking of going one of these, but am very unsure.

Basically, when I had the plumb back adapter for the BOV made from the mechanic, they reused the original gasket, after a few days it started to leak, so i went to supercheap auto, bought some gasket paper and cut it out to the same shape as the original gasket. Fixed the problem straight away. No more noises.

Make sure all your intake pipes are secure and tight, you might be leaking from any of the joins.

Good lcuk
