Loud Sucking Noise With Loss Of Power

[tommygun]

G'day I was wondering if anyone would be able to point me in the right direction, recently my car when taking off from the lights etc a large sucking/high pitched sound emits as i speed up (no it's not the pod filter), could this be a boost leak of some sort? As mentioned I have lost power

Couldn't hurt to check hoses/piping anyway.

If it's a standard turbo with the nylon compressor wheel (cant recall what R34 has) and sounds like a police siren it could be a bent shaft in the turbo. This causes a weird noise, probably by rubbing on the inside of the compressor. Happened to my friends R33 GTST a few years ago. Made zero boost after this happened.

Definitely check hoses though.

I once blew off a vacuum nipple I had put in intercooler piping, there was a high pitch sound and loss of power so possibly check for a hole in intercooler/piping?

Vacuum leak, exhaust leak or damaged turbo.

99% it would be one of them but I would be leaning towards to vacuum leak.

Does the car hunt on idle (RPM goes up and down)?

you blowin lots of black smoke? if so cooler pipe/clamp may have come off/be loose

[its me]

yeah as was previously stated, check all your piping and silcon boots for holes/tears, especially if its close to body work

How annoying that somebody would choose the same name as me except add a space in between.. =( But yeh check piping..

easiest way to check if its a vacumm leak is to spray some aerostart or similar around the pipes while the engine is running and if theres a vacuum leak the engine will rev a bit. Dont spray stupid amounts around just spray a little bit. if it revs when you spray some, then check the spot around where you sprayed

Just for info it ended up being my cooler pipe clamp was loose, retorqued it and the problem went away!
