PROBLEM - DC2R whistling noise - sounds like turbo but isnt

**thegame888** · 23-12-2009 05:15 PM

So as some of you may know, recently purchase a dc2r. I drove it back to Melbourne from interstate. On the drive, there was a pronounced whistle coming from the motor at a certain point with acceleration. In fact if i accelerated at the the same rate it would whistle continuously. Then as i went past or below that point in acceleration, it would dissipate and eventually disappear altogether.

So took it for a major service a few days ago. Mechanic isolated it a leak in the pod filter. So we got rid of it, and installed a stock air intake with new oem filter. Now the noise is almost gone, but theres just an ever so slight whistle like before. It sounds like its coming from behind the engine, near the accelerator cable. But its just too hard to be sure. Its hard to hear with the bonnet popped. Its more pronounced when I drive. All the hoses are tight. The intake is fine. Its so irritating.

My mechanic is saying that he can't hear it but thats crap. I definitely can. I think he just doesn't know how to fix it.

Any ideas? Any one can help?

its just the pod sucking in air. aftermarket pod filters are usually louder than oem. hence when u changed to oem, its more quieter

its nothing to be worried about

Dude you;re so paranoid.

It's DC2's trademark. (Not sure if its all DC2/4 but the DC2R definately makes it)
Makes the whistle noise when it sucks in air.

You can get rid of the sound by random intakes (probably ebay)

Anyway; its normal to have the whistle induction sound.

^^x2.

ive put a sri with an exposed pod in my d16y4, it makes this whistling noise at 60% acceleration. nothing to be worried about imo.

My b18c2 has that slight whistle sound, im thinking its from the throttle body.

Yeah nothing to worry about, the type of filter material used affects the sound you get, in my experience a foam type filter (eg; Spoon, Trust, HKS) have a louder whistle.

mmmmmmmmmmmmmmmmm the whistle is the closest thing to a turbo for a P plater like me.

Hmmm, its a stock airbox and filter. I removed the pod just after I purchased it. Stock shouldn't have a short, high pitched whistling noise just after throttle opening from about 2000 rpms should it?
