PROBLEM - DC2R whistling noise - sounds like turbo but isnt

[thegame888]

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

[SHI-FTY]

All dc2s do it n its no problem dude

[xntrik]

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.

[GSi_PSi]

lol. dude search another noob had the same problem , been covered

[T-onedc2]

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.

[tOniies]

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

[thegame888]

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?

[SiReal]

yes it should. mine is stock and it does.

stop worrying and enjoy the drive :)

[dsee2]

u've got aftermarket headers on?

[thegame888]

u've got aftermarket headers on?

Nah, they're stock

[Riced_Civic]

its normal dude all after market exposed pods do that.

[SHOGUNOVDDRK]

as others have said, its an itr thing.

Going to clean my throttle body. Went to super cheap and saw these. Which one do you reckon? I don't want to damage anything.

definitely the whistling from air induction

[jetdc2R]

lmao that whistle is normal my type R always done that even with my power getter it whistles

[Lukey]

my dc4 sometimes makes it with stock air intake.

just a thought, have you checked your vacuum hoses? not sure if the car is old enough but its a cheap thing to change them out and almost always ive found whistling comes from them:) if you want you can spend more and make them match the rocker cover:)

if you dont just want to blindly change them, open the engine bay with the engine running and have a listen where its coming from, if you need to just grab the throttle n rev it up a lil (2-3k)... some guys make a wierd listening device with a bit of spare vacuum hose...

The whistling noise means your Vtec is gonna fall off.

serioulsy its normal. usually a lot louder if u do not have an intake box.

[anfo2gig]

yep whistle nosie is normal i got it too :)

[kevster]

im running replacement k&n filter in std airbox its makes a slight whistle , had a hks pod did it a bit more especially wide open throttle before vtec and also your oil catch can (if youve got one) can make a whistle / noise as well

[Vtec R]

the whistle noise is the butterflies in the throttle body this is common for dc2's

[yah mum]

how much boost are u running?

[hisoka]
