Skunk2 IM whistle

spoonman · Jun 8, 2002

Would a stock 99GSR TB "stock size" on a Skunk2 IM make a weird whistle under %20 throttle and
-190-270mm/Hg vaccum. I'm getting a loud and anoying whistlefrom either the TB or IM. Everything is torqued to spec, new gaskets, but i can't figure out the whistle.

please help...

I had a 93 GS. Bought the skunk2 im as well. Had the same whistle as your talking about. It is not a leak. It is normal. It is from the size of the tb to plenum of the im. Call Skunk2 if you have anymore ?'s.

my friends have skunk2 manifolds and if you use the old stock gasket you get the whistle but if you replace it with a new one you don't get the whistle is what i have noticed

just fired up and test drove my car around the block and between 2,000 to 3,000 rpms (or every time i give it gas)i get a whistling noise. i have a new gasket on TB and IM and everything is that still normal, i have a 94 ls. i emailed skunk2 but no responds yet!

I have the stock IM and a CAI and I get the whistle. Its not that annoying to me, maybe yours is louder?

You cant get rid of the whistle as I know of. everybody that I know that has that IM has the whistle.

all aftermarket intake manifolds (including stock) will whistle on the Integra. It's normal, don't be alarmed.

My friend has a VENOM IM on his teg and his whistle is LOUD and ear-piercing.

Sorry to liven up an old post but I just installed my Skunk 2 intake and I have this same whistle!! Does anyone know if you put an aftermarket TB or a larger TB with this intake, will the whistle decrease or disappear??

what did you use as a TB gasket?

nicklk · Oct 8, 2003

I used the stock gasket, it was perfectly intact on the throttle body

I used oem gsr TB gasket and I get the whistle. But I know that is normal. stefan525

well the mating surfaces don't align on a 60 mm bore TB and the 64mm plenum port bore surfaces and it's hard to get the TB to seal up in most cases. If you are losing vacuum there,then you may want to try what I did: used liquid gasket and wiped off the excess inside the TB once the TB was bolted on.

The flange gasket, EVAP, fuel injectors-fuel rail, PCV valve are other whistling vacuum loss sources. I'd just go through each of those one by one systematically and eliminate the suspects as the cause. Make sure you use Honda's torque down specs and check the hose connections.

Not this again.

The whistle is coming from the TB plate. I've found this using a automotive stethiscope that you can buy at any Pep Boys. Also, the whistle is louder the cleaner your TB is, not much though.

I thought a lager TB might get rid of this. IT DIDN'T. I went from a GSR to a ITR TB.

Maybe it'll go away when i get TB,manifold, and headwork done this winter. Probably not though.

Some people say if you use a short ram you don't get the whistle. Can't say from first hand experience though.

I don't have any whistling with my Skunk2 IM. You shouldn't have one. Trust me, use the liquid gasket.

I have the Skunk2IM as well and I don't have a whistle...It did at one point, but I fixed by ajusting the screw in that's on the manifold..You all should have that adjustable screw.

there is no adjustable screw young fella...

96_GSR · Oct 8, 2003

Well let me look again, and I'll tell you all where the screw was that fixed it.

MichaelDelaney · Oct 8, 2003

you go right ahead and do that...perhaps you should've done that at the start instead of guessing?

spoonman · Oct 8, 2003

Adjusting the screw on the THROTTLE BODYhelps a little, but didnt solve mine.

Learn to ignore this embarrasing whistle, and when people ask... Reply with different but interesting lies.

"Oh that's the sound of an empty nitrous bottle."
"It's just my super charger."
"What whistle, I don't hear anything."
