when in gear, usually from 2nd on up, from 2k-4k rpm, and 25% throttle (i have vafc), theres a whisteling noise, and only under all those conditions... its been getting progressively worse... ne help would be appreciated, thanks.

 

hm.. by any chance do you have any type of intake installed on your car?

 

most CAI's make that noise... i noticed it dramatically when i used my GS-R TB on a skunk2 intake manifold...

 

well yea, i got an aem short ram, but it never whistled on my '00 si that had a cai.. if its the intake, then whys it only whistle under those certain conditions?

 

its normal....learn to love that sound

 

its air traveling throuh a tube. when it reaches a certain velocity or frequency, it will whistel. normal to hear it when you have an open filter intake.

 

Tha whistles go WOOOO!!!

Sorry...couldn't resist.

with an intake, that whistling sound is normal.

rotflol!!!! WOOOO WOOOOO

 

It's the air filter. Most AEM CAI's do it, I noticed that my friends Arospeed (chuckle) short ram intake does it the worst on his 96 hb.

Nice theory, but it's actually the turbulant air passing over the butterfly in the throttle body that creates the whistling noice, and it's audible when you have an aftermarket CAI because the stock resonator box is removed which dampens the sound.

 

i personaly love the whistlin sound, of course everytime soeone comes into my car who dont know about any of that stuff there all always like "whats that noise' or, your cars breaking, "or you need new breaks" haha

 

thnx for the replies guys, guess i'll jus leave it be then

 

My 99 GSR with a skunk2 IM and a GSR 60mm TB whisltles. With my ITR TB it whistles even more.

 

I love the whistling sound!
