Intake Whistle...
Hello all, I'm glad to be a new member!!! I got a good ? for my 1st post...Alright all of my fellow techs, I have a ?/problem! I always have had a little whistle from my 02'Z06 when I'm pulling within certain RPM's. At first, I thought nothing of it until I put on my Vortex Intake yesterday...At 2000-2800 RPM's if I flutter the pedel to acceleratew it whistles, loudly!!! It literally at times sounds like a Turbo spooling up or a SC. If someone tells me it's normal great!, If not, is anyone aware of this or have a fix??? Thanks in advance...

Re: Intake Whistle... (agentf1)
Its normal... If you really want to hear it check out the video of my car running with a Zip-tied airbox. The video is shot from in front of the car, and the whistling is almost louder than the exhaust...
There are two versions I made, a lo-res 600K, and a high-res 9.2meg
Please right click on the link, and do a save as. Don't stream the video, as you will blow my allocation at my ISP right out of the water. Thanks.
lo-res http://users3.ev1.net/~black_ops/vid...1%20lo-res.mpg
hi-res http://users3.ev1.net/~black_ops/vid...1%20hi-res.mpg
Its due to resonance in the intake. I think you can have GM replace the intake, but I decided to just let mine be...

Re: Intake Whistle... (slong)
Whistle is normal....I also had a small whistle with my blackwing but when I installed the vortex....holy cow it does sound like a turbo. At least we know the vortex is doing its job...gobs and gobs of air.

Re: Intake Whistle... (2002 Z06)
Well, the good news is that it seems to be normal...I was told that a possible replacement of the intake may help??? (Intake Resonance Recall) I sometimes love it, but I find myself hating it when I am crusing in 4th gear and it just keeps on whistling. I AM glad it is working and I am going to be putting on a new ported throttle body and LS1 Edit this week as well, so I'll keep you up to date on the results... :chevy

Re: Intake Whistle... (Green Goblin)
I never had a whistle until i installed the vararam vr1b. I haerd that its normal but is amplified through the intake. Mine is only at a certain throttle position which is with the pedal slightly pressed.

Re: Intake Whistle... (rwd)
Some people think its a turbo or a blower . Unfortunatly there is no power gain. A real turbo or blower vette must get alot of attention , my whistle turns heads. My dad says it whistles because it does'nt know the words.
