What's this noise?

[99RedDragonCamaro]

I hear this noise under the hood that is sort of a whining sound. It only happens when I accelerate. It does get too loud, not annoying or anything, just something I've never heard before from an engine. Keep in mind I've only had this car for three weeks and I noticed the noise right away when I test drove it. I just figured it was something with the air intake. Am I right?

i've got a pretty similar noise but its coming from the belt area. i'll let you know if i can find it

I can hear a noise like that if the radio is off. I have no idea what it is, but mine has been doing it since it was new.

I think i have the exact same noise as you red dragon. sounds like its coming from that area now. let me know if you figure it out.

More than likely it's your belt. My gatorback makes a whining noise when I accelerate and from what I understand that's pretty typical of gatorbacks. Personally I think it sounds kinda neat.

yeah i think all the fbodys have it, i noticed that when i first bought mine. mostly in the 2-3k rpm range for me. sounds similar to a supercharger?

[Jonas]

mine just started recently though, and its like the noise yall are talking about but annoyingly loud

[99RedDragonCamaro]

Well it sounds like this is pretty normal. Thanks for the posts everyone. I agree with marvin and 00firebird it sounds kinda cool. I may go ahead and tighten my belts and see if anything changes. I'll let you all know.

Mine makes that noise too. I thought it was the belt, so I changed it... and it's still there. Guess it's normal...

Next time I ride in my friend's Camaro, I'll listen for it.

I get it too.
Check your Alternator!
Mine's on it's way out. I can tell, because if i'm sitting stationary in traffic, the Voltmeter on the dash dips down into the red.

hmm. On some model cars its probably the throttlebody. On my moms Impala it does the same thing because the throttlebody is actually computer/motor controlled and not a drive-by-wire setup where its a throttlecable connected to the pedal ;) I notice most people who complain are in 99+ cars which I hear are equipped with them.

SWEET! I'm going dragging tomorrow then. :D

Antman. I will check my alternator. It was one of my other first guesses. But my volt meter is just fine. Hardly any movement, but worth a check.

Are there any intake mods that would make this sort of sound? Maybe something has been added to this car that I am unaware of?

Just turn up the radio. :D

[BLLDOGG]

mine does it and i did check my alternator and it was fine. check your just incase but it might just be normal. the noise inside the car when the radio is off, thats normal radio interference.
