Noises

Hey guys
This time it's a mechanical concern.
When I accelerate, as the rpm's climb, I can hear a whirr with increasing pitch, almost like a turbine spinning up.
And when I let off the gas, I can hear that "turbine" winding down.
Now, it's not the intake because that has a very distinctive sound to it, and it's doesn't have an obvious effect of performance.
Also, when rpm's are at 1900, there's a light metal on metal rattle coming from the engine compartment. It's only momentary as it's passing through 1900, but if I keep it at 1900 it is continuous.
Not sure that that has anything to do with the 1st noise since it's been doing the rattle since I bought her in Dec.

I love coming to this forum 'cuz you guys are obviously knowledgeable on the subject and I appreciate everyone's input.

Thanks!

maybe you camaro has a turbo :grinno:

might be alternator bearings going out.

Any way to check the bearings?

get one of them mechanics steposcope things, or maybe it is one of those ricer turbo noise maker things to make it sonud like you have a turbo

I agree w/ the alternator idea

If not the alternator, maybe a loose torque converter?
