whining noise under acceleration

I have an 07 4.6L Screw with ~700 miles.

It makes whining/airy noise coming when I am under acceleration from 1250-1750 RPM. It sounds like something is releasing pressure and it only does this during these RPMS. As far as I can remember it's always done it.

Is this normal?

Thanks in advanced

At various times that my truck has been in the shop, they've given me 2 different 2006 F150's with the 4.6. I noticed this same noise in both of the trucks. I don't know if it's "normal" or not, but it appears to be fairly common.

Whining Noise

My 07 4.6 does the same thing. Sounds like the air intake is making the noise. I was thinking of adding a CAI and maybe that will fix it. I don't think it's hurting anything but it can be a little annoying at times.

You're right, that's the general area where the noise is coming from.

I have the 4.6l, I have the same noise too. I have heard that if you change the belt to a goodyear one, the noise goes away, but I am not sure. The whining does not really bother me, because the whining goes away after your reach 35 mph.

It wouldn't surprise me if it was a belt. Now which belt are you referring to?

The alternator rubber belt. I think there is a diagram pic, once you open your hood you will see it. But I am not sure if changing it to a good aftermarket one will fix the problem.
