whining.

Wat is that whining noise my car makes when accelerating hard? Sounds like a mini supercharger to me which I think sounds cool. Is it all mustangs? Or fords that do it? I have 2012 rangers at my work and if you punch them they make the same whine except quieter????

Could be a belt. Or even your rear end needs to be rebuilt, it's pretty common.

That or your radio can be transferring tach noise through. If you have a aftermarket radio it happens ALOT. They just didn't put very decent grounds in.

Could be the intake sucking in air or if you have a aftermarket throttle body it could swirl the air making it do that.

Yeah, i wouldn't worry about it too much then. I you feel a loss of power or a rough idle or something i'd look into it.
