Why does my car make a whistling noise when accelerating?

Whistling noises that occur when accelerating a vehicle are often due to vacuum leaks under the hood.

An automobile relies on constant vacuum pressure to operate correctly, according to 2CarPros.com.

Why does my Turbo whistle all of a sudden?

However, if the whistling sound gets louder, more noticeable, or changes in any way, it could be symptomatic of a number of different problems, that all warrant further investigation.
