S430 engine whine making it sound supercharged when it’s not

Is this how it’s supposed to sound? It sounds supercharged when I turn it on and rev or accelerate. Even when the engine is warm.

Check the power steering fluid.

Take the serpentine belt off and see what it sounds like. You can run the engine with the belt off for three or four minutes with no problem.
