Whine noise when I revved car this morning
Anyone know why when I revved my car this morning in park, I heard a whine like from the front end? Sounded like a hellcat whine, but clearly this car isn’t supercharged. Later on in day I revved and it didn’t make that noise, just the loud V8 rumble

Part 2
Definitely related to engine not fully being warm. I just tried it again this morning after letting engine warm a little bit but not fully.

I've seen where a failing bearing for the idler pulley/tensioner for serpentine belts can cause a whining noise. You say it sounds like a supercharger, but I've also heard the sound mimic that of a power steering pump with air in the hydraulic system ( on vehicles so equipped ). The pitch gets higher with RPMs.
