All great suggestions, thank you.
After driving with the windows open I am not so sure it’s coming from the engine compartment anymore. It could actually be from the right center or right rear. The differential possibility is intriguing. Because it only happens for a few seconds when I accelerate, regardless of the gear. End it starts about half a second or a second after I start pressing on the accelerator. So at that point there is a load on the differential, so that would make sense. The only thing that doesn’t add up is that it is it is such a high-pitched whine, almost more like a whistle. Also, if it was the differential I would hear it coming from both sides. But in this case it’s only on the right side.
