Odd whine under high torque

[racechampion24]

My boxster, aside from the other issues I have posted, is making an inconsistent whine under torque. Like in my previous post, I captured it on video and uploaded to YouTube for sharing but this site automods it out of existence. So, the whine is like ahhhwhhwhhwhwhwhwh ka ka ka whahahah ka kak then it goes to a normal porsche revving sound. Once I figure out how to share a link you will have a better idea of what it sounds like and perhaps helped me source the cause?

Thank you!
