Help! Listen to this noise

[ddac]

Longtime reader, first time poster here!

Looking for help diagnosing the problem causing the whining/screaming/airplane noises in videos. 2008 E90 m3

At my last track day, everyone was so impressed that i put the time and money into supercharging my car.

I didn't. Its stock, minus camber plates, tires, and racing pads.

Clearly its loud as heck outside the car, but i cant hear it inside the car. When popping the hood and revving it, everything sounds normal. Only seems to be obvious when wide open, headed down the front straight. There almost seems to be 2 similar noises simultaneously.

Air leak? Pullies? Brake pad rub? Im so f@^%ing fast my car cant take it???

Thanks for the wisdom in advance. I promise to post results as this unfolds!

Can't view your vid. But if it sounds like this it's a common problem.
