What makes this Turbo Whistling Sound? [VID]

At 0:52 - 1:14, while he's idle, you can hear the turbo slowly spooling down as it whistles. Does it a couple of other times in the video. I've heard a lot of Neon SRT-4's around houston sound pretty similar. Just curious to know why/how it makes that sound?

That's the sound of a teeny tiny turbo spooling up near idle. K03 VW's will sound like that as well.

Some turbo cars you can hear the turbo spooling through the exhaust. Evos will do it too with a larger turbo and strait through exhaust
