I have also heard the turbine like noise. I was thinking it was the air going through the individual throttle bodies, opposed to one large throttle body. My Dad even said, that thing sounds like its got a jet engine in it when I pulled it up the first time.

Either way a PPI would show any problems. If you can post what the noise is I'd be interested in finding out.
