Alright, finally got a video for you with my phone. Managed to get the whine recorded. Sorry about the focus; it just didn't want to focus, but you can get a general idea of the speed despite the blurriness. It does this whine thing between 55-63 or so when you are 'light' on the throttle or decelerating. It really isn't bad and whenever I ask my passengers if they "hear that", they never know what I'm talking about, so it is very easily drowned out. I personally like the sound!
It doesn't whine like that when you are a little heavier on the throttle nor does it do it at any speed above 65 that I've noticed. This is the only range I've noticed that whine on. I've had it up to about 120 on the track and never noticed it there either, though my exhaust and intake might have drowned it out.
