I was going out to eat earlier tonight and to get there I get to go across 'the bridge'. It is basically a huge smooth flat straightaway. Need I say more?

Anyways, at 145mph there it made no sound like I expected (this was not top speed btw). But on the way back, at around 140 I hear this whistling noise coming from where the hood meets the windshield. It couldn't have been an alarm, since it got louder as I went faster and went away when I came out of hyperdrive. I think it might have been the antenna? It has me stumped.

I'll do it again sometime later this week to see if it does it again, plus it shifted into 5th gear at a 135mph and 5Krpms....so I wanna see what it can really do. Also, is this even safe on the stock PZero tires? something tells me its not

 

Someone slip a turbocharger in there when you weren't lookin?

I get a subtle whistle when I put the pedal to the metal. It's lower pitched at first then gets higher as I accelerate. No clue what it is, but if the AC unit makes a clicky sound, and still works- I'm sure my engine can whistle every once in a while, too.

 

I get something similar...its more of a whine than a whistle. The pitch changes the faster I go
