It’s a feature, not a bug 😉 Completely normal!

 

I admire your ability to notice those details when you're at high revs at WOT. In that situation my attention is elsewhere 😮🛂🌳🪦

 

🤣🤣🤣

 

That's a good thing.

 

Yeah, read something about turbo baffles possibly breaking loose and causing that sound . But my car is new and only has 550 miles on the clock . Also I believe the 750s has modified Baffles to fix the previous problem. Likely normal and no power issue as the car is a rocket !!

 

It’s just the extra boost being let out. Turbos make “more” boost than the engine needs so the extra boost is let go through a “waste gate” valve.

All turbo cars hiss at WOT, most companies tune that hiss to a certain tone.
