My 2013 Infiniti G37 Journey 7AT sedan (bone stock besides coils+wheels) makes some very interesting sounds when shifting at high RPMs.

A 370Z flew by me on the road, and of course being the type of driver that I am, I sped up and egged him into a race (in Mexico). After the race, the 370Z asked me about my car and whatnot. I just told him I was just a stock '13 G37 with ~300 horses. He was like, "No way. I think I heard some boost under that hood." I've also noticed this sound as well, but because I had no idea what it was, I just responded to the 370Z driver with "I think it's the intake."

Immediately after a high-RPM shift, you hear a whistling sound, similar to a BOV. I know my car isn't turbo'd and I'm also curious where this sound is coming from. Anyone know?

It's the flux capacitor kicking in.
