Theres a weird sound during start up, acceleration, and shut down. Its a grinding noise. Once the car warms up theres no sound. Once I shut the car off I hear the grinding again. I'll try to upload a video.

 

how many miles are on the car? engine is noisy in general it sounds like, ours has 110k on it.

that flutter is worrisome, sounds more outbound then the turbo and bigger. almost like a aux fan blade hitting the shroud or something

 

I'd try isolating the location with a mechanic's stethoscope.
