That rattle sounds timing chain related.

I could't hear any grinding noise in the video - it sounds like a regular N14 or N18 engine to me. But those DI engines are so noisy it's hard to tell from that video if anything sounds off.

Just letting everyone know the sound was the forge intake, took it off and never had the problem again. Why it was doing it I dunno?

Hopefully that works -
Also you can notice it goes away towards the end of the video
-
Also oil level is fine.

Checked my turbo turbine it's solid and spins freely, so I guess that eliminates the turbo???

I don't know that I hear a rattle? Not saying you don't hear one just I'm deaf, haha! The only thing that really sounds different to me since I bought it is that weird sound that I've noticed? Anybody else hear a rattle by chance? I'd guess it's possible because I'm not sure what else it could be. The rattle could be the turbo heat shield because ever since I put it back on it rattles once in a while ( I know its it because I can put a screwdriver on it and it stops immediately). Just haven't had the motivation to tear it all apart and figure out how I put it on to make it that way unless its the manifold being shaped different that is causing it. Is it possible to just get an aftermarket heatsheild and remove it entirely and maybe put a turbo wrap if the space around it would be too much after that?
I've checked:
Oil
Coolant level
Turbo Plumbing intake and pressure side
Turbo turbine (feels solid wiggle wise and keeps spinning after you spin it)
Direction of the filter in the intake I bought
I haven't checked:
Belt just doesn't seem like its on that side but will give it a peek tomorrow when the light returns
Pretty much everything else hahaha (because I have no other clue where to check besides internals and if it is I'd have to be headed into the Mini dealer because it's under warranty and I haven't been doggin it that hard but have meesed with the turbo technically and want to make sure I'm not the one who pooched it ya know what I mean?
Thanks so much for responding Nathan and anyone else who might step up to the plate. I appreciate it dudes! -

Hmm, you guys super sure before I make an appointment? Maybe I should make another video where I'm not moving around so much trying to catch the other sound, haha. That really sucks.

Good video/noise of the timing chain noise

That sucking sound does not sound right. Maybe the muffler delete pipe came loose? The performance loss would make sense if a pipe has popped off somewhere -
I made an appointment for next wed, hopefully its nothing that will go catastrophic before then as it's my only car. The muffler delete and all the plumbing of the turbo is tight, put some soapy water around the discharge pipes to see if air was blowing out and there isn't. The engine other than that sucking sound sounds like it always has since mile 9 on the odometer. In the video I literally just started the car with my phone on hoping to catch the noise. In my experience until the motor actually gets going its a little noisy, I mean you can hear in the video it starts to quiet down. I dunno, hopefully it doesn't crap out on me before next week. When I say performance btw im talking about the turbo lagging after shifting, it still pulls as hard as it ever has it just doesn't keep pulling through the gears like it did. There's a lag now with the oem diverter valve back on versus the Forge valve but as I said I heard the flutter and was worried it might be causing turbo surge so I took it off for now until I could get some insight or opinions.

Thanks again guys

If it turns out to be your timing chain tensioner I'll be surprised. I haven't heard of an N18 having issues. -

There's a definite whirring sound in there it's just getting drowned out because of the phone's mic compression, its in the back ground and definitely louder and more noticeable in person. That's the only thing I'm worried about, the chatter is normal or at least it's been that way since it got off the boat and I sat my butt in the drivers seat. Almost sounds like a big old roots supercharger.
