I agree that there isn't really much point in this other than to see if you can. Then again, he has a @jak9922 wide arm kit, so it can certainly handle more speed. I think it's more clickbait than anything.
He is/was a member here, and there is a backstory that soured some people on him. I like his videos OK...right up until I had to become a patreon supporter to finish watching one.
My fav is the winter ride he did on the 500. Well done.
He also did a nice video on the takeover a few years back.
I think the turbo with a little boost will be alright. But the head is not designed for any performance (obviously). Power curve will still flatten out on top end, compared to the gain at mid. Small valves. Small lift. Small ports & runners.
