You're right, I've never even seen a turbocharged car. I once found a JC Whitney catalog in a used bookstore and it had a picture of a turbo kit in it. Way cool.

Maybe. For a little while.

It generally raises the whole curve. It might change the slope, depending upon the turbo used and a couple other things. There probably will be be a slight decrease in the curve, at rpm levels below where the turbo generates any significant boost.

Maybe. It depends on a bunch of things.

I think he built this system the way he did to hide it from view. I suspect he'll do a little drag racing with it and doesn't want his competition to know that he has a turbocharged engine. Good luck with that, I say.
Frankly, I don't see why you'd have anything good to say about this, from a technical point of view, or an ethical one... Your systems shown in the photos had nothing in common with this one, for good reason.
