 Here's an example of the 910S exhaust manifold used on the Emme 422T. Front is to the left, which put the turbo down low, just behind the timing belt/ chassis cross-member. Unfortunately, there were only about 40 of them made.

That's a very compact design, and manifold runners longer than that will result in more turbo lag. I can envision an aircraft using a l-o-n-g system like you described, since they pour the coals to it, get to cruise altitude, set the throttles to cruise power, then never move the throttles again until it's time to come down. Cars operating in traffic change throttle position all the time, and require good response.
