Turbocharging and supercharging grew up in aviation , where there is much more variable air pressure due to altitude. They were more a "hack" to get more envelope out of an engine system. Started seeing them on consumer ground vehicles in the '80s, when everything had to have a "turbo" button because PCs had one. It's never been clear to me that they are really all the great of a fit with terrestrial engines. Part count goes up, heat goes way up in spots and there is of course lag.
