WW, there's nothing free about a turbo, plant your foot, wait for exhaust gas pressure to build up, the turbine spins under pressure, forced
induction begins...wheeeee!
But there's no cost until you spin the turbine, and then you are not taking power from the engine.
Superchargers take their power from the crank, so you add load to the engine before you even go anywhere. And unlike a turbo, you have to manually
disengage the thing. And, boy, can they be thirsty...However, pushrods prefer a blower over a turbo, over-head cams like turbos more than
blowers...and combat aircraft tend to prefer blowers because you don't want that second or so of lag before you get kicked in the pants.
And then Whittle and Ohayn come along and some Yank invents reheat and pilots are back to lag, but only the time it takes to "push the button,
max".
On the subject of ramjets...didn't the vehicle you pictured have RATO to get it to speed?
