The way things work in this universe of ours is strange, there’s lots of evidence that the same, or very similar things are invented in different parts of the world at the same time by people in similar industries. It was like that with cars too, having people working on different types of engines in different countries and having basically no contact. Internet searching hints that after engines had been in production for a while, engineers started trying to increase the power output, and back then with the knowledge at hand, it usually went the way of increasing engine capacity, but this soon proved inefficient and space became a problem. The basic things needed for an engine to work are air, fuel and spark. Adding more air to the fuel creates more power, and so in the early 1900s Swiss born Dr. Alfred Büchi started tinkering with ways to make this happen, and by 1905 he registered the first patent on a turbocharger. Sure it was for a marine application, but an engine is an engine and it clearly migrated from there.
There’s only really been one kind of turbocharger for many years, with the only real addition being the electric variant we’re seeing people trying to make work properly these days. You get different variations in the normal turbocharger design though, which is where things like twin-scroll, variable geometry, and variable twin scroll comes from. These can also be used in combinations, most modern supercars are using a pair of turbochargers. A few automakers even have models that have a supercharger system combined with a turbocharger system, both working together to try and get efficient power. On the supercharger side of things there’s also a few kinds beside the older Roots-type. Twin-screw superchargers are aptly named because they basically feature a pair of rotating screws that create and direct airflow. A more common aftermarket conversion is with the centrifugal supercharger, it can work better in smaller spaces and due to the way they use impellers, they have a housing that’s easily confused with a turbocharger.
