The Lotus on the left is supercharged, while the VW has a turbo
A turbocharger uses the heat and coercion of exhaust gases to gift its compressor.
Positive vs. Centrifugal
Both designs are used to aliment pressurized air to an internal combustion engine. Extended air vigour equals more oxygen, and more oxygen makes for a deeper controlling engine.
A supercharger uses a cummerbund, chain or gear connected to the crankshaft to turn its compressor.Though they both exists to push additional air into an engine for increased horsepower, superchargers and turbo-superchargers (as they are properly avowed) force approximately it in two indubitable at variance ways.
HistorySuperchargers were originally developed in 1860 as a mechanical Slogan to provisions coal blast furnaces. Turbochargers were patented in 1905 and basic used in 1920 to elevate the output of diesel freighters and locomotives.
Traditional superchargers are clear-cut displacement designs, allusion that they change the same amount of air for every rotation of their compressor blades. Turbos and modern centrifugal superchargers move less air at low speed per revolution than they do when spinning faster.
As their speed is directly proportionate to engine RPM, superchargers make boost all the time and are best for torque and acceleration. Turbos are used to make high RPM power.
