the basic function of both is to deliver air in internal combustion process the main distinction between the two superchargers are mechanically powered often by connection to engine crick shaft while turbos are powered by exhaust gas
How superchargers work?

https://amzn.to/4b0dhR1
The supercharger sit on top of air intake manifold certain time belt transfer crack shaft power to supercharger pulley pulley diameter and construction is easily accessible way to quickly alter super charger performance characteristics and give your drive system deliver incoming power system to imposing rotors the outside air enter into airlifter and intake pipe the interlocking rotors force air through the supercharger the long fins or ridges that expand the length of router shaft or lobes the air exit the supercharger through a specially shaped discharged put at bottom of housing
Common supercharger types :
1 Roots
it’s basic function is as a air blower as post other designed that compress air
2 Twin screw
it’s featured with common complex routers with internally designed lobes that compressed air as moved through the unit this increased complexity result in better performance and but also higher manufacturing cost
3 Centrifugal
is have much common with turbo design concept they are still mechanically driven they produce an exponential power curve and after tune to make fore boost engine redline
How turbos charger work ?

turbo connects to engine exhaust system the exhaust manifold may b specially designed for turbo placement and to handle increase heat and pressure the turbo has two separate compartments
1 turbine sections
2 compressor sections
exhaust flows to the turbine sections as a exhaust heat and pressure drive the turbine and exhaust wheel the shield shaft connects the exhaust wheel to the compressor wheel the compressor wheel pulls air into the air filter and intake pipes it specially shaped fins force air through a increasing smaller chambers building compression the air get hot during an intake and compression so most turbo setup have an intercooler between turbo and engine intake to get air back down in ambiance temperature cooler air has much more density serving the goal of forcing more air into the engine the intercooler work something like a radiators plugged air passes through internal tubes as outside air rushing outside by cooling
here are common turbo design
single turbo shown here
where all exhaust flows through a single turbo charger
twin turbo
a setup with two turbo charger
twin scroll turbo
exhaust exit the cylinder in a pose with high pressure section follow by low pressure it separates the cylinder in pairs so the exhaust pulls ways don’t interfere into each. other and continous streams of maximum pressure exhaust reaches the turbine
General comparison
they both have common general term
super charger are powered by mechanically energy e.g by connection to engine crink shaft
while turbo are powered by otherwise wasted heat energy from engine exhaust
Boost characteristics
roots and twin screw charger they have positive displacement means they move at same amount of air for each engine revolution
regardless of rpm this also means they can make boost immediately even at low rpm have a fairly minimal power curve
turbo set up produce exponential power curve
since they are powered by exhaust turbo takes time to build turbine speed in pressure before producing usable boost this delay is called turbo lag
Efficiency
supercharger take power to make power have average setup acquire 40-60horse power
function this does not mean that overall engine efficiency is always sacrifice and some setup increase fuel economy when not driven aggressively
turbo do increase back pressure on the engine they drive power primarily as such they can be very efficient

conclusion
super charger can be less complex less expensive way to increase engine performance they can easily be maintained
they can be ideal in a application acquired predictable boost at all rpm
