A turbo charged engine gets an air boost from a turbine that is spun from the exhaust of the engine.. A supercharger pumps air also but it is driven by a belt that is run off of a crankshaft pulley.. The turbo usually has a little bit of lag because it has to wait for the engine to "spin up" before it is pumping air at it's full capacity.. A supercharger is pretty much instantaneous but the belt takes away a small amount of the power that it makes..

The typical boost provided by either a turbocharger or a supercharger is 6 to 8 pounds per square inch (psi). Since normal atmospheric pressure is 14.7 psi at sea level, you can see that you are getting about 50-percent more air into the engine. Therefore, you would expect to get 50-percent more power. It's not perfectly efficient, though, so you might get a 30-percent to 40-percent improvement instead. The key difference between a turbocharger and a supercharger is its power supply. Something has to supply the power to run the air compressor. In a supercharger, there is a belt that connects directly to the engine. It gets its power the same way that the water pump or alternator does. A turbocharger, on the other hand, gets its power from the exhaust stream. The exhaust runs through a turbine, which in turn spins the compressor (see How Gas Turbine Engines Work for details). There are tradeoffs in both systems. In theory, a turbocharger is more efficient because it is using the "wasted" energy in the exhaust stream for its power source. On the other hand, a turbocharger causes some amount of back pressure in the exhaust system and tends to provide less boost until the engine is running at higher RPMs. Superchargers are easier to install but tend to be more expensive

( a turbocharger is technically a type of supercharger) they are simply a fan that forces air into the engine, and the more air/fuel an engine gets the greater the potential power. Generally a supercharger is assumed to be "mechanically powered" by the actual engine, usually by a belt. A turbo is driven by the force of the exhaust gas leaving the engine. A supercharger normally gives better low speed power, a turbo is more effective at mid to high speeds. The only supercharged cars that come to mind are some Mercedes and Lotus.

They both basically do the same thing: Force more air into the cylinders to provide a better fuel/air mixture.
A Super Charger is belt-driven vane (fan). If you open your hood, you'll see a bunch of black belts. It is hooked up to one of those, and as the belt spins faster, it drives the vane faster, which forces more air into the cylinder.
Some people don't like Super Chargers because while it is being driven by a belt, it also creates more of a load on the belt, causing it to slow down a bit to drive the vane, so you don't have "full" power.
A Turbo charger is a vane being driven by the exhaust of the engine. The exhaust flows past a vane, causing it to spin. The opposite end of that vane is the end that forces air into the cylinder.
Some people don't like Turbo chargers because although it does make use of potential energy (exhaust), it only really begins to work at higher speeds, not right away, like the turbo charger.
Just a little side note: You may have heard of something called an intercooler. All it is, is a radiator for the turbo or super-ed air. The vane is spinning fast, which creates friction, and causes the air to warm up. The colder the air, the more power you'll get from it. So yea, the intercooler just cools that air before it enters the engine.
Easy! :^)

They both do the same thing but HOW they di it is what makes them different a Turbo-charger uses exhaust gases to spin a turbine attached to a shaft which spins a turbine on the other side where the intake air is coming in. This forces air into the engine. A Supercharger does the same thing but instead of being turned by exhaust it is physically hooked up to the engines belt drive system. If you ever hear someone talking about Turbo-Lag they are referring to the non-instantaneous response as it takes the exhaust gasses extra time to "Spin" up the propeller.

A turbo is driven by the exhaust and a supercharger is typically belt driven. A turbo puts less stress on the drive train due to its lag or slow response. A supercharger provides power sooner. And finally, a supercharger driven by the belt takes more power to operate whereas the turbo uses spent gases from the exhaust.

the main difference is the supercharger is mainly belt driven.
but the difference that interested me most is the supercharger gives an awesome 20bhp extra than a turbo charger and believe me this is noticeable

turbo is usually controlled by mechanical components where as supercharged is electrical

trubo lag is a term used by people who use to large of a turbine housing a properly sized turbo will have very little lag

a super charger is belt driven as has been said however its main boost is from low engine revs and tails off at mid to high range...
a turbo is gas driven and comes intop play at high engine revs so they both work at oppostite ends of the scale.......however it is possible to fit both
