Answer 2

A turbocharger, or turbo, is an air compressor used for forced-induction of an internal combustion engine. Like a supercharger, the purpose of a turbocharger is to increase the mass of air entering the engine to create more power. However, a turbocharger differs in that the compressor is powered by a turbine driven by the engine's own exhaust gases. The compressor can be powered mechanically by a belt, gear, shaft, or chain connected to the engine's crankshaft.  

Answer 3

A turbo charger uses a fan powered by the exhaust gases of the engine.  The downside is that it requires a lot of velocity from the gases to produce any extra boost, so you won't notice the boost until around 3,000 rpms in most cars.  The other downside is that because the exhaust is pushing the fan it backs up the flow of exhaust and strips you of your power at lower rpms.  That means that you actually go slower when you're in traffic, or a low speed zone.  The only good thing about a turbo charger is that the exhaust velocity amplifies with speed so it can create a much larger boost than a supercharger.

A supercharger on the otherhand produces boost throughout the entire rpm.  You'll feel a supercharger the second you touch the pedal.  It is powered the same way your alternator is powered, by a belt that is connected to the crankshaft.  The downside to this is that it is limited in the amount of maximum boost gain because it can only spin as fast as the crankshaft.

If you want some massive acceleration get a supercharger, if you want to lost your license on the highway going 150 MPH, get a turbo charger.

Answer 4

A turbo charger is driven by the force of exhaust gases.  A super charger can receive power from many ways but most commonly is from a belt driven by the engine itself.  Aside from that both systems work the same they use turbines to force compressed air into the engine in order to create increased capacity for air and fuel in each cylinder.  Increased capacity equals increased expansion which equals increased power.

Here is a great site that provides a very complete explanation.

Answer 5

A turbo charger runs by exhaust gases turning an impeller, which in turn, turns an impeller that sucks air from the intake and forces it under pressure into the intake manifold or carburator. A super charger is an impeller usually driven by a fan belt that sucks air from the intake and forces it under pressure down the carb or intake.

A turbo charger requires a charge air cooler to cool the air before it gets to the intake manifold or carb a super charger does not.

Answer 6

Both compress the air going into the cylinder. More air/fuel volume in the cylinder = more power. Turbos use the power of the exhaust gases to drive the compressor, superchargers take their power direct from the engine. As a result turbos don't work well at low revs (hence 'turbo lag') but are more fuel efficient than superchargers, especially at higher revs. For this reason some high performance cars have both.... a supercharger for low rev power which then cuts out as the revs get high enough for the turbo to take over.
