Supercharger vs. Turbocharger

What is the difference between a Supercharger and Turbocharger. I looked em up on google, and they both seemed to be quite similiar? What is the underlying difference between the two?

I thought you'd know

I could tell you to search for a similiar thread as ive seen a few but im bored

really short definitions(assuming you know what the parts are called etc etc)

turbo- pressure from the engine's exhaust pushes an impellor(thing that spins) lol
which then spins another impellor (directly connected) and the second impellor is the one that the fresh air gets blasted into the engine from, giving you power

-supercharger- sort of like a turbo, but nothing to do with the exhaust.
a belt going from the crank spins around making another pulley spin (the pulley connected to the blades/impellors, making them cram air into the engine , giving you power

now im not sure if I shouldve used the word impellor as much as I did, but hopefully you get the idea

These are the two reasons why car forums of this type are seldom the best place to actually learn something useful... Disinformation and misinformation.

The reason that they seem quite similar is because they are. Superchargers and turbochargers (which are technically called turbo-superchargers) do the same thing. That is to increase airflow into the engine thereby increasing the amount of oxygen which allows you to burn more fuel. The key difference is that turbochargers are driven by exhaust gas flow and superchargers are driven by a belt, chain, gear drive or directly off the crankshaft. Belt drive is the most common on cars.

EDIT: I forgot to add that all turbos are centrufgal but superchargers may be centrufigal or air pumps (Roots and screw type).

A turbocharger comprises a "turbine" in the exhaust air stream for motive power and a mixed flow "impellor" in the supply air stream for pumping and compression. It is a supercharger, but given a different name.

A supercharger is assigned to mechanically driven supply air compressors on engines, most commonly belt driven.

Both of them are "super" because they compact more molecules than found at ambient condition into a given volume of air, not because they are supadupa.

Sorry if i sound stupid but,

1. Where does this hookup on the engine?
2. Do both of them attach in the same location?
3. Does this decrease MPG?
4. Are all turbo-superchargers/turbochargers the same, or do you need customs for each individual engine?
5. Is it "healthy" for the engine to be receiving more air/fuel than it should?

Remember what we spoke about on the subject of research? This is not that. The answer to all of your questions are readily available with with a bit of searching. Will it be effort on your part or spoonfeeding?

1. Turbo on the exhaust side and super somewhere it can get access to a drive belt or gear.
2. Both have their charge air pipes connected to the intake of the engine.
3. Not for the same amount of engine power production:- VE is better.
4. No/yes
5. Ambiguous question

I read up on a lot of stuff. Since i discovered howeverythingworks.com, i've read up on transmissions, horsepower, torque, engines, and now im going to read about how the clutch works tonight.

Some stuff is a bit confusing, and most articles don't answer all of my questions. Hours of searching, when i could come here and have an answer in 10 minutes. I'll be honest im not the smartest guy in the world, sometimes stuff needs to be put in layman's terms for me to understand.
Isn't the forum for questions anyhow? This is why i enjoy coming here atleast.

You didn't discover anything since it's howstuffworks.com not howeverythingworks.com
