dumb question

ok so im new to the super and turbochargers but anyways...

what is the difference between the "super"charger and a "turbo"charger?

Both turbochargers and superchargers are called forced induction systems. They compress the air flowing into the engine. The advantage of compressing the air is that it lets the engine stuff more air into a cylinder. More air means that more fuel can be stuffed in, too, so you get more power from each explosion in each cylinder. A turbo/supercharged engine produces more power overall than the same engine without the charging.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.

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.

There are no dumb questions, just dumb answers! lol
A turbo uses exhaust gases to turn a turbine to force more air into the engine. A supercharger uses the drive belt / belts to turn the a turbine to force more air into the engine. I'm sure others will elaborate.

Turbochargers are considerably more efficient but are also more difficult to tune because they are load sensing. That means that throttle application (load) determines how the turbo responds rather than engine rpms. Turbochargers need more attention to installation due to higher operating temps. In terms of cost break down the turbocharger vs. superchargers are really quite even. You pay more for the turbo upfront usually but you wind up spending the same getting a supercharged system to perform on equal terms. My opinion, with quality tuning almost available anywhere with these trucks, I'd go with a turbocharger. I've seen too many blower-to-turbo conversions and their results to go otherwise unless cost and installation we completely out of the question.

wow that was a better lesson than what my chemistry teacher blabed on about today. Thanks for more than clearing things up LOL

so this means you are looking at forced induction?
