Turbocharged vs Supercharged...what'* the difference?
Is there a difference between these two or are they just synonyms? I did a search to see if this question came up before and didn't find nothing. :?:

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

And don't confuse a centrifugal supercharger with a turbocharger, they look the same but the centerfrugal supercharger is belt-driven.

A CSC and a Turbo are probably the best to show the differences, roots blowers typically have the most off idle power, but loose steam due to heat. Typically called blowers too..
CSC'* have a turbo-like powerband, but still have the parasitic losses of the supercharger.

Turbo = teh ultimate IMO, tunability for any engine with compressor sizing, boost controllers can do wonders, and they're more efficient then superchargers. If done correctly they deliver power in the entire RPM range too..
The whoosh is undeniable as well.

I've always been a fan of superchargers, myself, even before my first */c car purchase. Turbo lag annoys me, and very few people ever get the turbo-sizing right. They either go large for power and neglect off-idle performance, or go smaller to spool quickly, and lose upper-end. Then there'* the complicated tuning neccessary for turbos to make reliable power.
Give me a straight-forward system. I like being able to just smash the pedal down and bust off the line any old time. I don't have to worry about hitting the power band when I downshift, because the power band is the entire operating range of the motor. If I give up some mileage for it, oh well.
