Sort of "vice-versa". The blower/supercharger is driven directly off the motor, hence it is always "on". A turbo charger can be run off of the engine via a pully or off of the pressure created by the exhaust flow. When you give it more gas, it comes on more.

Yup yup! Turbo is more efficient but lots more expensive and confusing.., usually that is. I almost canked my entire engine design last night and started to redesign for a blower but I re-reconsidered after looking at the difficulty of findig aftermarket forged parts. You could build a mild blower engine theoretically with cast equipment and only run like 10psi or less i thought about 4psi would do and DD comes up with 500hp. Not bad but ill wait until i have some spare equipment to burn through.

No you have to get a blower specific carb the kit tells you exactly what to do as far as the entire engine build and everything. The hood well actually its a whole front end for 1100 to 1300 dollars tilt or pull off. http://www.usbody.com/

Turbos are a little more risky. You have to know what your limits with your motor are. What CR to run with what psi, and setting up the waste gate properly. A gate failure could be vital.
Blowers are direct and consistent peak boost.
From what I've seen, turbos are dominant over the blowers with proper setup.
Here's some info on the subject.

While we are on the subject of supercharging, Doug Herbert's catalog shows a BDS programmable electronic fuel injection setup for the top of a roots style blower that uses a bug catcher injector hat, and looks VERY cool. This too, can be yours for between $6500 and $9000.

You see some FEs in magazines and on the internet sometimes with modifications that you just can't buy. It is sometimes amazing what some people can do with a little ingenuity and a whole lotta time and money.
