why do you guy's like a turbo vs a centrif Supcharger?

The reason I like the Turbo over the Supercharger is you can adjust the boost on the fly like stated earlier and in most applications you can leave the hood stock for the sleeper affect.
The installation of the Turbo is more difficult with all the plumbing but I believe after the install it is easier and instant to create more power with the turn of a knob under the dash. On an EFI application change up the tune in less than a few minutes and you are done without scratching up your car and getting dirty changing pulleys and belts. The Turbo guy has already ran 6 more times down the track with increased boost/power before the Supercharger guy has opened his tool box if he even feels like doing it.

When the Turbo guy is done he turns down the knob or changes the program back to where it was, plugs in the Ipod and drives 125 miles home rocking out all the way to Van Halen! haaaa
