Over the years I have owned various cars and been involved on different forums and this debate always comes up. I have owned both turbo'd and s/c cars. On the dyno the turbo wins but for a street driven car I prefer a s/c. Turbos are great if your driving style is foot to the floor. For normal street driving a s/c will give boost instantly and even when you are just easing into the throttle from a dead stop. A s/c gives very linear boost. A s/c feels like you just have a much larger engine while a turbo feels weak until you get on the gas. To get the best of both worlds, I have seen people add a turbo to a super charged engine.
