What do you like better, Apples or Oranges? In theory. Turbos are more effecent because they use waste gas to spin the turbo apposed to the parasitic loss of the belt drive on a SC. Let the debate begin.
I've had turbo, but not SC setups. I've researched SC setups & the things that kept me away from SC are:
-You have to change the pulley to change the boost.
-You don't have to get special exhaust manifolds/rework the exhaust for a SC.
-You do have to get turbo manifolds or turn your manifolds around to hook up to the exhaust side of the turbo.
-You can easily increase/decrease the boost with a boost controller.
-A lot more sizing options. With some research you can find the perfect turbo to match up with the displacement of your motor & your power goals.
there is no correct answer to this question.im pretty sure thats why u didnt get many responses. no right or wrong answer. i have a centrif. supercharger but im a big fan turbos depends what u plan on doing with the car. i like my setup because the car runs and drives perfectly normal, makes no boost, puts no strain on the motor 90 percent of the time driving around when your not into the throttle and just running off vaccum and not into boost. then you put youre foot into it and watch the boost gauge climb as you get planted into your seat. and good kits whether turbo or blower are both expensive
