I agree, and, there's also the difference in the torque/hp curves. turbo's will look better for peak power, but average power across teh band, S/C is better IMO - at least...the right kind of S/C. In addition, as far as I understand it, a turbo can drain low-end torque/power until the turbo's spin up. Might not be much of an issue...but if you drive your car with the engine mostly under 3K RPM, and occasionally get above 5K RPM, a supercharger is the better option, IMO.

Actually the correct answer is.......

Depends on the type of SC.
