i have 99 mustang

Both could work. It all depends on what you need.

I would say a turbo is almost on/off and a centrifugal supercharger is more linear, you feel the boost coming.

Please contact this guy:

He does custom turbo kit if you select this way otherwise, you need to join the turbo forum
