Stillen Supercharger estimates???

Mike

roots makes low end torque, where a centrifugal is like a turbo and needs to spool up, so it makes its power in the upper rev band.

I've installed and driven both types on 350z, and I preferred my roots to the centrifugal. On my C6, I went with centrifugal, which I preferred over the Callaway roots that I drove at a corvette school. The corvette already has a lot of low end torque though.
