Umm.....a Roots blower IS a positive displacement blower.

A turbo is centrifugal (exhaust driven) and there are centrifugal superchargers. (belt driven)

A Roots or positive displacement blower always will make more off idle power than a turbo or centrifugal blower.......in other words, no turbo lag.


Howstuffworks "Supercharger Advantages"


"Roots and twin-screw superchargers, for example, provide more power at lower RPM. Centrifugal superchargers, which become more efficient as the impeller spins faster, provide more power at higher RPM."
