twin screw is a modified Roots style bolted to the top, and a centrifical is; for lack of a better example; like a turbo with gearing and run by the belt rather than the free exhaust.

The twinscrew provides boost all of the time. The centrifical has to speed up to create boost, so you won't have as much torque off the line. The benefit is that under normal driving conditions, they don't provide much boost, so driveability and gas mileage are better.95 A4 Z28 with 146K miles
