Centri FI: Essentially a belt-driven turbo. Tends to spool slightly faster than a turbo of similar size, but with the drawback of constant draw on the belts that increases with RPM. Boost is gradual though the RPM range.
Roots FI: Typical Muscle-car SC setup. PD design produces large low end torque gains and insane throttle response but tends to have a limitation on the top end. Typically very easy to install, but requires an aftermarket hood. Boost is consistant thoughtout RPM
Twin screw FI: Similar to a Roots style, but with greater top-end potential due to the design. Boost is consistant thoughtout RPM
Turbo system: Superior to SC systems in mounting versatility and effeciency thought extremely challanging and expensive to install by comparison. many up-front turbo system make working in the engine bay much more difficult than a typical SC setup.

I'll add a little further destingtion on the roots versus screw type. The roots is a blower, it blows like a fan would it does not compress. The screw type is a compressor much like the aptly named compressor stage of turbo charger. It compresses the air by first enclosing it and then reducing the size of the chamber it is contained in. Most larger industrial compressors use a screw style compressor driven by a variable speed motor.
The centrifugal uses a turbo compressor with a gear drive to attain the speeds necessary to allow the compressor to rotate at the speeds needed to be effective. This is probably one of the most popular designs for the DIY guy. Mounts off the engine and is belt driven. Can't get much simpler.

I had a Vortech centrifugal once before. On my current ride, I was curious to try turbos. I'm really happy with the results and would do it over again. I like dial a boost, and don't have to mess with belts and pulleys.

Good info, thanks
