I Designed The B&M Maga Blower and Intake manifold, back in the late 80's. It is a "Roots-Type Blower, but hardly a show piece. Although it was not a Full Race blower, it was used on many drag cars and street cars through out the years. It made 30+ PSI and good HP. It also Won "Best Engineered Product of the Year" @ SEMA in 1990. I Also Built the BBC Motor with the Maga Blower for the Cover of Hot Rod. (upper right) Motor was Engine Dynoed @ Dick Landy's Shop, he was a well known drag racer from back in the day.
Also, you can put any Type of Supercharger or power added you want on a "Z"

You realize that he just completely discredited the entire point of your thread, right OP?

Wow that's amazing man! My neighbor had a Mega Blower on the bbc of his '73 Camaro... I owned a '74 Nova at the time and was always jealous of his gorgeous blower (as wrong as that sounds lol).

went ahead and bolded the important word that your completely ignoring "air compressor" a roots style blower does not compress air the intake is what is technically compressing the air no compression is happening in the blower hence why that style is referred to as a "blower" it would be no different from using a leaf blower to fill a sealed bag its not compressing its moving. the roots blower in absolutely no way supplys pressure it supplys VOLUME. a whipple charger COMPRESSES air between the screws as it moves through the super charger and when the air is delivered to the engine it is already pressurized, a centrifugal supercharger throws high speed air off the compressor wheel through the diffuser which changes it from high speed low pressure air to low speed high pressure air.
seems to me you dont understand basic physics or fluidynamics.

A supercharger is an air compressor used for increasing the pressure, temperature, and density of air supplied to an internal combustion engine.
Lord help me explain this better. Ok here we go if you see the above section of the definition it states that its an "air compressor used for increasing the pressure, temperature, and density of air supplied to an internal combustion engine" This states that it is supplying "air pressure" to the engine. Which is exactly what a roots-style supercharger does. If it did not supply air pressure to the engine it would be useless and just a big shiny toy.

and for bonus points directly from eaton link here http://www.eaton.com/Eaton/ProductsS.../FAQ/index.htm
Q: What’s a Twin-Screw supercharger and how is it different from an Eaton roots type supercharger?
A: All Eaton superchargers use the roots type supercharging principle. The roots supercharger is a positive displacement pump that moves air in pockets from the inlet to the outlet of the supercharger with no internal compression. The supercharger creates “boost” by moving more air into the intake manifold than the engine is utilizing, thus creating higher than atmospheric pressures in the intake manifold. When boost is not desired on an Eaton roots supercharger, the bypass valve allows the supercharger to spin with negligible parasitic loss as there is no internal compression. The Eaton roots supercharger uses 3 lobe (“M”) or 4 lobe (“TVS-R”) meshing rotors that are similar (but reversed) in geometry. The rotors operate at a 1:1 speed ratio.
The Twin-Screw type supercharger is also a positive displacement pump in that it moves a fixed amount of air per revolution. The Twin-Screw uses 2 non-similar screw type rotors that mesh together to compress and move the air pocket axially along the rotors. This internal compression ratio will lead to greater parasitic losses when boost is not required as you cannot turn this compression “off” by simply using a bypass valve. These rotors will have different rates of rotation due to their non-similar geometry and lobe quantity. The rotors of a Twin-Screw will commonly operate at 3:5 and 4:6 speed ratios. This means as the drive rotor spins at 15,000 rpm, the driven rotor will rotate at 25,000 rpm with a ratio of 3:5. This limits the Twin-Screw to lower rpm limits than the roots due to bearing life concerns.

Brandon... 
I actually just learned a ton of new stuff by reading this thread. It's a shame that you started the entire thread in that tone. Instead of sounding intelligent, you came across like a 10 year old.
Take a timeout, try again.

The Stillen Supercharger for the Z is a twin-screw. This is my final post on this thread. Ive got better things to do.
