Here was a decent little article by Evan Smith

There will always be a special place in my heart for blowers but for now my Gutter Sucker Turbo will rule EVERYONE!!

I thought you guys were cool now.
Peace brothers. 
Back on topic:
I have one question about the by-pass valves on both units. I know that both the Radix and Screw have a bypass valve that bleeds off air that is not needed at part throttle/cruising conditions. I've also heard the claim that while the by-pass valve is open on the Radix it takes about 0.33hp to turn it (very impressive indeed). My question is: Where is the by-pass valve on the screw units? Unless its somewhere in the housing, while the screws are in the act of compressing, then the air is in fact getting compressed when its not needed too.
The Radix, because its a true "blower" can bleed off the air anywhere in the plenum (or after the rotors). To compete with that, I would think that the screw would have no choice but to bleed it while the screws are compressing. Hmmm....
Along the lines of reliabilty:
I would think that a factory vehicle equipped with a twin screw would be far more reliable than a factory equipped turbo vehicle. I know with the import crowd, factory turbo'd vehicle owners are always having to junk or rebuild the turbo. Yet, OE's constantly put turbos on cars. I guess the efficiency far out wieghs the reliability aspect. Plus the screws are made by Lysholm, and the roots are made by Eaton. As an outsider, I would think the OE's would rather do business with a more established US base company like Eaton. It just makes good business sense.
Oh yeah, another question. I heard that Eaton bought part or all of Lysholm. I heard they own the patent or rights to the twin screw now. Is this true? Will we be seeing twin screw eatons? There's some food for thought.

You need to know the history a little better to understand the comment
It was meant as a poke, not a stab. I am sure he knows that.
