Can someone tell me the difference between roots type and screw type superchargers? I read the screw type uses newer technology and is superior but I dont understand the difference.

1_fast_stang I think brought up the other type I was thinking about centrificle or however the hell its spelled. There are supposed to be two types of different ones. I am sure for the both parts they are the same. I read that whatever type the new Mercedes AMG C32 uses is the superior type of supercharger (or kompressor as Mercedes calls them).

a centrifugal supercahrger is a large round housing(same as turbo)which houses an impellar---large fan basically----
a roots style looks like an intake manifold with it has a couple cork screw looking shafts inside it theat wind up and suck air through it
they both run of pullys
merceds uses roots style
centrifugal are superior
mercedes is full of shit
an centrifugal supercarger will work a roots stle at the track.......(depending on setup and boost of course)

If Mercedes is full of shit then Car&Driver must be too. Here is a cut abd paste from an article in Car & Drivers web site and magazine discussing the light weight and 349hp Mercedes AMG C32 and SLK 32...
Whereas the C43 relied on cubic inches for its grunt the C32 relies on the heavy breathing induced by a belt-driven supercharger. AMG cites the advantages of a more compact engine that allows better weight distribution and because its shorter improved behavior in a crash. The supercharger (a Japanese IHI helical unit rather than the Roots type employed on Mercedes four-cylinder Kompressor engines) only operates when the driver demands acceleration and then at a pressure of up to 14.5 psi. Its seamless operation means youre never aware of its cutting in only of instant power from just a few hundred rpm above idle
and here is the link to the article...
