this seems to be a pretty good, quick rundown if anyone wants to know... rather than reitterating what it says, i'll just post a link...

http://en.wikipedia.org/wiki/Supercharger

i love topics like this... learn more and more just by looking for answers to others questions

yeah I like these threads too. These are the ones I learn and don't post on! lol

then how come a roots can not push as much boost as a twin screw or can they?

i'm not sure really, however if a twin screw can push more boost (i dunno), i'd go ahead and imagine its because a twin-screw is more efficient than a roots blower, therefore can create more boost at any certain engine speed?? I just take that from the articles i've read

are they lighter? sorry for the dumb questions, but this really interests me as much as turbos

check out the two links i posted from "how stuff works" and "wikipedia"...

its not so much as they move more air( per diplacment) its how efficently it does it. Twin screw are acctually outlawed in top fuel because of how efficent they are.
