What does "Blown" mean?
Get ur minds outta the gutter....
Really, what does this mean?
I'm assuming that it's a device that hooks up near the air intake, belt driven, and crams lots of air into the engine for better combustion?

I knew a Lewinski joke would find it's way into this thread 
"Blown" refers to forced induction....ie....supercharged or turbocharged. As opposed to normally aspirated or naturally aspirated engines. Hence the term "Blower" is often used to refer to a supercharger.

Yes it crams lots of air into the combustion chamber, but it does not make for "better" combustion - just more of it. If anything, the quality of the combustion event goes down which is partly why supercharged engines use so much fuel. Still, whatever is lost in efficiency is overcome by the massive increase in airflow - and airflow is the key to power regardless of how you get it.

too much excitement for him, he has heart trouble now...your (car) engine is definitely gonna do the same if it is not blown carefully ('is' means 'is', 'blown' same but different)

With a "Roots" type supercharger, you'll often hear the the term "twin screw". That means the two impellers inside the blower case, and has nothing to do with twins. :o
