If one was to run a small vortech like supercharger off one of the pulleys on an x what would be needed for it to work? I was thinking if it is possible to have one end connected to a remote air filter, and the other end connected to the supercharger, so air would be sucked in one end, then blown into the carb (with something fitted to the top of the carb to seal it.) so air would blow through the carb and pressurizing the air fuel mixture. Would this work in theory or am I way off in left field? Any info would be helpful

A far better solution is to run the blower "wet". That is, the supercharger draws its air through the carburator so the fuel air mixture runs through the supercharger.

[FONT=Trebuchet MS, Verdana, Tahoma, Arial]<!-- google_ad_section_start -->It may be as well to outline the different ways/types of supercharging so that anyone new to the subject has a baseline understanding of what's needed.
The term supercharge refers to both belt-driven and exhaust driven forced induction. Supercharge, as a term, is descriptive of the method by which air/fuel AT GREATER THAN STANDARD ATMOSPHERIC PRESSURE is forced into the cylinder of an internal combustion engine.
Supercharging by means of a belt-driven (or, for that matter gear/shaft/chain driven) system is generally used in order to provide full rev-range accessible power increases. That is - step-off horsepower. They are driven, usually, from a belt off the engine pulley. Their demerits are: fuel consumption (they run continuously) noise (they have a distinctive whine from the rotor)and they consume a little power because they are engine driven).
The turbo installation has the benefits of (generally, but not always) cost advantage (there are more of them available for 4 cylinder installations), larger horsepower figures (when set up correctly), lower gas consumption (when running off-boost), low noise (the turbo swallows the exhaust gases). They are driven off waste engine gases.
Their demerits are: Turbo lag (the turbo rotor has to 'spool up' before boost is at maximum, though most modern installations minimize this effect), power transmission can be somewhat sudden (from no-boost to full-boost) causing car control problems at inappropriate times - (especially at high boost levels)such as on wet or icy roads. Finally they create a lot of heat - typically extra insulation of the rotors' housing and extra cooling of the engine bay is required. Lubrication of the expensive rotor bearings also has to be considered. Pre-detonation has to be avoided and power may be optimized by the use of intercoolers - making for a more sophisticated installation (read expense!) - although superchargers too can have intercoolers fitted.
If your preference is for an engine that provides low-end grunt off the line and can give a wide-spec power increase in both torque and power, but not ultimate power, then try checking out a supercharger.
If your preference is for a more middle to top-end rocket with dial-in power boosting then the turbo is likely to satisfy your requirements.
There are other differences but these, I believe, are the most significant.
NOTE WELL: When you increase the horses - don't forget the reins!
Either of the choices for power increases should be allied to a full brake and suspension upgrade in order to safely control your car's new performance. A general rule-of-thumb on costs is to spend the same on your brakes/suspension/steering as you do on the power upgrade!
