Wiese,

Right now, there is no Twin Screw supercharger kit avaliable, so your question is asking us to choose between 2 non-existant choices.

However, i would like to help you regardless. You say you are new to the car terminology, does this mean you are new to modding cars, new to supercharging, etc?
What is you history with modifying cars.... What kind of cars have you had, what mods have you had done to them, etc.

I would like to know this, and then we can get you going in the right direction, heading towards whatever goals you desire. Send me a PM, so we dont clutter up this ancient thread with irrelevant talk.
