so what is the real deal about this supercharger? i am very interested in purchasing one. my boyfriend says that he's seen it work. it definatly works (right?). he says that it doesn't give you that much boost but it is still forced induction. according to what i have read on the internet it gives you 5% hp but that is more that an intake or headers would do. all i'm saying is that... i don't have $4000 for my comtech supercharger and until then i'm hoping this will do. i also heard that you can stack them and get twice the air or three times the air if you put two or three. i would greatly appreciate it if you do not email me but i'm will look on here everyday, if you have answers to my questions or more to add.
