Bread box intake ?
 

Have you ever used one? Know someone ect....

The question will be; What gains were seen?

I assume your talking about a Cartech, Comp, or some of the other box uppers. They kill torque, especially on a N/A setup. They are most popular on cars with forced induction.

I know the theorys, I wanted real world. I can build one for nothing. I think it will be good with the supercharger, when I decide to install it. But I want to put it on now, or soon as it is built.
