I would love to see some real world results with a switch like this



I did a magazine article a few years ago where I tested a bunch of intakes on the street as well as the chassis dyno. The Victor intake didn't make anymore top end power in my combo but felt sluggish at the bottom end. I switched back to a Performer RPM which worked the best in my combo.

Every combo is different, in some cars the Victor would be the way to go.
