I would say put it on and try it out, who knows maybe it will surprise you with some crazy cool result probably not.
The reason why i doubt the efficiency of the blower is because the overall design of most superchargers. They have an obvious triangle for an outlet, not what you have (square on a triangle). And the triangle is a certain size in comparison to the rest of the blower.
Make sure the rotors aren't scraping against anything, put it on and try it out. Make sure you have a scan tool and or a boost meter.
