Alright guys,
With the SC12 supercharger kit, does a dump valve need to be fitted off the backfire valve?
i guess the backfire valve is to release the pressure out of the inlet manifold.

The backfire valve vents to atmosphere only in the event of backfire to release the pressure in the manifold as not to damage the SC.
You can't use a blow off valve because as soon as the throttle is shut there is no boost build up as it is a suck through system.
