Look at the size of a burst panel, compared to 8 throttle blades wide open.........less area. A burst panel usually only helps a light sneeze when trying to crank. For a big backfire they are useless. What we use on the Pro-Mod cars is plastic bolts for the top plate. If it sneezes it just sheers the bolts, you replace them and away you go.

On a blower car, in addition to burst panel, they also run alum blower studs. So even when it pops panel, it still lifts the blower. You are just hoping the combo of the two keeps it from destroying the intake
