> Theoretically above some classified altitude the Blackbird can go much faster than Mach 3 and keep on going until the airframe melts away at some crazy high, theoretical speed no one has bothered to check.

I'm very skeptical of these rumors. The SR-71 inlets were shaped for a specific range of mach numbers, and wouldn't work beyond that. Significant new engineering would be needed to go well beyond mach 3.5.

Using MagnetoHydroDynamic, you can. You just have to use parietal Engine invented by Jean-Pierre Petit in 1975[1]. With this technology you can fly at Mach 8, easily..
