For reference, the Space Shuttle SRBs were 2800k each at launch and bumped up over 3000k. This chart is a little nuts:

It's true the SRBs were powerful, but I wonder how much of that was compensated by structural elements needed to live with their vibrations. I remember the original Ares I concept would vibrate the astronauts to death before the solid 1st stage burned out.
