   In the Dumbo reactor paper cited here several times over the past decade,   
   Appendix D ("The Super-Dumbo") includes some analysis of the dissociation   
   potential of the Dumbo design:   
      
   "The Dumbo models given in Chap. 9 heat the propellant to a temperature in   
   the range of 2500-3050 degrees K at operating temperatures in the range of   
   15-100 bar."   
      
   Would that fall in the range you discussed?   
      
   Of course, Dumbo was pretty much a design study; only one unit was built,   
   and that one was tested with a suboptimal nozzle, so this remains largely in   
   the realm of guesswork.
