I had the pleasure of helping to do the certification test for a new "O" motor from CTI. By comparison, an "O" motor has 20,480.01 to 40,960.00 Installed Total Impulse (Newton-Seconds). Compared to a "B" motor which has 2.51 to 5.00 total thrust - a factor of 8192 times ( 213). Or, in other words, an "O" motor is equivalent to 8,192 "B" motors. Yes, a big one.
Dr. Jeroen Louwers and Bob Pouliot were also present for the testing.
