Other than a tweet? Well, one could try plugging the available numbers into the rocket equation. I've taken them from http://www.spaceflight101.net/falcon-9-v11.html (accuracy is probably debatable, plus the numbers are old, so a grain of salt is advised). Average specific impulse (in seconds, yech) could be a bit more than 300 s, let's say v_e = 3000 m/s effective exhaust velocity. m_full = 418.8 tons. m_empty = 23.1 tons. v_max = v_e * ln(m_full/m_empty) = 8700 m/s. Probably not quite enough, and certainly not useful (I've left out any payload and the aerodynamic nose cone).
