Eleven is the maximum number of consecutive days when the Torah can be read (outside of Eretz Yisrael):
If the first day of Sukkos falls on a Tuesday, then we have a reading on Monday (part of the regular weekly Torah portion), then the nine days of Sukkos/Shemini Atzeres/Simchas Torah, and then Thursday (back to the regular weekly portion).
Eleven are the weekly Torah portions (out of 54) that don't begin with the letter vav.
Correspondingly, eleven are the chapters of the first part of Tanya (also out of 54) that don't begin with the letter vav.
