Is time important

Hi all,
         Just a quick question I have a really big (for the coil its on)
torroid made out of a old truck tire inner. When i turn my coil on (see
specs below) nothing happens, instantly. If i left it run for a while
would it eventually build up charge and shoot a really big spark? Does
time have anything to do with it?
Would greatly appreciate any help.

                                                            Thanx Paul
