Hi,
	Your not using a pipe are you?  The flux would be way to high on 
the little amount of iron you have and would probably saturate below 
30 volts unless you added a lot more turns in series.  Since the flux 
wouldn't have a closed path your mutual inductance will be really low.
This means that you will have an efficiency less than 25%.  If you 
want to make a good/decent HV transformer get a real transformer 
core.

	I am not trying to bite your head off I am just trying to stop you from 
making that pretty smoke and wondering why it didn't work.
