<< 	Removing the core also removes the high coupling from primary to
 secondary.  So you still will not get much out of it.  However, if you now
 tune the primary and secondary to resonance and turn it into a Tesla coil
 circuit, the voltage is then allowed to fly up to the 200X primary voltage.
  That is what I did and that is why I got very big sparks.  The operating
 frequency is also vasty improved too but the secondary will still limit the
 frequency to the 10kHz range.
 
 	This does make the GM HEI coil unique in that the cores are so easily
 removed.  The Mallary, Accell, Jacobs and other fancy rod shop coils don't
 have removable cores as far as I know.  This will eliminate them for my
 uses.  Thanks to everyone that suggested them anyway!

Terry,

I am confused about your test.  Your comments above indicate that you did
remove the core for your testing but in your comments earlier, I believe you
said you now had to cut the case off to do failure analysis.
