I'm not sure, but I may have just found my problem. While on John Freau's 
website

I read that a lower bps coil will require a larger, taller secondary and 
toroid to handle the larger bang size to prevent racing sparks (!!!!) and 
premature breakout from the toroid. Having a LTR primary capacitor and a 
semi-wide static spark gap, I would imagine that I have a low bps, but high 
bang size each time the gap fires. (If I am missing something somebody 
please let me know) My secondary is quite short ( 6 inch diameter, 24 
inches tall, 3.84 H/D aspect with 22 gauge wire) so I suspect this might be 
the culprit. Am I correct on this? If so, the only real options would be to 
keep the coil undercoupled (which would mean a wimpy coil =/ ) or wind a 
much taller secondary (I'm thinking something like 31.25 inches tall, for a 
H/D aspect of 5?) Any ideas on this? I want to make sure I have the right 
clue about this before I start trying things =D
