Hi Steve,

A sync spark gap lets you fire at anytime during the AC cycle.  As it turns 
out, there is a "sweet spot" for firing time at which you can charge a 
larger cap with an NST than you can with a standard static gap.  A sync gap 
lets you use that firing time and you can charge a 50% larger cap to get 
50% more power.  That sweet spot is actually after the voltage peak where a 
static gap would normally fire.

Richie has great info and graphs too at:
