Terry,
I read about your unique way of driving ignition coils and if I understand 
correctly, you removed the iron core from the ignition coil. I don't 
believe an ignition coil that still has an iron core will stand up to 10 
kHz input. I'm I understanding your description properly? If so, I might 
try this with one of my Accel Super coils and see what kind of sparks I can 
get from one of them.

I'm really impressed at your 13.5" sparks with the HEI coils. I must say 
that I'm not surprised in the least, since it is you that did it!! Do you 
HAVE TO set the bar so high all the time!!! {:-)

PS After I finish fooling with the Super coils, I think I might take a go 
at your HEI record.
