Well done. I wouldn't be too unhappy with the performance. Most people
running 4 inch coils will have a 12kV 30mA coil and twice your power which
is not 180W.
NST's are rated at open circuit volts and short circuit current not both
together. Maximum power transfer is much less than that 180W if I recall.
Large toroids decrease the topload voltage but if you have the power to
spare this will increase peak spark power and propagation. Yours may be
right for your power.
