6250 HP  is about 4660 kW.. Applying the 1.7*sqrt(watts) equation I get a
spark length of about 3670 inches, or around 300 feet...

Looking at some other very high powered coils, I see that the max spark
length is typically around 3 times the height of the coil, so you'd need a
100 foot high coil.  Winding this at a 5:1 aspect ratio, it would be about
20 feet in diameter...

Actually, this is in the size range of Greg Leyh's ALF..and as I recall that
was 5 MW?
