David,

Well Richard Hull used approximately that cap value for
his Nemesis coil which used a 10kVA, 10kV piggie.
He used 11 to 13kVA or so and got about 15 foot sparks.
He ran at about 450 bps non-sync.  I agree that the phasing
won't be too critical at your 480 bps.  I would think your
piggie has the power to charge those caps pretty
well at 480 bps.  You could certainly compare the performance
at 240 bps and see what happens.
