Richard,

That's a lot of power for a small coil, so it should give much
longer sparks.  Maybe it's not really tuned properly?  You could
try an air blast across the gap.  With that much power the gap is
probably
power arcing which can destroy the spark length.  You could try
just one NST, and it might work better, depending on the cap size.
