manjinder,
Good question! Assuming that your coil could withstand the power
of a pole pig, yes the spark length would increase. This is because
the spark gap would fire more often. The higher break rate would
give more power throughput... and give a longer output spark. It
is also posssible that the cap would charge up to a higher voltage,
because the NST may have been "struggling" to charge the cap.
However, you would get better results by using a large cap size
for a larger bang size. If the primary gets too warm, then it's not
"strong enough" (the wire is too thin).
Cheers,
