Ry,

You are correct if you're using a static spark gap.  The breakrate
will increase when more power is available, but each capacitor
discharge will remain the same.... the bang size will be the same,
but there will be a greater power throughput, and longer sparks,
as a result of the higher breakrate.  Sparks get longer due to
either a larger bang size, or a higher breakrate, or both.

If you're using a rotary gap with a fixed breakrate, the voltage
may go higher depending on the capacitor value, etc.
