How to CORRECTLY set up capacitor bank in series? Answered

On my coil gun I currently have 24 330V 120uf capacitors in parallel. I am using multiple camera flash circuits to charge the capacitors. I want to create 3 capacitor banks of 8 in parallel linked together in series. I understand the concept of series but whenever I do it my coil gun becomes extremely weak. Do I need to switch out power supplies? 
Thanks,

How does your coil gun work when it is not weak ?

If I understand you you have three identical groups of 8 parallel capacitors
960 uF in series with each other.

Very well wired with at least  # 12 gauge wire giving you
an equivalent 320 uF capacitor at 990 VDC..

Does that sound like what you are measuring ?
