WBC is a fairly interesting set up. I think the main thing is flipper speed rather than power. The ram is about 80mm in WBC1 but co2 is delivered directly from two co2 bottles through a purpose made hing directly into the base of the ram (not the side). Valves are fairly high flow pilot operated valves so it has a high and low pressure system on board. Pipes to the valves are 1/4" if that's any help with flow rates.
