i have two spare Liberty pumps $150 each if any one wants one!!
Purple_Beasty was right about one thing MUCH less pressure drop and short plumbing .i think a liberty unit tested at less than 0.5 psi pressure drop and if you modify the outlet they flow even better .
water to air siuts blowers better as more boost is a lot more hassle and long plumbing takes way the instant power advantage of supercharging .In effect the big volume creates lag
