I was wondering, what ever happened to Air Induction Impellors?  Of course the AAA cut titanium impellors and the hyyperbolic nozzel reducers were a bit costly but the fact that once induced the pump would rev to +20% with a 75% increase in nozzel velosity while increasing the bowl pressure 95%, I always thought the costs would be far outpaced by the thrust increase. Back Then I thought we would finally outpace a TFH in the quarter?
