BTW,  since the pressure cap is at the point water enters the radiator,  the
pressure in the radiator is not increased by additional water  flow.  If
anything, the pressure at the bottom outlet is decreased  (because of
increased drop across the  radiator).






I would sure be curious if there is any analytical data w/r improved  pumping 
ability. 
I say this because I once was fortunate enough to spend a bit of time  
discussing automotive water pumps (specifically the two different Stag pumps)  with 
an automotive  water pump specialist from Chrysler who belonged to our  club. 
My conclusion from that conversation was that adding vanes does not  
necessarily improve water pump performance. Does anyone know if there is  credible 
evidence that it improves cooling in this case?
Thanks, Mike Moore
