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
