[TR] Alloy Water Pump

[v6spitfireguy at cox.net]

Just adding vanes, if it doesn't improve coolant flow, will not improve
cooling (that is to say that there is a problem with cooling in the first
place).  However, if adding vanes DOES improve the coolant flow, then yes
cooling would be improved - (this is of course assuming that there is an
adequately sized radiator, correct pressure, no leaks, etc.).

Check out Stewart water pumps for details on pump flow vs cooling
effectiveness -

-----------------

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
