Todd,
This is really great information.  I'm glad that you
found this through your research into EWP.  

I've been following this thread closely, but I haven'y
had anything to add, since I'm only using the stock
water pump.

The idea of a redundant pump, in case of failure,
and/or for use on the ground to suppliment cooling at
low RPMs is of great interest to me.

I guess I'll sit back and see where all of this goes.
