[Land-speed] FW: Electric water pumps

[Greg Meyers]

Thanks Skip.  The Centripuppy I used before had a bronze pump, and no
plastic parts. It was advertised at 19.5gpm at 3 ft head.  The replacement
being sold is plastic.  I suppose whatever is used should be built to
withstand perhaps 300 degrees and pressures
up to maybe 50 pounds?

In addition, to summarize what has been suggested in this thread:
You believe about 20 gpm is adequate to carry away heat from perhaps 300 hp
applied over perhaps 6 minutes, without a water reservoir beyond
conventional hoses and radiator.  A 3/4" restriction either as a thermostat
or fitting should be in the return line?
