Paul,
I just got a Summit catalogue which, ta da!-has  TWO! electric water pump
for rx7s. Summit is being drawn into the import  drag racing circuit.
Meziere MER-WP116SHD, supposedly a heavy duty kit, $269.95, and a standard
duty kit for $249.95. You "eliminate" the OEM pump (!). Made from 6061
billet, says it comes with conversion kit and mounting. Also offered is
Mazda rotary "adaptor block kit" MEZ-WP90, allowing mounting of the pump
directly to the engine. 2 3/4" NPT inlets, and one 1" npt outlet.
Wonder how this thing would hold up to continuous duty? Might make a nifty
back up pump.

What is the current drain? Multiply the current drain by 12 and divide
by 746 to get the HP. If it is less than 2 good luck on cooling the
engine at high continuos power levels. A drag car can run a few seconds 
without a water pump. Some do.

Summit is not too picky about truth in advertising.
The Moroso ad says "save up to 20 HP".
For equivalent cooling that would require an electric pump
drawing 1,243 amps!!!!! from the battery.

The CSI ad claims 30 gpm at only 5.8 amps or .09 HP. Good Luck!!!
At least they don't say how much HP it saves.

Power Sport tested one of these and they don't put out anywhere
near they flow they claim.

Please... PLEASEno more messages about silly electric water pumps.
They make even less sense than putting your engine in there plugs up!
