I did find an old post about the CSR electric water pump here : http://forums.hybrid...csr-water-pump/
Just wondering who else runs an electric pump setup??
My reasons why I am looking into going electric.
1- an attempt to control heat spike cycling, and reduce head gasket wear.
2- free up wasted HP
I have also seen a setup around HBZ that a guy made a bracket and used an electric motor to turn the stock water pump.
Right now I am researching water flow values for the stock nissan water pump. I ASSUME ABOUT 33 TO 36GPH??
The stand alone water pump from MSA: http://www.thezstore...ZS/PROD/16-7025
I like this unit and coupled with a Davies electronic control unit it should work with what I am planning..
My current setup: Turbo charged L28, ebay 3 row aluminum radiator, 1982 turbo water pump, custom heater core (all in 1 unit for a jeep). I do not use the thermostat bypass hose setup as my heater core is free flowing I.E. it has no off valves. It flows from off the back of the head, thru the dash core, and then back to the water pump. 190F thermostat. My Z has a thermal cycle from 190F to about 220 if I'm driving hard, and 190F to 205F on cruze. The temp guage shows a lot of thermal temp cycling unless its 85F+ outside, then it stays about 200F solid.
I am concerned about all that thermal cycling and premature head gasket failure. My hope is that I may be able to control that thermal cycle better with a stand alone electric water pump and control system...
