fentuz Posted April 1, 2013 Posted April 1, 2013 I was reading a thread about charge-cooler system etc which uses this type of electric pump: http://www.jjcraceandrally.com/race/electric-water-pumps/davies-craig-ebp-electric-water-pump Since I have a EP remote thermostat, the coolant small loop (cockpit heater matrix) is always opened so I was thinking that it should be easy to remove a hose in the front compartment and introduce such pump there and run some wires with a control switch. Like that, after a track session, i could leave it switch on while the engine is off and the free running coolant would dissipate the extra heat. What do you think? Cheers bill
Martin R Posted April 1, 2013 Posted April 1, 2013 Bill, i have been giving this matter some thought myself for when my new head arrives. That should work on your system. Have you done a manual fan override switch. Very useful when in heavy traffic or cooling down on trackdays.
fentuz Posted April 1, 2013 Author Posted April 1, 2013 At the moment, not overwrite switch but the emerald kicks in at 97deg rather than 102 (oem) I guess the other issue is flow reduction, is the pump on free roller? if the flow generated by the engine is greater, will the pump rotor run free and will the extra flow not be damaging the pump?
Martin R Posted April 1, 2013 Posted April 1, 2013 Bill, if it were me i would set it lower than that. I dont know what yours normally runs at? I would set it up about 5 degrees above the normal running temp. The only time it normally gets hot will be in traffic or after a heavy track session and you stop / slow down. The OE pump at tick over cant pump enough to lower the temp. Hence the override switch to help. You could always sit with you foot on the loud pedal and keep the revs up. This helps but makes you look a bit silly in the traffic in France
