rj Posted September 24, 2017 Share Posted September 24, 2017 Can anyone direct me to an image of the said installation.My searches have directed me to threads where the links don't work Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted September 24, 2017 Member Share Posted September 24, 2017 Titanium7's, but I'm not sure what type he used.Have you already got the circuit diagram?Jonathan Link to comment Share on other sites More sharing options...
LesG Posted September 24, 2017 Share Posted September 24, 2017 It's really quite easy to do, and mine has worked perfectly since I installed it. Mail me your contact details and I'll sort you a couple of pics. Link to comment Share on other sites More sharing options...
rj Posted September 24, 2017 Author Share Posted September 24, 2017 Les,YHM.Jonathan, now I do. Many thanks. That was about what I had figured out myself, so I'm confident now :-)I am also going to fit an electric water pump that kiks in if the temperature rises after stopping the car. I have had a few issues on trackdays in cold-ish weather. Temperature is rock steady whilst on the circuit, but when the car gets to the pit it overheats. Fan goes on as it should (and runs the right way) but still it blows off the water (!) .I will be altering the wiring to enable the fan to run with engine off - and the external water pump will be in the same circuit. The old thermostat housing will be replaced with a home made fitting that goes directly to the external water pump.If this does not cure the overheating scrapyard will be next measure taken*curse*.

Area Representative Golf Juliet Tango Posted September 24, 2017 Area Representative Share Posted September 24, 2017 I have wondered, several times, if it might be worth having an electric watr pump on a parallel conduit, which operated on an over-run; so would distribute heat aftrr the engine was switched off. After a hard session on track, does anyone worry about localised hot-spots cooling differentially? Link to comment Share on other sites More sharing options...
Ivaan Posted September 24, 2017 Share Posted September 24, 2017 I guess if you're racing you'd have a cool down lap. On track days, you tend to head straight to the pits whilst going at full chat for most of the lap. Link to comment Share on other sites More sharing options...
rj Posted September 24, 2017 Author Share Posted September 24, 2017 Nope. Always at least one and often two laps to cool down at a reasonable pace This for both engine and tyres. Only direct to pit if something unexpected has happened. Link to comment Share on other sites More sharing options...
rj Posted October 9, 2017 Author Share Posted October 9, 2017 So,I plumbed in the remote thermostat, removed the old thermostat housing and fabricated a tube that connected to an electric water pump like thishttp://daviescraig.com.au/product/ewp80-electric-water-pump/ewp80-electric-water-pumpThe pump is just operated by a thermo-contact off an Audi; it was supposed to switch on at 85 degrees and off at 80, but in reality on is at 68 off at 58. I have braced in a brass boss in the water rail at the straight piece between header 2 & 3.I was off to a trackday yesterday. We were a total of five drivers, the car was well hooned and had its breaks, where it used to overheat whilst idling in the paddoc. We simply stopped the engine but left ignition on which enables the fan and the electric pump to run. (I have yet to alter the wiring to leave power for fan (and now water pump on with ignition off)The maximum temperature ever seen was 83 degrees - and on the circuit the temperature was rock steady at 75 degrees, just like before.Problem solved.Only downside is the extra weight of the pump and water but if it saves the engine I can live with it.
