hey guys wat is the ideal running temp. for the rb30 turbo motor ? im installing the twin au fans and need to know wat to set the thermo switch to... between 80 - 115 deg. thnx

Should be no more than 3rd bar on the Temp Gauge.

well i did a bit of searching .. ppl have said their vlts run anywhere between 76 - 96 ? ... so by that i could guess that setting my thermos to 80 deg should be about right ?

I would say turn on at 105c and of at 95c if your temp swicth is in the top hose/tank.the t/stat is a 76.5c which means around 90c/95c on the top.Much lower than that u run the risk of cooling the rad to much closing the t/stat and so on.

It should activate the thermo at anything over 87degree's on the rb30's. 2 speed fan is ideal, 87degree's low, 92degree's high. 81-85 is normal running temp.

my mechanic said he will set the thermo switch to 170*F which is 77*C, will he just buy a switch that sets the fans off at 77*C? or is it controlled some other way? cheers

the thermostat would still be closed at 77c so having the fans on is pointless. you want the fans on when the thermostat is open, so around 85-90

Why not just keep the standard clutch fan?

I have a thermo on my car and i have it set to come on at 95C. running temp is 90 so 95 is good because when it turns off it is back to 90.
