I'm running standard temp tridon highflow thermostat no shroud no belt fan just Davies craig 14 inch thermo fan (because my cooler piping is in the way of standard fan otherwise would have kept it . thermo pulling air into engine bay) turbo radiator in gc all new hoses and have bypassed heater core . . Driving it very tame not on boost its sitting at 91-93 with thermo on (one bar above half way). What is everyone else's VL's average ? I feel as tho this is too high for driving like a grandpa And yes have bled coolant system properly put big funnel in top of radiator and filled it so all air can escape head . Is it possible to keep below half way on temp gauge with just thermo fan or do I need a shroud bigger radiator ? Lower temp thermostat ?

Are you sure that is the correct temp,You have used a laser temp gauge to check it is the correct temp. Dash gauges are just appox and not a true reading and can vary from car to car. Cheers Marty

Mine averages between 82-87 degrees (180-190 farenheit) just putting around, no matter what outside temp it is. Running twin AU-thermos that come on in sequence, first at 85, second at 92 degrees. Don't know what thermostat I have in mine, however, I've bought a highflow Tridon 71 degree thermostat that I'll chuck in when I upgrade my turbo.

The reading I'm getting is off of my computers (aftermarket ecu) hand controller so it should be correct although it is using the original tridon sensor . Thanks for the feed back though appreciate it ---------- Post added 25-10-14 at 22:58 ---------- Have been researching all night .
