Heat produced vs heat removed. There will be a steady state at some point. You would like it lower. Don"t underestimate the headgasket component of channeling coolant flow. In the TR4 motor i made the coolant holes different than original to allow the mass flow of water to occur from the rear of the motor forward. I also put a pressure gauge on my coolant. If the pressure is too low it will not cool as efficiently either. I don"t know what the coolant dwell time with in the head needs to be to in order to adsorb the heat generated. Nor the dwell time in the radiator. There certainly calcs for all this stuff. <br>

<div class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana",sans-serif;color:#1F497D" lang="EN-US">My TR8 is running way too hot about 212F at full speed and at idle the temps are getting that high also. I have no idea to get them down.<br>
Radiator core is 68x48cm x 5 cm. I suppose that should be enough. I've experiment with different restrictor plates with no change. Changing pump speed didn't help either. The difference between radiator in and outlet is 10°C (50F). Not enough I would say. Maybe making the pump more slower? It was running on a ratio of 0.8 slower than crank, currently 1:1 speed. </span><span style="font-size:10.0pt;font-family:"Verdana",sans-serif;color:#1F497D">Any ideas? 10 Liters are circulating.</span></div>
