I am wondering if my engine should be running hotter for more power? I just changed to a koyo rad and have flex-a-lite duel fans with a thermostat to turn them on.

if I turn up the fan thermostat so they dont come on as often will this raise the water temp? I dont see that working because when im driving the fans wont be running anyways due to the air flow doing the fans job.

it seems cold compared to my setup. mine is usualy around 180f. not sure if it makes a different for power but imo its better than running to hot.

70-80 degrees is just the normal operating range.
