I know that this is different. The temperature of the water drops under WOT because in the thermostat there is an additional heater opening thermostat exactly under WOT.
For change thermostats 2 reasons:
1. 95% of the time the engine does not work under WOT, but in modes 0-30% of the throttle. In this mode with the factory thermostat will be 225 degrees, and with tuning thermostats will be 200 degrees. In my experience, a decrease in temperature by 25 degrees during 95% of the operation increases the life of the oil seals by about 3 times.
2. Under WOT, oil and water will have a starting point from 200 degrees and not from 225. And after a couple of accelerations, the oil temperature will increase to 210-215 degrees and not to 230-235.
