Temperature ?

[ITSROTARY7]

When people talk about water and oil temperatures, is that temp going into the motor or coming out of the motor. I have heard that 190* to 200* for water temp is where we make the most horsepower, but not sure where that temp is coming from. I know the stock position on a Second Gen Rx-7 is at the back of the water pump, showing the temp coming out of the motor.

Oil and water temp should be measured coming out of the engine.
