Eight seconds is no problem. I was thinking in terms of about 50% of your lap time.

Is the radiator clean? Is the thermostat okay? Here is an easy performance test. Warm the engine up until it is hot. Then unplug the connector on the small sensor on the AC line next to the dipstick. Both fans will turn on. With an ambient temperature less than 80 degrees the engine should cool to 200 degrees in about two minutes. The center of the sweep on the temperature gauge is 200 degrees.

Is the oil temperature gauge correct? Use a data scanner to read the digital temperature. It comes from a separate and more accurate sensor.
