■A water temperature of around 70 to 80°C is the range that maximizes engine power.
■If it rises any higher, a sudden drop in power will occur.
■As the water temperature rises, knocking symptoms will occur in the combustion chamber and the ECU will increase the amount of fuel and retard the ignition timing.
■The starting temperature has been lowered by 13 degrees from the original normal temperature of 93°C to 80°C.
■At the same time, measures to lower the water temperature are also necessary, such as a large-capacity aluminum radiator, an opening in the bumper to increase air flow, and an outlet structure in the bonnet.
