| Product Description | By keeping the engine at the optimum water temperature, power down and overheating are suppressed. Maximize the original power! Billion Super Thermostat is a low temp thermostat that opens about 10 ° C to 20 ° C earlier than the genuine thermostat. When the engine is bench-tested by water temperature (power check of the engine alone), the water temperature that can exert the power most efficiently is about 70 ° C. Beyond that, the intake air begins to be affected by the water temperature and the intake air temperature rises. As the gas expands as the temperature rises, the floor area ratio decreases (oxygen density decreases) and power down begins. In this way, water temperature and engine power are closely related. Therefore, Billion has developed "Super Thermo" to eliminate this phenomenon. The valve opening temperature is set 10 ° C to 20 ° C lower than the normal thermostat, and the cooling water is circulated to the radiator earlier. Cooling is started before the water temperature rises completely, and the decrease in engine power due to the rise in water temperature is suppressed. |
