Opening the valve at 68 ℃ (Stock 78 ℃) Full opening at 83 ℃ (Stock 90 ℃)
All Honda vehicles with high power motor maintain a delicate relationship between the water temperature and the engine power. When the radiator water temperature starts rising, the ECU automatically reduces the risk (Map correction mode) by increasing the fuel and retarding the ignition timing, which results in losing power.
Not to mention the great positive impact on a large performance radiator, but it can be significantly effective with very light modification – stock radiator + low temperature thermostat + low temperature thermal switch + performance coolant.
With above mentioned light mod, the water temperature stays at around 80 ℃ on street driving.
J’s Racing recommends the use of this product in combination with the lower thermal switch ( or computer modification on cooling fan program)
