PWR Advanced Cooling Technology 2020+ Toyota GR Yaris / GR Corolla Motorsport Radiator

Details:

During our 2023 World Time Attack Challenge testing with our own GR Yaris we encountered cooling issues, which is when we knew we the factory cooling system was not adequate for the amount of power we were making.

From here we teamed up with PWR Advanced Cooling Technology in Australia and developed a motorsport radiator that fits both a GR Yaris and GR Corolla utilising their 32mm, R-Fin and dimpled tube design core. The R-fin core is an upgrade PWR tend to use in motorsport applications as it increases the contact area with the tube. This increase in contact area is accompanied by a reduction in metal thickness meaning the core can be more dense and still maintain a similar weight to factory.

The dimpled tube is essentially an internal modification to the tube which turbulates the coolant as it passes through the core. This effectively forces the coolant to spend more time in the radiator core, allowing it the time it needs to cool.

The increase in core thickness (32mm), upgrade in fin and tube design, results in the product being slightly heavier than OEM, however it will outperform the OEM unit in heat rejection and pressure drop through the core.
