Features & Descriptions
 
What is the HPI EVOLVE Radiator? 
The EVOLVE Radiator is engineered to push your vehicle's performance to the next level.
It suppresses water temperature rise during circuit and sports driving, while ensuring temperature stability even under low-airflow conditions, such as city traffic jams.
By optimizing the core width, fin shape, and pitch design, it provides reliable cooling performance across all driving stages—from stock vehicles to fully tuned cars.
 
What is the Standard Series? 
The Standard Series utilizes a core design that boasts an overwhelming coolant capacity.
Delivering outstanding cooling efficiency, this model effectively suppresses water temperature rise relative to the number of laps.
It is specifically built to handle demanding conditions where airflow is limited, such as drift sessions or driving on mini-circuits.
 
What is the Light SH Series? 
The Light SH Series features a slim-core design aimed at reducing weight and minimizing modifications required during installation.
By promoting enhanced self-heat dissipation, it accelerates water temperature drop during cooling laps, delivering highly stable cooling effects.
This model adapts to a wide range of driving styles, making it perfect for both street-driven vehicles looking for an OEM replacement and lightly tuned cars for sports driving.
 
What is the Multi Flow Series? 
The Multi Flow Series features high-capacity tanks positioned on both sides of the core.
By routing the coolant to turn within the tanks, the fluid passes through the core multiple times for repeated cooling.
This design maximizes heat exchange within a limited surface area over an extended period, delivering unmatched cooling performance and temperature stability even during continuous track sessions.
It provides definitive cooling effects even via airflow from electric fans while stationary after driving.
This model is highly recommended for circuit use and vehicles requiring cooling performance beyond alpha-level upgrades.
 
What is the Control Plate? 
For vehicle models where the lower hose inlet is located directly beneath the upper hose inlet, a uniquely developed Control Plate is built inside the upper tank.
By implementing this plate to control water flow, the coolant flowing from the upper side to the lower side is evenly distributed across the entire radiator, achieving highly efficient cooling performance.
 
What is the Micro Pitch? 
By making the pitch of the fins and tubes finer than usual, the radiator achieves superior heat dissipation.
This ensures further stability of water temperatures even under severe conditions, such as sports or circuit driving.
Each unit is custom-designed to optimize cooling efficiency, taking into account the unique engine bay layouts and coolant flow of different vehicle models.
