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 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.
