Race Oriented Cooling Upgrade

Engineered for competitive setups, the 3Racing 3RAC-MHS4/TI/V2 uses titanium to improve heat conduction away from the motor can, helping to stabilise temperatures over repeated high load runs.

Racing Grade Features

  • Material: Titanium provides a balance of thermal transfer and resistance to fatigue for demanding track use.
  • Design: High finger fin arrangement maximises exposed area to accelerate passive heat dissipation in tuning and race scenarios.
  • Compatibility: Specified for 540 motor can sizes to ensure consistent fitment across typical racing motors.
  • Cooling System: Integrated fan supplies forced airflow to counteract heat buildup during extended high power periods.

How does this affect temperature management during race runs?

The combination of increased surface area and active airflow lowers peak temperatures and helps maintain output across consecutive laps, reducing thermal degradation.

Are there recommended tuning changes when adding the heat sink?

No major tuning is required, but monitor motor temps to fine tune gearing and throttle profiles for optimal performance with the improved cooling.

Is this a cost effective upgrade for race teams?

It is a pragmatic upgrade for teams looking to control motor temperatures and extend component life without extensive modifications to the powertrain.
