Technical heatsink fitment for Savage engines

This precision heatsink is designed to increase fin surface area around HPI Savage 21, Savage 25 and Savage X 13 engine heads and is published under part code HSA-027/B. The extra fins improve passive heat transfer from the head into the surrounding air without changing ignition or carburetion parameters.

Fitment replaces the factory head cooling component and uses the stock mounting points. During installation align the fins to avoid contact with the tuned pipe or header, hand-start the fasteners, then secure to the engine maker recommended torque values using a medium strength thread-lock where specified.

From a setup viewpoint the heatsink provides thermal stability rather than power gains. Reduced peak head temperatures under sustained loads help maintain consistent running for practice and race tuning sessions.

What heads is HSA-027/B intended for?

It is intended for HPI Savage 21, Savage 25 and Savage X 13 heads. Check your head-to-exhaust clearances before final installation.

Any special torque or thread-lock guidance?

Use the torque and thread-lock recommendations in your engine manual. Start screws by hand, confirm alignment, then torque to spec to avoid distortion of the head or striping threads.

How does this affect thermal management?

As a passive device it increases convective surface area to lower peak temperatures under load, improving thermal consistency for tuning and extended running sessions.
