Anti Surge Compressor Housing / Patriot Boost

Optimize your Polaris Patriot Boost's capabilities with the High Flow Anti-Surge Inlet. This part is designed to maximize airflow, resulting in a increase in air volume. By preventing compressor surge, this inlet ensures consistent power output for On/Off/On throttle. 

💨 What Is Compressor Surge?

Compressor surge happens when the turbo is making more boost than the engine can take in — usually at low RPM or during throttle lift.
When that happens, the airflow through the compressor wheel stalls or reverses, creating:

• A fluttering or chuffing sound

• Stress on the turbo bearings and shaft

• Slower spool-up and possible long-term damage

⚙️ What the Anti-Surge Cover Does

The anti-surge cover has extra air ports or slots around the compressor inlet. These allow a small amount of air to recirculate from the high-pressure area near the wheel back to the inlet when the turbo starts to surge.

This controlled bleed of air:

• Prevents the airflow from stalling

• Widen the compressor map, meaning the turbo can operate efficiently over a broader range of boost and airflow

• Improves low-speed drivability (especially on larger turbos)

• Helps the turbo spool more smoothly when coming on boost

• More midrange response and quicker spool up times
