Bikeman Performance High-Flow Anti-Surge Compressor Housing Kit for Patriot Boost "Big Mo" Turbo // SKU: 14-214-KIT

SKU: 14-214-KIT

Primary Application: Polaris Patriot Boost models upgraded with the Bikeman Performance "Big Mo" Turbocharger platform.

Maximize the high-CFM output of your upgraded turbocharger while completely suppressing compressor surge with the Bikeman Performance High-Flow Anti-Surge Compressor Housing Kit for Big Mo Turbochargers. Engineered specifically to match the larger compressor wheel profile and extreme volume capabilities of our "Big Mo" Patriot Boost turbo upgrade, this housing ensures uncompromised airflow delivery and instant boost response.

Featuring a massive 3.0-inch high-flow intake inlet combined with engineered anti-surge recirculation slots, this housing prevents air stall during aggressive on-and-off throttle riding. By allowing trapped backpressure to bleed off smoothly when chopping the gas, your "Big Mo" turbo maintains high wheel speed, eliminates power lag upon re-entry, and protects high-dollar internal turbo bearings from severe shock loading.

Kit Includes:

• Bikeman "Big Mo" Anti-Surge Compressor Housing: Custom-contoured billet aluminum compressor cover (SKU: 14-214) machined specifically for Bikeman "Big Mo" turbo wheel geometry with 3.0" inlet and anti-surge porting.
• Bikeman 3.0" High-Flow Silicone Intake Tube (Black): Multi-ply reinforced 3.0" silicone intake tube (SKU: 14-206) designed to handle elevated suction and boost pressures.

Key Performance Features

• Engineered for "Big Mo" Turbo Flow: Custom internal volute and anti-surge porting contoured specifically to match upgraded "Big Mo" compressor wheel dynamics.
• Eliminates Compressor Flutter & Surge: Anti-surge bypass channels prevent destructive pressure spikes against the compressor wheel during quick throttle lifts.
• 3.0" High-Flow Intake Geometry: Feeds maximum CFM air volume directly to the compressor wheel, shortening spool time and enhancing top-end power.
• Bearing & Shaft Protection: Reduces mechanical strain and thrust-bearing shock under high boost pressures.
• Razor-Sharp Backshift & Throttle Recovery: Keeps turbine momentum high so boost is instantly available when rolling back into the throttle in technical terrain.
