X50 50mm Blow-Off Valve

The VS Racing 50mm BOV, specifically the X50 model, is a blow-off valve designed to release excess boost pressure from turbocharged engines. This unit is constructed with an AL flange and comes complete with all required hardware for installation. This blow-off valve includes two distinct spring configurations to accommodate various engine setups. The pre-installed spring is calibrated for high vacuum conditions, typically ranging from 18 to 22 inches of vacuum. An additional spring is provided in the box, designed for lower vacuum environments, making it suitable for applications like LS motors where vacuum levels range from 10 to 14 inches. This dual-spring system allows for precise tuning of boost pressure release based on engine requirements. As a component in the Air and Fuel system category, this blow-off valve plays a crucial role in managing turbocharger performance by preventing compressor surge.
