Collection: Blow off Valve & Bypass Compressor Valve
BOV or BCV: Using the proper blow off valve (BOV) or bypass compressor valve (BCV) affects the system's performance. There are two main types to consider.
1. MAP (Manifold Absolute Pressure) sensoruses either a vent-to-atmosphere valve or a recirculation valve. – Connect signal line to manifold source – Surge can occur if the spring rate is too stiff
2. MAF (Mass Air Flow) sensor uses a recirculation (bypass) valve for best drivability. – Connect signal line to manifold source – Position the valve close to the turbo outlet for best performance (if the valve can handle high temp). – Surge can occur if the valve and/or outlet plumbing are restrictive.
