The Synapse Radian MBC, or manual boost controller, is a premium unit designed to give you precise control of your boost pressures. The unique 3 port design allows users to not only use it on their wastegate, either external or internal, but also allows users to pair it with a Synchronic BOV or DV to leak boost when not needed.
When used with a Synapse Blow Off Valve, the Radian 3-Port boost controller can act as a boost fuse on turbocharged cars or as a Bypass Valve / Pressure Relief Valve on supercharged applications. Using the Radian controller in this manner allows you to either protect your engine from over-boost situations or make your centrifugal/roots supercharger more efficient and gain boost more quickly!
- Adjustable ranges from 10 PSI up to 100 PSI!
- Can be paired with a Synchronic valve to act as a boost fuse on turbo applications.
- Can be used on supercharged applications to hit boost more quickly!
- Individual Boost, Vent, and Wastegate Ports.
- Proprietary Vent Port can be plumbed after the MAF Sensor to prevent a CEL.
- Vent Port is serviceable (unlike other MBC's).
- Threaded 1/8" NPT Ports for all pneumatic connections.
- Includes basic installation fittings.
- Available in different eye-catching colors.
- Manufactured from premium aluminum and stainless steel materials to precision tolerances.
Tuning Note: As with any boost controller, if used to raise boost significantly (more than 2-3 PSI) we strongly recommend ECU tuning for best performance and engine life.
