The PERRIN Manual Boost Controller is a simple inline device that allows you to set your desired boost level with a few simple twists of the body.
Applicable to most all turbocharged vehicles.
Easily adjusted by hand, the twist-to-adjust body simply shortens or lengthens to alter the spring pressure on the metering ball. This simple design only uses 5 parts and does not require any special tools to make adjustments.
At the heart of the PERRIN Manual Boost Controller is the Ball and Spring. The spring holds pressure against the metering ball, closing off boost pressure from reaching the turbochargers waste gate. Once the pressure builds to your desired setting the spring begins to collapse, the metering ball lifts and lets pressure through to the waste gate actuator limiting boost levels.
The PERRIN Manual Boost Controller incorporates a custom wound progressive rate spring and a ceramic metering ball for its lighter weight and ultra smooth surface insuring the fastest response possible.
