Perrin Universal Manual Boost Controller
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 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 doesn't 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 it's lighter weight and ultra smooth surface insuring the fastest response possible.
The PERRIN Manual Boost Controller has a precision machined bleed hole that reduces the falling type boost curve that plague other boost controllers. This "tuned" bleed hole compensates for the added volume of air flow as RPM's increase and ensures a fast response as you approach your peak boost setting.
This is a major advantage in the PERRIN design and allows our boost controller to be more consistent and perform better in all applications.
This 3 part blog series written by Jeff Perrin explains how boost is regulated in a turbocharged vehicle, how aftermarket boost controllers work and when to step up to the PERRIN EBCS Pro solenoid. Included are tech notes and dyno graphs illustrating the proper use and advanced layouts for different boost control systems.
