Manual Boost Controller
List Price: $89.99
Our Price: $79.99
A great way to add horsepower and torque to your turbo charged engine is by introducing a higher level of boost. Many factory turbo charged vehicles (e.g. WRX, STi, EVO 8, MAZDASPEED etc.) have factory boost management that can vary boost level. Boost levels can vary based on gear, RPM, throttle position and more. With the simple installation of the PERRIN Performance boost controller you regain the ability to change and/or hold boost at whatever level you choose. This flexibility will increase low end boost response (in some cases as much as 750 RPM sooner than stock) in all gears and allow upper end increases in boost level. All will net a much faster vehicle without sacrifices to drivability.
The PERRIN Performance boost controller features a custom wound spring and ceramic metering ball for boost management. Months of testing with different spring rates and ball compositions allowed PERRIN to achieve the perfect balance of level and response. The lightweight ball and spring also prevent dangerous over-boosting found in other competitive units.
The PERRIN boost controller is easy to install and easy to adjust. Most shade-tree mechanics can install and be enjoying their new power in less than 30 minutes. Using indicator marks around the body of controller, the user can make adjustments in small or large increments (as fine a 1/4 lb!) Basic instructions, connectors, silicone hose and mounting hardware are all included with the controller. Some simple hand tools are all that's required to perform a professional installation.
