springs included, 3 feet of vacuum line, mounting bracket, hardware packet and complete
installation instructions all in one kit. The Pro RX kit was designed to allow very specific
control of boost.
This kit has a ceramic ball instead of the 316 stainless ball that comes in the other
Hallman Boost Controllers. The ceramic ball only weighs a fraction of what the stainless
steel balls weighs. This weight difference allows the ceramic ball to act very quickly as
it is constantly changing directions during operation. The ceramic ball in conjunction with
the use of a lighter spring will allow very fine adjustment of boost up to 4 to 5 pounds of
boost over stock. Boost has been able to be adjusted in half pound increments very
consistently with this valve.
This kit was specifically designed for those that only wish to add a few pounds of boost
over stock and have a great amount of control over those few pounds.
This kit also includes the heavy spring for those that would like add more than 5 pounds
of boost and want to take advantage of the ceramic ball. The Pro Kit RX also includes:
3 feet of vacuum line, a mounting bracket, hardware packet and complete installation
instructions all in one kit. This kit has all the installation hardware that is needed for most
all turbo installs. Plus, it comes with a mounting clamp to hold the valve.
