Polaris 850 Turbo Blow Off Valve ( BOV ) Kit

RPM Polaris 850 Turbo BOV Kit RPM is not new to the BOV industry by any means. We have created this BOV and its spring rate specifically for the factory 850 Turbo Polaris based on its vacuum drawn at idle and while NOT under boost. Our kit uses a Patent Pending boost refence port that installs post TB's and before the reed valves.  The RPM BOV kit not only improves throttle response but takes the stress of the turbo flutter off the turbine wheel allowing for quicker spool times. This kit does require the use of the RPM Polaris 850 Charge Tube for BOV installation.  This installation can be done on the machine safely by an experienced mechanic. Basic mechanical abilities allow this to be installed with the throttle bodies off as well.
