Agency Power Adjustable Blow Off Valve Polaris RZR XP Turbo



Adding a vent to atmosphere Blow Off Valve on the Polaris RZR turbo system is a great way to improve throttle response and hear that awesome blow off valve turbo sound.  With an ECU tune and higher boost levels, the Polaris RZR can gain 10-15% more power over stock.  However the stock plastic diverter valve is ill equipped to handle this increase.  One option is to replace this valve with an aftermarket diverter valve like Agency Power also offers.  But for those that want to hear the whoooosh sound, there is this adjustable vent to atmosphere blow off valve!  The purpose of a BOV is not just to sound cool, but it is designed to release the pressure that is built up in the charge side of the system.  The factory diverter valve system dumps this pressure back down into the intake pipe.  This can cause turbulence to the impeller, slowing the spool of the turbo down and causing premature wear. 

The Agency Power blow off valve for the Polaris RZR can be used in conjunction with the stock turbo inlet pipe or any aftermarket turbo hose pipe that has a 1 inch BOV flange.  Since the factory valve is a diverter valve and this new valve is designed to be 100% vent to atmosphere, we include a high-temp push on plug cover for the eliminated return hose.  Each Agency Power valve is machined from 6061 billet aluminum then anodized in a stealth black finish.  The top is laser engraved with the Agency Power cursive logo and directions for adjusting.  When the top of the valve rotates, this allows you to adjust the spring tension for your application.  You can set the valve to easily vent off pressure or be stiffer to only vent at maximum PSI.
