TURBO ACCESSORIES

The Evolution Powersports Polaris RZR XP Turbo blow off valve (BOV) is constructed of anodized billet aluminum and features very high temperature sealing o-rings and custom spring rates matched to the Polaris turbo system. The OEM Polaris part is constructed of plastic and is a very low quality part which is prone to sticking open which will dump boost pressure to atmosphere and will cause a loss in power. The EVOPS BOV is a precision part that is designed for high performance vehicles. Because this blow off valve vents to atmosphere, you can hear the valve blowing off boost pressure which is what most turbo fanatics want to hear! This valve is recommended for sand/trail use only and comes with a prefilter to keep out dust/dirt. Mud bogging customers should purchase part # TU-PRZRT-925-BRV which vents back into the intake.

• Direct replacement for the OEM Polaris plastic valve
• Tested to 500+ horsepower
• Billet anodized aluminum construction with high temperature sealing rings
• Does not stick like the OEM valve is prone to
• Has the “Blow Off Valve” sound that turbo customers crave
• Includes a pre filter to keep dirt/sand out of the valve
• Not recommeded for mud bogging. Customers who submerge their vehicles should order part # TU-PRZRT-925-BRV

What is an air/oil separator or “catch can” and why do you need one? The factory recirculates crankcase air back into the intake. This air contains oil, moisture and other combustion byproducts which contaminates the air that is being fed to the turbocharger. The oil and water infused air coats the turbocharger compressor blades, charge tubes, inter cooler and intake valves. It can also change the air/fuel ratio and lower the effective octane of the mixture being introduced into the cylinder. Oil has a very low knock threshold, therefore the more oil contained in the incoming air, the lower the effective knock protection of whatever fuel is being used.

The EVP Air/Oil Separator or “Catch Can” is designed specifically for the Can Am X3 and eliminates the issues described above. Our CNC machined billet aluminum separator mounts to the frame rail above the clutch housing. The OEM crankcase vent hose is simply rerouted to the new location. The EVP separator has a cleanable filter element, pre filter and features a port at the bottom for periodic emptying of the contaminants. A silicone cap is supplied to block off the port on the intake boot where the OEM breather hose is connected. All hardware is stainless steel and the body of the separator is powder coated black.

The Maverick X3 Vent to Atmosphere Blow Off Valve (BOV)  kit is now complete. High performance turbo systems require a BOV when running higher than stock boost pressures.  The reason is turbochargers continue to force air into the charge tubes and intercooler even after you lift off the pedal (which closes the throttle).  Pumping air against a closed throttle super heats the air in the charge tubes and is damaging to the turbocharger bearing system.  Installing a BOV allows this pressure to be released upon the closing of the throttle which increases throttle response in on/off/on throttle conditions by venting the the hot compressed air. 

The  Maverick X3 required extensive testing of various EVP spec springs to get the right balance of responsiveness and performance.  Our X3 Turbo blow off valve is CNC machined from a billet aluminum slug.  After tolerances are verified, the piston and body are Teflon coated.    Extreme temperature Viton sealing o-rings are used for long service life.   Our BOV’s are designed specifically for offroad, small displacement engines and not adapted from larger road use vehicles.  We are the only powersports company that designs BOV’s  specifically for each vehicle. We even include a custom fitted filter with every kit to keep dirt and debris out of the BOV outlet ports!

• Requires the EVP silicone charge tube set with integrated BOV port
• Tested to 500+ horsepower
• Simple install, no drilling required.
• Billet aluminum, Teflon coated construction with high temperature Viton sealing rings
• Has the “Blow Off Valve” sound that turbo customers crave
• Includes a pre filter to keep dirt/sand out of the valve exhaust ports

• NEW- All turbos are VSR balanced
  • Only top turbo shops in the country have VSR balancing equipment as the machine costs more than $50,000.00. VSR Balancing is absolutely vital to turbocharger longevity at high boost pressures. The balancing process involves spinning the rotating assembly of the turbo to speeds that the components will see in the field.  By doing this, the smallest imbalance can be rectified.  This provides for the quickest spool and longest service life. VSR balancing is not the same as balancing!!!  Most rebuilt and aftermarket turbos are NOT VSR balanced.  All EVP Stage 6 turbos come with a VSR balance report. 
• NEW – includes a TiAL billet aluminum wastegate.
• NEW– Now with V-Map Multi Map option!  This allows customers to use the Sport/ECO mode switch to change tunes!  Sport Mode is 110 Octane and Eco Mode is 93 Octane. Comes with a replacement locking switch to prevent accidentally switching from 93 Octane to 110 Octane.
• NEW– EVP has cast our own compressor for better flow and durability!
• NO CORE REQUIRED so you are free to keep or sell your old turbocharger!

Stage 6 “Sandblaster” features:

• Absolutely the easiest turbo upgrade you will ever do – installation takes less than 3 hours and there is no need to remove the stock header!
• (2) direct replacement 3 bar map sensors with plug n play harness
• 100% Evolution Powersports ECU tuned – no piggybacks or extra injectors
• New turbocharger CHRA, wastegate actuator and compressor cover, oil supply hose and fittings. THIS IS NOT JUST A COMPRESSOR UPGRADE BUT A WHOLE NEW TURBO
• Higher volume fuel pump – (17’s include the 18 fuel pump assembly with our higher volume pump installed) with plug n play harness
• Detailed instructions
• Over 400 kits sold
• FULL AFTERMARKET EXHAUST REQUIRED!!!

NEW V2.0 – We have completely revamped our turbo upgrade for the XP Turbo and Turbo S!  New features:

• NEW- All turbos are VSR balanced
• Only top turbo shops in the country have VSR balancing equipment as the machine costs more than $50,000.00. VSR Balancing is absolutely vital to turbocharger longevity at high boost pressures.

The Evolution Powersports Polaris RZR XP Turbo diverter valve (Blow off valve) is constructed of anodized billet aluminum and features very high temperature sealing o-rings. The OEM Polaris part is constructed of plastic and is a very low quality part which is prone to sticking open which will dump boost pressure to back into the intake and will cause a loss in power. The EVOPS BOV is a precision part that is designed for high performance vehicles (it has been tested to over 500 hp!) and is a direct replacement for the OEM valve. Many different spring rates have been tried to maximize the performance and fine tune the transition from where the valve is open/closed for smaller displacement turbo/supercharged vehicles.
