RZR Supercharger Specifications
Lubrication is accomplished with a highly special high grade type of traction fluid. The unit utilizes positive pressure created by boost as well as an internal pump to circulate the fluid. This is a closed loop system. Includes Billet reservoir with temp sensor, filter and oil cooler. Only use supplied Rotrex Traction Fluid.
Belt Drive System - Connected directly to the crank and transmitted to the blower via a cog belt drive system.
A stub shaft is connected to the end of the crankshaft on the magneto side of the motor. Strength is a null issue. The stub shaft is stronger and more durable than the crankshaft itself. Internal crank end sizing and bearing will support 8 times the horsepower that is actually used to drive the blower.
The OEM side cover is modified to allow the New PTO Shaft to Exit. You can purchase a new modified cover for about $100 or have yours modified for free.
A cog belt design was chosen due to long life, no chance of slippage due to tension or snow and minimal tension requirements. Belt construction is the same design used in snowmobile belt drives. Although only 20mm wide, our belt sports a safety factor 3-1/2 times higher than the industry accepted belt drive, since we are transmitting less than 10HP and belt drives transmit over 100HP.
The systems plumbing, although simple, is 1st class. All components are aluminum with stainless clamps.
The Charge Air Tube (or CAC tube) is mandrel bent aluminum and less than 24" long. All connections are made with silicone hose and stainless steel Tee Clamps.
The Inter cooler & Air box are design and constructed entirely of aluminum and utilizes a bar and plate inter cooler core capable of supplying motors over 180HP. Pressure drop across the core is less than 1/4lb. Air intake temperatures are typically between 30 to 50 degrees above the ambient air temperature.
Connection to the throttle body is an optimized design employing silicone hose & stainless constant tension clamps. This design can sustain boost numbers in excess of 25 psi.
The RZR employs an Automotive EFI style Fuel system.
Power to the pump is electronically controlled through the OEM computer.
All electrical connections are made by plugging into or bolting onto the OEM wiring system. No splices are used and no wires are cut!
The Fuel system is converted to a return style system with a 1 to 1 rising rate regulator.
The entire fuel system uses Extra Heavy Duty 300 PSI fuel line. This line maintains extreme flexibility under the harshest temperature changes and is impervious to any fuel or fuel additives. All connections are made with constant tension stainless hose clamps.
The Kit Includes a New 100% Stainless Exhaust System.
High Performance RZR Exhaust System saves weight but increases dB levels.
Oiling systems.
The OEM system is unmodified!
The blower's oiling system is self-contained.
It employs an external filter, reservoir and oil cooler. This allows the owner to easily check the oil level. Oil changes are recommended once a year or every 50,000 miles (which ever comes 1st).
The blower system includes an 1/8" NPT port to monitor oil temperature. We recommended adding an oil temperature gauge for extreme applications or applications in hot climates.
Blower and drive mounting.
Components are made of billet aluminum and connect 100% into existing bolt holes.
The A-Arm Bracket is modified on the Right Rear Side to provide clearance for the Supercharger Drive. The modification is quite simple and in no way sacrifices strength.
Due to an Inconsistency in Polaris Engine Manufacturing, we are recommending that all units running on pump gas check the piston ring end gap. Most units are OK, but we have seen several units with less than 0.010" of end gap. We recommend opening this gap to 0.020 to 0.024"
Base line boost recommended is 6psi. The system is capable of 14+ psi, but requires motor modifications.
This unit carries a 1 year warranty for off road application.
