RHINO 
Stage I Supercharger Specs

Stage I Specifications:

• Centrifugal Supercharger - Exactly the same as the compressor side of a turbo. The Compressor's impeller is driven directly by the motor (where a turbo's compressor impeller is driven by a second impeller in the exhaust). 

  • Typical Impeller Speed 140,000 rpm (160,000 max)

  • Internal speed multiplication is 12.7:1. This is accomplished with a state-of-the-art "traction drive" unit. It functions like an automatic car transmission using sun, planets and ring. There are no internal gears, belts or other types of mechanical connections. This eliminates the need for bearings or bushings running at well over 100,000 rpm (like a turbo).

  • Input speed to the blower is that 11,000 rpm well under the maximum rating of the belt. 

  • The stage I unit is capable of boost numbers of well over 10psi.

  • This unit carries a 2 year warranty for off road application. (The same unit when used On road has a 150,000 miles or 10 years warranty). 

  • Lubrication is accomplished with a highly special high grade type of transmission 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 MPI 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 sidecover is not modified. Simply remove the OEM fan assembly and bolt on out PTO assembly. It's that simple.

  • 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 (snowmobile belt drives are 60mm wide), our belt sports a safety factor 3-1/2 times higher than the industry accepted belt drive, since we are transmitting less than 20HP and belt drives transmit over 200HP.

• 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 Intercooler & Airbox are design and constructed entirely of aluminum and utilizes and intercooler core capable of supplying motors over 300HP. Pressure drop across the core is less than ½lb. Air intake temperatures are typically between 30 to 50 degrees above the ambient air temperature.

  • Connection to the OEM carb (or 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 Rhino employs an Automotive EFI style Fuel system.

  • Our system employs the same electric pump used on OEM Ford automobiles. Durability meets stringent ISO-9000 and automotive A-100 quality standards.

  • Power to the pump is electronically controlled. 

    • 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 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.

• Exhaust remains 100% stock. 

  • The system is compatible with all after market exhaust systems, but advertised horsepower numbers are achieved through stock exhaust. All dyno numbers and other advertised performance statistics were obtained through the OEM exhaust. TALK ABOUT A SLEEPER!!!

  • Be very careful with some aftermarket systems, we have tested several that actually loose HP (a lot!).

• 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 electronic temperature warning circuit that ties directly into the units  electrical system. In case of an overheat situation both a warning symbol and the check engine symbol illuminate in the OEM dash display.

• Blower and drive mounting.

  • Components are made of billet aluminum and connect 100% into existing bolt holes.

  • There are NO holes placed in any OEM component. Only 3/16" rivet holes and 1/4" mounting holes are added. No hole saws, no sawsalls just a 3/16" and 1/4" drill bit.
