Rush/RMK Aerocharger Kits
(913) 541-0200

The Rush/RMK Aerocharger Kit for the Polaris 600/800Rush and 800 RMK 800 are designed to be simple and fast. Using the stock expansion chamber, this kit can be installed easily and quickly, getting you back on the mountain enjoying your new turbo sled.

With a compact turbo and muffler package, no modification of the factory pipe is required. The turbo system is complete with a modular turbo/exhaust assembly, cold air intake, intercooler and air box. The muffler section is ceramic coated and header wrapped to keep underhood temps as low as possible. Together the entire turbo, intake and muffler section weigh less than the factory silencer by almost 3 lbs.

The kit features: 53 or 66 Series VATN Aerocharger, custom air/air intercooler, fuel pressure regulator, adjustable EFI control box, wide-band O2 sensor, boost, fuel pressure and air/fuel ratio gauges and a high flow fresh air intake, along with some optional components.


Ski-Doo Turbo System
(913) 541-0200

There is also an Aerocharger turbo for Rev XP E-Tec 600/800 and Summit E-Tec 600/800 sleds. The design behind the layout of the Aerocharger turbo system is centered on efficiency and responsiveness. The turbo sits low on the chassis to provide the most straight exhaust section as possible before entering the turbo, which allows for quick spool-ups and great response. The muffler section is also as straight as possible for optimum evacuation of exhaust out of the turbo. Other turbo kits may try to cram the exhaust through 90-degree bends in and out of the turbo, but Aerocharger works to keep efficiency in mind and they say the result is the quickest spool and best response.

Key features of the system include: 53 or 66 Series VATN Aerocharger, custom air/air intercooler, custom air box with fuel rail and secondary injectors, ceramic coated muffler, fuel pressure regulator, adjustable EFI control box, wide-band O2 sensor, boost, fuel pressure and air/fuel ratio gauges in a custom gauge housing, as well as optional components.

Yamaha Nytro Supercharger
(888) 649-4609

Mountain Performance's supercharger is a pump gas, bolt-on upgrade for the Yamaha Nytro and gives you an instant 180 hp, regardless of whether you are operating at sea level or at 10,000 feet.

At sea level, the kit operates at 4-5 lbs. of boost and adds approximately 45 hp to the Nytro's stock 135 hp. At high altitude, the boost is turned up (5-6 psi for 3,000-6000 feet and 6-7 psi above 7,000 feet). By varying the boost level at different altitudes, the horsepower remains at a consistent 180 hp. Mountain Performance can custom-tailor the kit to the altitude you ride. All this is accomplished with a stock unmodified motor on pump premium fuel.

The kit is based on MPI's Stage 1 kit, but it has a smaller supercharger. At only 4 percent smaller than the Stage 1, the new supercharger delivers nearly as much boost: 14 psi maximum sea level boost versus 15 psi for the Stage 1. The kit is not intercooled, making it an easier, more affordable install. The kit comes with everything from "soup to nuts" to complete your install, along with a billet blow-off valve. The kit can be retrofitted into a Stage 1 with the addition of an intercooler and upgraded electronics. For riders looking for power from the Nytro, MPI also offers Stage 1, 2 and 3 supercharger kits. Application is for 2008-2011 Nytro models and variants and retail price is $3,995.


Yamaha Nytro Stage 3 Supercharger
(888) 649-4609

This is a race gas kit that Mountain Performance claims is not for the faint of heart. It uses the new C30-94 supercharger and additional motor modifications to create "freakish" horsepower. At sea level, the kit is designed to produce 30 lbs. of boost making 430 hp. At 10,000-foot altitudes the kit produces more than 20 lbs., making more than 330 hp.

This kit uses the same compressor that has been used for the last five years on the company's automotive kits for BMWs, Jeeps, V6 Mustangs and others.

The kit includes the new Fuel-Pro stand-alone fuel system, replacing the factory computer for fuel injection. It automatically compensates for altitude, boost, water, ambient air and boost air temperatures. A closed loop version is available that runs off of your ProLogger or other ARF gauge (not included).

The kit requires motor modifications to pistons, cam gears and head studs (sold separately). New rods are also recommended, but at a minimum, new rod bolts are required. It includes the complete supercharger system, billet MPI blow-off valve, cold air intake, Fuel-Pro fuel system with 750cc injectors, fuel pump and returning regulator system. The kit is for 2008-2011Nytro models and variants and retail price is $6,995.


Arctic Cat Tial Pump/Race Gas Turbo Kits
(801) 940-7777

By using a Tial external wastegate and Tial turbine housing, Ogden Valley Sports has developed a turbo system that is more powerful, faster spooling and has lightning fast throttle response. The OVS Tial turbo system is user-friendly for the consumer when it comes to tuning and using pump gas or high boost race gas.

The Tial turbo system includes new components like an o-ring fit billet air plenum. The centered and tapered inlet design of the air plenum allows for smooth, equal distribution of air to both cylinders. The air plenum retaining system keeps the air plenum o-rings sealed tight to the throttle bodies and also holds the throttle bodies tight into the reed boots without attaching to the chassis. The plenum retaining system allows for engine vibration without causing damage to the o-rings in the air plenum and will not allow the throttle bodies to be blown out at high boost levels.

The exhaust clamping system is another industry first component that allows easy removal and installation of the tuner pipe. This clamp system seals tighter than using multiple factory exhaust springs that have a high mortality rate in boosted applications.

The OVS E-link was developed for the easy install of the Tial external 38 mm wastegate without having to cut and weld a 38 mm pipe into the stinger of the tuner pipe. Cutting a 38 mm hole into the stinger of the tuner pipe causes the tuner pipe to perform inconsistent when the wastegate opens. The E-link is ported and back-bored inside the housing the same way that a turbo chargers compressor housing is ported and back-bored. This allows exhaust to flow freely to the turbine wheel and not affect tuner pipe performance when the wastegate opens.

The OVS Tial turbo system has a unique feature in the wastegate housing that allows the customer to adjust boost without a boost controller. This feature was developed because boost controllers cause boost spike while trying to trick the wastegate into changing the boost levels, which causes a rich fueling condition and inconsistent tuning for the consumer.

The newest component in the Tial turbo system is the billet throttle body manifold that is o-ring fitted to the throttle bodies and also houses the secondary injectors. This component eliminates the need for dual-injected throttle bodies that have to be assembled and the TPS reset, and with it, no one has to send stock throttle bodies for cutting or make modifications for secondary injectors. The billet throttle body manifold allows the secondary injectors to inject fuel directly into the reed cages. The billet manifold also solves the problem of rubber boots that split and break.

The Tial turbo kit includes: Garrett dual ball bearing turbo charger with compressor housing, Tial stainless steel turbine housing, Tial 38 mm wastegate, OVS E-link system, OVS boost adjustment housing, turbo muffler, 2.5-inch mandrel-bent charge tube, billet o-ring fitted air plenum, air plenum fastening system, billet throttle body manifold, oil tank and oil/fuel pump with fuel regulator, in-tank fuel pump bypass kit, fuel pressure gauge, in-house fuel tuning with the Pure Logic control box, secondary injectors, boost gauge, AEM 02 gauge, gauge pods, primary and secondary clutching, blow-off valve, charge tube, stinger pipe with graph oil gasket, plug and play wiring harness for gauges and oil pump, fuel line assembly, air filter with outerwear, turbo vent kit and all necessary hardware to install the turbo system. The system can be used with or without the factory oil injection system.

After the success of its Yamaha Nytro 180 hp kit, MC Xpress tested a stock compression turbo on the Ski-Doo 1200 with excellent results. The kit has simple installation, comes complete and requires no adjustments. The air-fuel ratio is right at any altitude and power is maintained at higher altitudes. With a stock muffler, the noise level is low.

Many people have been waiting on a competitive 4-stroke engine from BRP and many want to convert it to a reliable, fuel-efficient, quiet muscle sled to compete with Yamaha turbos.

Prince George offers a number of turbo kits, including two for the Yamaha Apex. One version is a 200 hp kit with stock compression ratio for fast installation and the other kit will deliver about 300 hp. The 200 and 300 hp kits are Dyno-tested as well as in the field. The EXUP valve in the exhaust system is left untouched and the noise level is surprisingly low.

The 4-1 system on this machine makes the exhaust sound very attractive. Compared to the MCX Nytro turbo, this machine is quieter.

Turbo Accessories

ProLogger Gauge, Boost Controller Package
(888) 649-4609

ProLogger is an all-in-one gauge, data logger and boost controller in one small package. It was developed for boosted sleds, but aspirated sleds will also benefit. It has four buttons (power, menu and up/down). The readout is in English and easy setup manuals are included. No computer interface is required for programming or data review.

The gauge portion includes ARF wide band (never requires calibration), a tach and a vacuum/boost gauge. You pick two features from any two of the following options: temperature gauge No. 1, temperature gauge No. 2, boost controller (electronically controls your boost), 1-3 stages of NOS control and water or methanol injection. The temp gauges have warning limits that flash regardless of any other display setting.

The data logger records 10 sessions up to 99 seconds long. It's easy to start and review your data. It logs exactly what you need to tune your sled: rpm, air fuel ratio and boost. It works on any snowmobile model and retail price is $695.


Electronic Booster Controller
(208) 542-4411

The Electronic Booster Controller features the fastest spool-up possible through advanced electronic wastegate control. Its simple design allows you to pick a desired boost number and maintain it. It has altitude compensation and it auto adjusts boost to changing atmospheric pressures, maintaining consistent levels.

Push to Pass, a remote push button, builds an instantaneous blast of boost. It comes in a bright visible LED boost and altimeter gauge in a silicone-filled, water-tight package that will enhance any turbo system.


Adjustable Actuator
(208) 542-4411

This actuator allows you to get lower boost minimums and higher boost efficiency without changing actuators. The Adjustable Actuator has an operating range from four psi and up. One simple adjustment makes it ideal for changing from pump gas to race gas at lower elevations to high elevations. It works on all internal wastegate turbos.


Nytro Extreme Tunnel Coolers/Heat Exchangers
(888) 649-4609

The OEM Nytro cooling system is often inadequate for the higher cooling demands of high horsepower supercharged and turbo charged snowmobiles. These tunnel coolers were designed to work with even the largest tracks without modification to the tunnel's appearance. This kit can be used with or without the OEM radiator, making it possible to shed more weight from the snowmobile while still enhancing the overall cooling system. This is no little cooler. The actual extrusion measures just over 8 feet long compared to the OEM tunnel cooler that isn't even 2 feet long.

Cooling performance improvements means greater horsepower and reliability. Operating temperatures 60 degrees cooler are typical from this tunnel cooler and the OE radiator. You will run 40 degrees cooler running the cooler only when you eliminate the OE radiator and tunnel cooler. Hoses, clamps, rivets are included.

A radiator delete kit is available separately and it comes with a degas bottle to help keep air out of the system and provide a location for filling. It uses the OE Yamaha radiator cap. It is applicable to the 2008-2011 Nytro XTX or Mountain model and retails for $465.
