In an effort to continue to push the envelop on 4 stroke turbo snowmobiles,
Evolution Powersports is proud to announce that we have completed the fabrication and electronics for the first of a whole line of No Compromise Yamaha VIPER / ARCTIC CAT 7000 Turbo kits. The Arctic Cat version is called the BIG CHUTE 7000 TURBO.
The heart of any great turbo system is the turbo and fuel/boost management system. Our turbocharger is a TiAL/EVOPS Billet Wheel IHI Turbo which is capable of 400+ hp. These are the same turbos that are dominating the Arctic Cat 4 Stroke mountain and drag race markets throughout the US and Canada. This turbo, despite its high maximum power potential, lights up instantly. Our electronic package consists of an EVOPS spec altitude compensated boost/fuel controller that is light years ahead of the currently available options on the market. Our controller allows us to scale up the fuel injectors to allow more fuel without affecting the off boost fuel mapping. We also re curve the stock timing map to make it more boost friendly and lowering octane requirements. The timing re curve also removes the need to install a head shim at this power level.
There are a few items not shown - our fuel controller, water lines, clamps, etc. As stated earlier, the water lines and charge tubes will be made from custom molded silicone.
The intake has frogskinz on 3 sides (not on the top) as well as a filtered reed valve as part of this system that is further upstream which allows the engine to breath even if the entire intake was 100% covered in ice. We closed off the top to keep the engine from breathing the hot air coming off the radiator.
We prefer to engineer solutions that do not involve cutting factory plastic or altering the exterior in any noticeable way. For example, our heat exchanger for the water to air is a billet machined part that will bolt directly in place of the access panel below the engine. It will not require any modification to the belly pan. The oil filter is still accessible from the mag side of the engine.
All of the factory heat shields for the breather, etc remain in tact. The exhaust uses all factory mounting locations. The turbo hangs on a direct replacement horizontal spar that is made from chromoly rather than aluminum.
We will continue to push the envelop on 9000/1100T now that we have a handle on the drive line issues - MORE POWER and LOWER FUEL REQUIREMENTS - Stay tuned.
The kit also features:
• WATER TO AIR INTERCOOLING with BILLET machined heat exchanger
• LARGER FUEL PUMP
• COLD AIR INTAKE WITH REED VALVE BYPASS
• STAINLESS STEEL EXHAUST
• SIMPLE INSTALL
• 550 CC DROP IN REPLACEMENT INJECTORS
• NO TUNING REQUIRED
• CUSTOM SILICONE INTAKE, CHARGE TUBES AND WATER LINES
More details will be released in the coming days and weeks.
