No. You need more air to burn more fuel to make power. Elevation kills the air side, and you just can't get around that.
A very durable 5000 mile turbo 2t mountain sled with a good cooler and short tunnel would be perfect. How does burdant cut 40-50 lbs off a new sled? Surely they can cut out another 15lbs to make up for the turbo. The very nature of the turbo helps to quiet the exhaust, so they should be able to cut a few lbs out of the can to help with the turbo weight.
What did I find researching what sled to buy? Avoid the RMK because it needs rebuilt often, avoid the M because it's heavy, avoid ski-doo because it's heavy. All mountain sleds suck and overheat.
Boost by elevation/air density and 180-200hp from 0-12000ft would be perfect. Always consistent. Always predictable.
Don't make it a standard, but make it a snowcheck option. Big bores have been done to death. Ever wonder why there are no real big bore kits anymore and everything is boost now? It's cheap, effective, and retains parts availability.
My views may be skewed by the fact that I live at 4000ft. I ride at 6000'+. I've never seen a need for a low elevation setup because I don't know why you'd buy a mountain sled to ride in MN.
