I like the idea of evolving to a 4-stroke with CVT, as suggested by Bobby J and others. Without the CVT based snowmobile drive train, as others have pointed out, our class becomes redundant with other formula cars. But a 4-stroke would need more displacement, hence probably more cylinders to make the same power. For example, "In 2001, Arctic Cat had the first modern 4-stroke sled on the market. Essentially, it's a Pantera 2-stroke touring model fitted with a 4- stroke, 658cc, liquid-cooled, fuel-injected 3-cylinder. Thanks to intake and exhaust improvements, it's rated at 53 hp for 2003, a 17 percent increase. More recently, from Yamaha "The new RX-1 snowmobile is powered by the same 4-stroke, 998cc, 4-cylinder, DOHC, 5-valves- per-cylinder, liquid-cooled Genesis Extreme engine that powers the award-winning Yamaha YZF-R1 sportbike. The biggest difference is that the motorcycle engine is now fuel-injected and develops 152 hp at 10,500 rpm, while the snowmobile version uses four Mikuni BSR37 carburetors for a peak of 145 hp at 8300 rpm."
Has anyone explored whether any current 4-stoke snowmobile engines of comparable power to our current engines would fit in our cars without major mods?
