Anthony, I would have to disagree with the redundancy theory... The cars are smaller, more simplistic, and cheaper, regardless of the power plant.. A CVT makes them the only road racing class in the world with that type of drivetrain. Wonder why it hasn't caught on...... CR

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?
