This is from movingsnow.com: Here is a simple chart of approximate cc to torque to horsepower conversions. It's not exact, but it will give you a better idea of how big the new engines are. I used 3600 rpm in the formula for this comparison. 179 cc = 5 hp 205 cc = 8 to 9 Gross Torque = 5.5 to 6 hp 250 cc = 11 to 11.5 Gross Torque = 7 to 8 hp 305 cc = 13.5 to 14.5 Gross Torque = 9 to 10 hp 342 cc = 15.5 to 16.5 Gross Torque = 11 to 12 hp
Torque
