The difference between the engines is a factor of 4!!!! You made the mistake of using a factor of 4 on the OX2, then you divided the 350 by 2. THIS IS THEN A FACTOR OF 8 !!!! Speed of engine parts is a direct calculation.. in the OX2, if the stroke is approximately 3 inches, then 4 strokes twice per revolution is piston travel of 24 inches. At 2500 rpm, then the piston average speed is 24 x 2500 = 60000 inches per second, divide by 12 and we have 5000 feet per second ( if you use the 74 mm stroke, then it probably is 4905 ft per sec) It does not matter what an equivalent engine's rpm is, just stick to the speed of the parts in the OX2!! To use the OX2 in a car it would not be necessary to change the transmission,, just change the gears in the axle.. Most vehicles have several ratios available.. also if you try a truck, over size tires also can greatly change the ratio. Did someone mention a rumor that a truck was given to Shelby to try, could this be the reason??? Trucks usually have more choices of rear axle ratios and tire sizes available. All the best ---John
