It seems that the premise on this engine has been misunderstood. "But the OX2 engine fires all eight cylinders TWICE in only ONE revolution." "This means that the pistons have to travel back and forth at a furious rate equivalent to a motorcycle engine turning 10,000 RPM." First, the premise that the pistons are independent of each other is wrong. If the engine is running at 3000 RPM the internal RPM is 6,000. There is no reason for this engine to turn more than 3,000 RPM and is not designed to run more than that. The statement above would mean that the engine would have to running at 5,000 RPM. In most application for internal combustion engines today more than 3000 RPM is is not needed. Boat screws and airplane props cavitate at around 2800 to 3000 RPM. Current engine today rev at 5800 - 6000 RPM and then use transmissions to obtain a 2-1 ratio. Why not have an engine that revs at 3000 RPM on a 1-1 basis. The engine would apply all the torque and HP at the 3000 RPM. Current engines today loss 25% of its torque and HP at its redline and that is why they call it torque and HP "curve". Usually at 4000-4500 RPM a coventional engine is at its full torque and horsepower and looses it as the RPM increases. "The mean piston speed for the 75 millimeter stroke is ABOVE what is considered acceptable for racing use. The pistons have to travel 4905 feet per minute." "Racing dictates that piston speed be kept below 4500 feet per minute." These computations are based on the premise that the pistons are independant of each other. The numbers are wrong and need to be reconfigured. "The OX2 dyno charts have a few readings, and a straight line is projected on the graph to indicate that horsepower will keep on climbing past 2500 RPM." "This is ridiculous, because the engine is running past reasonable limits when it is turning 2500. It will probably never reach 3000 RPM without destroying itself." Comparing the two engines was to show that between 1000-3000 RPM the OX2 produces more HP and Torque than a 350 V8. There are no publicly available charts on a 350 that start below 1000 RPM because that is where it idles. The OX2 idles at 200 RPM. No comparison points. The OX2 in it's current configuration is designed to run at 3000 RPM and that is as far as the comparison could go for a 350 v8. Here's to civility!!
