Well this is an interesting point. I makes you wonder if the entire time Cyclone knew that their engines did not work and this is why they never really got any reliable diagnostic equipment. Honestly, I cannot remember seeing in any of the videos a reading of an actual output from any Cyclone engine. Much of the time they show RPMs, or pressures or temperatures.
Does anyone know if they ever showed any real dyno data or anything of the sort? Has any video ever shown any useful numbers? If not, I call shenanigans on Cyclone. They knew that they were making paperweights the whole time and I dare Frank or Mark or whatever the name she is using this week to prove me wrong.
