Yes, there is and has been an equation that calculates an engine's camshaft requirement, with an accuracy of +/- 1%. You may not believe it, but it is true and it doesn't require a college degree to understand. It was written in 1977 by, the late, Dick Jones, former Technical Racing Manager for Champion Spark Plug Company, in charge of their West Coast Engine Dyno Facility. His formulas have been used by many of the industries premiere engine builders, aftermarket parts manufacturers and two or three cam companies. The math has been qualified as a true equation by two separate college professors, and verified by an automotive engineer with a PhD in Fluid Mechanics/Dynamics. | Yes, there is and has been an equation that calculates an engine's camshaft requirement, with an accuracy of +/- 1%.

| − | The Jones Equation calculates the valve opening lift curve, required by the effective port area, to fill the given cylinder the desired V.E.%, at the requested RPM. | + | The Jones Equation is built on, and describes, the mathematical relationships of the engine parameters, operating variables and performance. The equation can solve for, or be solved by, any of the related parameters, including the camshaft. The Jones Equation calculates the valve opening lift curve, required by the effective port area, to fill the given cylinder the desired V.E.%, at the requested RPM. |

| + | Rick Jones says he will guarantee the software's accuracy, with a full money back offer. And Rick stated that there is no story to go along with a video or charts on a overhead projector. This calculates the required valve motion to fill the cylinder and generates the curve, then displays the total calculated cam configuration, as fast as you can enter the values. It is an equation. It doesn't matter the size .7854 ci at 30,000 rpm....not a problem. | ||
