the mca,,,,, will effect the ports pressure on the cylinder during filling in the compression stroke,,, when you have a port that flows extremely well,, its obvious the filling in the intake stroke will be enhanced,, therefore when the piston starts comming up, compressing that mixture there will be more charge in the cylinder, causing more pressure,, the point at which the pressure of that compressed mixture becomes equal to that of the inertia pressure in the intake runner becomes equal,, you must close the valve,, inertia increases as engine speeds comes up, or gets higher to the point that the mca restricts it, causing it to stall, and not produce anymore,, therefore anything past that speed will push charge back into the runner if the valve is open longer, loosing power

its not that "I" cant get your numbers,, nobody on the planet,, but you,,, can,,,im not saying they arent true,, id just like to see you validate them with somebody else,, its not like you got 440 out of them,, which would be a high number,, but maybe possible,, you got 470,, that number is so high,, higher than anybody has heard, got,, etc...
