Editing User talk:Therightcurve

40 years ago, my father told me of a genius named Ed Winfield that designed and ground his cams.  Every camshaft Ed ground for my father made peak HP occur at the RPM he requested, no matter how different the bore, stroke, rod and RPM combination was on these engines.  My father told me, though nobody had ever seen it, Ed wrote an equation in 1955, that calculated the requirements for valve seat duration and net valve lift, with the piston motion, or rod to stroke ratio, determining the curve.  Back then, it seemed nobody wanted to believe it, especially the magic peddler's or cam designer/manufacturer/grinder experts.

Now, here we're approaching 2016 and I'm hearing the same thing from every camshaft expert today.  The articles and books on selecting the correct camshaft tells you that the longer the duration the more RPM, and the more lift, up to some point, will get more air in the cylinder.  There is never any mention of how to quantify any of these values.  Do they know, but don't want to tell?

So, how big a deal would it be, if someone wrote out the equation on this forum.  Do people really want there to be an equation, or do they like the mystery and magic?
