I wanted to add this since my previous post sounded like I did not want to teach how to design a cam profile. I just do not think I have the ability to do so. Each camshaft application has its own limitations on cam profiles. I am certainly not an expert on every application (not even one). That comes from years of experience working with each particular application. You learn from trial and error on how far you can push the limitations. It is difficult to teach that especially if you do not know the limitations. Limitations tend to also change as valve train materials become lighter and stronger.
I have no problem sharing knowledge. That is why I write these posts. If you are someone that has a cam design program and has a specific question, I will be glad to answer it if I can. Trying to learn about cam design without actually doing it is difficult to do. Sort of like learning to ride a motorcycle without actually riding it. There is much to learn about cam profiles without knowing how to design one. That is what I really try to do here on Cam Talk.
