So the method you describe is the centerline method, the method I am using is the duration at .050” lift.
Wouldn’t it be easier/more accurate to do the duration at .050 since you would be able to see when the cam hits and leaves the .050” mark easier as opposed to the centerline method where it could be at max lift for more than 2 degrees of rotation?
The videos I have seen (like the one you posted) really don’t go into where to find the centerline of the lobe. Just that it’s at max lift, but they don’t address how it’s at max lift for more than one degree. And being that it is at max lift for more than one degree, I don’t see how you can find the true centerline. Unless I am missing something?
