If you have a .640 lift cam first of all you have to subtract lash and deflection so let’s say you have a .615 lift cam. How many times does a cam hit .615 each cycle. How many times does it hit .300, .400, .500 each cycle.

John, since a flow bench is just really for air flow improvement or correction and basic " tell what a head has for cfm", what kinda flow numbers do you think a bench would show if the camshaft lobe was involved, opening on its particular ramp, and at speed ?
Because I see guys on there flow bench running a particular lift for 10 seconds or longer, a valve isn't open at that particular lift for longer than, id guess way less than a second. I imagine the entire lobe -valve lift is done before .050 of a second ( wild *** guess)
Probably need some high speed cameras and other cool stuff to test like that. It seems that would be a more real world test.
Do you know or heard of anyone trying to test like this ?
