Eric's cam challenge

1MeanA said

I don't see how lift at 0.006" is meaningful at all not that one number tells you all about the cam. I think Crane had something with the 0.050" lift thing. It seems to be working well as a comparison measure does it not?

Think in terms of pressure differential between the manifold side of the valve compared to the piston side of the valve.

.006 lift changes the pressure differential above and below the valve.

You calculate that as time/area. IIRC the .006 lift point is for hydraulic lifters.

For solid lifters it should be the lash point.
