Is there not an inherent advantage to a roller (either hydraulic or solid) that within a given lift, duration and overlap profile, the roller allows for a more aggressive (quicker) opening and closing of the valve via a more aggressive lobe profile than is possible with a flat tappet with the same specs? I was always under the assumtion that this was one of the biggest advantages of a roller over a flat tappet cam. Again, maybe I'm all wet here, but.......  |
