Camshaft #2 has excellent top-end horsepower. 12 mm (calculate h when A = 1335 mm ²), the K-cam in my B20 engine will lift the valves an extra 0. For example, if the camshaft lift is 0. of force Jun 10, 2020 · The Rocker Math Calculator has determined that increasing the lash by only 0. 050 inches, the duration is measured from that point. All lift figures in this catalogue refer to valve lift. Textbooks tend to give examples quoting the camshaft speed—reasonable as the textbooks generally are considering only the cam and follower, not their possible inclusion as part of a four-stroke engine. 543" lift, 238° duration, timing 15/43. If you're a racer, race enthusiast, or engine builder with engineering talent, for info on joining our team. Once you have collected lift measurements at various points in the engine’s rotation, calculate the peak lift of the camshaft. What is the theoretical lift? A cam lobe has a nose radius of 4 mm and a total lobe width of 240°.
