Below is our pump cam compared to the OEM 160hp cam
Below that is an older 3406 cam a c-15 a c-18 800hp cam and a c-18 1000hp cam.... Notice that they are slower, but they have a rocker ratio to amplify the injector motion where the P-7100 is direct acting meaning it runs 1:1. If memory serves me correct the 3406 has a 1.69:1 amplification which makes it a good bit faster than the p-7100
Below is a graph with the C-18 800hp injector lobe with the rocker ratio factored in. There are two pink lines. The top is after rocker ratio and the first is before rocker ratio. It is a good bit faster than the p-7100.
Below is an p-8600 with a hot grind. It is a good bit faster than the c-18 cam
