Ford Modular Engines - Follow The Leader - Tech
This is a dyno graph comparison of Jesel cam followers versus OEM ones. The Jesel components were far superior to the factory pieces, as you can tell from the graph. This supercharged engine picked up power from the start of the pull until the end. Peak rear-wheel horsepower shot up by 50, while torque saw a gain of 33 rwtq. These results were impressive, and the Jesel cam followers prevented valve float in the upper-rpm ranges. The valvesprings on this engine were never designed for big rpm or 20 psi of boost, but they worked fine with the addition of the Jesel parts. View Related Article
