Free nasty cams
This is especially true for Two-Valve modular motors.
As a general rule, the closer to stock the remainder of the components, the milder the cam profiles that should be chosen.
The chore of improving the head flow of the stock PI heads was given to the flow experts at Total Engine Airflow.
They increased the flow rate of the PI heads significantly, allowing us to take full advantage of the larger cam profiles.
Many mod-motor enthusiasts at least understand the basics of cam timing.
They realize that cam profiles come in a variety of different sizes.
Our test motor was a modified 4.6L Two-Valve combination that represented what might be found under the hood of a mildly modified (normally aspirated) '96-'04 Mustang GT.
From an anatomical standpoint, the camshaft can be likened to the brain, as the profile determines how effectively (when and where) breathing takes place.Technologii Flash ve svém prohlížeči povolíte stisknutím „přepínače“.Flash můžete také zprovoznit stisknutím ikony ve tvaru dílku skládačky puzzle v pravém horním rohu prohlížeče.Topping off the modified GT motor was a rather stock PI intake manifold.
Though many aftermarket intakes are now available for the Two-Valve motor, we chose the PI intake.This means leave those weekend-warrior cams to the drag racers with lots of gear, aftermarket heads, and free-flowing exhaust.
