EFI Filter Air Flow Calc?

[jetenginedoctor]

Although it doesn't "look" as cool as individual filter elements for each inlet horn, a larger single element will provide far better performance benefits. Consider the fact that no two cylinders are filling at the same rate at the same time. Allowing cylinders to breath through a larger filter element that serves multiple cylinders means that the resulting depression across the filter is smaller and has of a "secondary throttle plate" effect on the engine. We've removed pod style air filter elements on several engines and replaced them with an airbox equipped with a panel filter element or circular/oval element and have seen dramatic improvements in top end horsepower, not to mention the fact that the throttle bodies are a lot easier to sync that way.

Your milage may vary. . . . but I doubt it.
