What many different intake diameters?
The stock duratec lower, the early SVT, the late SVT/3L, an enlarged late SVT/3L...
That's 4 different sizes currently available. All significantly effect airflow into the engine respectively.
Just make sure your tests are not compromised by uncomparable methods
Would all be same day dyno testing. That would be a fairly accurate static test (I.E. not real world)
But like I said. I like them pinned the best & that's not even getting the high rpm benefits... We be nice if the dyno says the same as the real world does...
