Yipes! Sure don't like that "pucker" effect!
But now I'm a bit confused. Your tests showed that the stock setup provided ALL the airflow, and then some, that the engine needed at 5500 RPM? More than 473 cfm CANNOT add to power? I can accept this, if the 473 max is correct - in fact, there's no way the engine would take in more than this amount, right?
But, it appears from Bill's dyno testing of an 09, that there IS an HP boost with the snorkel removed, suggesting that the engine IS capable of "sucking" in more air than is available in the stock configuration and mixing more fuel with it - resulting in a bigger "bang".
So, I'm left wondering what is causing the inconsistency. You measured airflow. Bill measured HP. I'd like whatever gives me more miles per gallon of gas.
