Rara-
So you don't think something like a custom advance curve and A/F tuning on a modded car will alter the optimum IMRC opening point then?
What about the many different lower intake diameters used? Still no change?
Fair enough... (still going to test it of course

)
What are your thoughts on total removal of the secondaries then? Only 3L or Forced Induction or not at all?
