I thought it was strange that someone with so much dyno experience would make a blanket statement about an intake like that. There's so much that's combination dependant that you can't paint with that broad of a brush. I port matched my super victor to the victor heads as the intake was already smaller than the head. As that blanket statement indicates, I should have opened the intake up much larger. I would have liked to have been able to do extensive testing with this intake but I usually don't get R&D time on the dyno.
