but if i was gonna state something it be the dyno test was biased to the low rpm duel plan and never turned enuff rpm for the single plan intakes to get into there sweet spot! now dose this prove anything, no!! its just one lowly rednecks opinion. now redo the test, put a proper cam that matches each intake and let it run to peak hp and see how that turns out! the best engine gonna be built from parts that work with each other not mixed matched....DWB!
