hapisok is correct. On a traditional carb or port injected application increasing plenum volumne/area can result in increased power in the upper RPM ranges, but this is an unknown until it is tested on the DI 3.6 as these engines are so dependant on velocity for the power. CFM flow #'s that we used to follow so close have to be balanced with velocity and volumetric efficiency on these motrs so much of what we have used as far as the science & technology of the past cannot be followed on these. I am anxious to see how they will work and it may be a hit. We'll see what Mace finds.
