Anyone done any back to back testing on the stock intakes? Flow bench, drgastrip or actual dyno testing? I am curious what would be the best ones if hood clearance and such are not an issue, does the flat runners on the front of an SRT 6.4 intake make less power than a truck intake with straighter butt longer runners? Does a ported 6.1 flow as much and I know they run a lot hotter, how much does heat soak affect it? I know the eagle intake is pretty good but it is sharper curves and smaller port size, just how good/bad is it compared to the different 6.4 intakes?
