I wonder if a wedge could be built on top of the vw Weber manifold to elevate it a little and funnel the charge into the 2barrel plenum. It would boost plenum size. Probably have to be done neatly to ensure no hard edges where fuel could condense. I would like to see a little more downslope of the runners from the manifold to the elbows also. Dan's mod seems to be the only one with it. I was looking at a few Porsche manifolds and noticed some of the better performing models on flat sixes had more downslope and about 120 degree elbows instead of the near 90 degree elbows we have. The 1200 had more angle to the elbows.</p></blockquote><p></p>
