The guage has a problem in that it is too accurate and does not read high enought for the kinds of vacuums you can expect. It does how ever have two inputs, a low and a high so it is possiable to put test point on either side of the restriction being test. In this way it ignores atmosphere.
I plan to drill in test points at various locations along the intake so as I can measure the restriction at each step.
From my reading it seems that any gain on the intake can be quickly lost if you don't improve the exhaust. I tend to think the intake on the SVX will be a problem as we have a Liberty 2.2l and it has the same airbox & filter.
