Those are some of the thoughts I had however.
The trumpets/velocity stacks makes sense, but does the GReddy system utilize this? Once the ITBs are all open it seems like it is functioning pretty much the same as a normal manifold just different runner lengths for shifting power band not really increasing.
Also If the stock system flows more then enough air already, would it matter if some cylinders had more access to air then others if none are still getting less then they utilize? Which seems to be the case if larger TBs and bigger manifolds haven’t shown any gains.
