Anyway, that IM design is junk. That's innovative placement of the velocity stacks to keep flow from disrupting the adjacent stacks, but each one is shrouded by the side of the IM it is angled toward.
Vizard published practically everything he deduced about flow (and other aspects) 40 years ago and did so in a manner that could be understood easily by your average intelligent gearhead. Never read the first issue of Hotrod, huh, or taken a non-primadonna attitude to applied theory and design aka reading up on what your betters did before you?
