Howintheheck(tm) do you test that?  Temp sensors on various points of
the outside of IC?  Put your hand on it?  Straight test data, total
input/total output? (pressure loss, cooling, etc...).  If your IC (vert
or otherwise) has great efficiency and great pressure loss, how can you
deduce that the flow isn't evenly spread?  I'm serious.  I believe you
guys, but how do/did you figure this out?  Trial and error?  I mean you
are introducing another flow impediment (vanes), so pressure loss goes
up.(?)  I'd think bigger end tanks canted at a proper angle would be
much more efficient (ala the RayT link).  This is what Spearco did, and
he had flow benches.  Just talking out loud here.  This isn't a
challenge, I'm really curious...

IMHBBO (IMHBellyButtonO), the RayT bumper solution really reduces this
issue to a nit, as you can easily run a 21 x 6 x 3 (as he has done), or
converting that to horizontal, something VERY similar to your IC, with
at least a 12 in high core.  Either is more than adequate for +500 hp.

I'm dying to see the CO boys IC test results, see how
accurate/inaccurate MY belly button is.  :^)
