This is beautiful. Hats off to you for innovation. I had the same idea for incorporating a intercooler into the Series II manifold somehow. You are making it a reality. Should work even better in real world testing I would bet. What heat exchanger are you using for that? Simply awesome! Can't wait to see it at WCBF08.

Jared, you MIGHT see two, the other being a S2 test car. Hopefully anyway, by WCBF. Although there won't be much to see by then. ![Laughing](https://www.gmforum.com/gm/images/smilies/icon_lol.gif)
Oddly enough, the inner core was selected primarily for size, as this method dictates fit over function. Luckily, I found a core that has some 'added technology' in the way the fluid circulates. You see it in the pics above, but what you don't see are inserts in the straight sections that force the water to swirl in a helical fashion, increasing thermal transfer on the outer surface of the feed tubes. I have the 180° fittings sweated off the end of one of them in order to slightly shorten the core (I always buy two of things like that when modification is necessary) and I'll try to get some pics showing this effect. Hayden manufactures them. No part number just yet, as I don't want to cut that information loose until I know it'* a good fit. Mine has to be shortened slightly to fit where it needs to, so I'll be cutting, flaring, and re-soldering. I have aluminum solder here already. In fact, I have my next LIM and that very core sitting right behind me at work right now. They're going to the machine shop at 4pm.
The beauty of the system is that it requires no modification to brackets or fuel rails. That'* a significant cost savings, particularly for the Series 1.

how much does this, or any ic hurt the air flow. doesnt it create turbulance? dont we usually mod to avoid this turbulance. or is the amount of heat dispursion more valuable than the air flow is restricts?

There is zero turbulence caused by the core. And the core was carefully selected, measured, and evaluated to insure that it allows for at least twice the cross-sectional flow area of the original SC triangular outlet, plus some margin. In my calculations, I assumed the round tubes to be an absolute restriction to airflow, which they are not. I also calculated the restriction of each and every fin edge.
Believe it or not.
Think of the inner chamber of the LIM as a static manifold that you only 'fill up' and slightly pressurize, to be a reserve for when a valve opens. It'* the runners leading to the cylinder heads that you want to be careful with in terms of flow and lack of turbulence.

so, are the fins, or "walls" of the LIM doubling as supports for the core? if so, does this make the walled intake the new, more desirable LIM?

No, the walled LIM is shown because it'* a worthless POS with a crack in a water passage, so I did a hack-job on it as the TEST LIM. I have the preferred non-walled manifold (identical to the two I have installed) here at work about to be neatly machined for the install.
The walls aren't for support. They're for acoustic damping, much like the resonators on your OEM intake. (you actually only have one, but the 94/95 had two)
