Cool, thanks DR. I actually thought that might be the case because once I saw the Blackbird design (which I like a lot) I started looking around for similar in-line filters/canisters and couldn't find them. Since I have an '85 the Blackbird won't work for me, so I thought of working out my own solution.
Eagerly awaiting the time when production catches up with brilliant innovation.

That makes 2 of us !!!

This is probably obvious to most.... but...
Does DR's two TB setup require two MAF sensors?
If not, where is it located?
I would be interested to see a picture of what is under DR's shiny cover behind the autorotor pump.... if that's not inappropriate...

It looks like two MAFs are in place, but really only one is used. The other (pass-side) is a non-functional dummy. This way we don't run into the 5v limitation of the MAF as only 1/2 of the air flow is getting measured. We are able to "trick" the car via the SharkTuner.
Here's a pic of Tom Falkenberg's car, BWARNEY!

[QUOTE=DR;4485375]For the 85/86 32V I would take a close look at what John Kuhn has done for filters on his S4 Twin Turbo. He told me he would be interested in selling his air filter adapters separately and they would solve the side intake clearance issues of the 85/86 32V and give you the option of twin aftermarket filters.QUOTE]
He told me the same thing and when I inquired about pricing he asked me how much I wanted to pay. Not wanting to offend by offering $1.00 including shipping/handling I asked him to come with a price. Still waiting for his response (the email before last SITM).

Can you point to pictures of John's filter(s)?

I had thought about relocating Andy's single TB to much the same location at the plenum.
Are those OEM 928 TB's? Is there any functionality from the OEM TB's that has to be retained.... like vacuum ports? I don't see anything, but then I don't really understand the character of the vacuum signaling needed for the fuel regulator and dampers.

Just so it is clear, I was discussing the "Air Guide" not the intake manifold. The Air Guide is the part that the throttle bodys bolt to and that bolts to the intake port of the SC.
To answer your question the cast part I have designed should be able to be CNC'd to fit the Eaton also. If someone could send me a template of the intake port surface on the Eaton I could confirm this when I get the time.

Bill, whose car is that? Do you know where the got that through-the-cowling ovalized plastic ducting?

Brian: John Speake provided the link to John Kuhn's thread on the intake in the post prior to mine. I can't tell if those very nice plastic tubes were fabricated or adapted from a off-the-shelf part. They are the missing link. It looks like John strived to maintain the same cross sectional area with very wide ovals. If your aerospace engineer son is right, and I will guess he is, then a smaller piece that would fit through the existing oval in the fan shroud would be just as effective. I can tell you the Vortech's are affected a lot by upstream intake cross-section, but, of course, they aren't positive displacement.

Brian, I was going to use that design and met John at SITM to check it out. The problem was that I only needed the right side and with that small filter, you need both sides tied in to get the right amount of air. It did look sweet, but just didn't work for me.
Bill, John fabricates those snouts from scratch, he did a hell of a job in my opinion

Not THAT is exactly what I've been trying to figure out, except that I was only going to use the right side for my SuperModel installation. My newly minted aerospace engineer son has opined that even one of the stock induction openings in that radiator top-cowl would feel the engine because it is a positive displacement pump and it will suck what it needs through almost any sized hole. Yes it can create a substantial low pressure area ahead of itself this way, but apparently that is immaterial, provided it doesn't collapse the ducting in the process.
