Well Said Mr Kesteb!

Your ground rules may be fine for what you are trying to accomplish, but giving up the tapered runners is not something I wish to do.



16 gauge steel tubing is exactly what I proposed.



1.5" 16ga tubing has only 1.47 square inches of internal area. The stock intake port is 1.68" square. I would suggest 1.625" tubing which has an internal area of 1.75" square. I planned on a 3.5" plenum to get the required volume in a shorter length. I also plan on using a divided plenum for reasons stated earlier.



I was not planning on using straight runners on cylinders 1, 3, 4 or 6. Those runners will curve or angle towards the center of their respective plenum. Throttle bodies go on top for clearance.



My '67 appears to allow longer runner lengths. As I pointed out power brakes (which I don't even have) would be out. Everything else looks fine.



Be very careful saying what can't be done. Mythical the Hyper-Pak is not. I'm not going to use J-tubes because I'm not going to give up the extra torque of a tapered runner. I can fit my design under the hood of my car.



Yes there is theory, next to no speculation, and it will fit under my hood. Until my manifold exists I don't think there is much more to say.

Ultimate EFI intake? Not professional, nor aluminum, but its will work. How good is anyones guess. Runners are equal length 1 1/2 X 14.3 utilizing the 3rd sonic wave of a 240 degrees stock 6 cam. The plenum volume is 225 CID (not planned but I can alter it with a spacer) and the injectors are going to be mounted 45 degrees off the flanges. Contrary to a few postings, the end runners usually get the most air as the air is like a fluid. It hits the wall and sort of stalls there, but being a dry intake, the air can take corners much better than a wet intake whos fuel drops out of suspension around tight turns. This "U turn" design is common to many intakes, ie 5.0, Mitsubishi and Hyundai.The "stacks" will be 1/8 radiused with a high temp 2 part epoxy putty around the top rim so as to assist in the air entry, and the 2 part epoxy will be rolled into a fillet and smoothed over the tube welds to ensure no vacuum leaks as well as hide the crappy flux welds of mine. Trying to funnel these runner ends or make velocity stacks was originally planned but the material was not available in the OD of the runners, 1 1/2 EMT. Cheap and plentiful, but it is galvanized on the outside so if you weld on it, grind the surface shiny and remove the electro-coated galvanization. The TB will come off a 90 toward the valve cover and then toward the radiator so the TB will face forward. This makes the rear pull Windstar TB in the correct orientation and makes the air cleaner ram tube/turbo plumbing that much easier. It weighs a ton but I cant weld AL so this is it. I was considering using PVC off an AL flange with high temp hose connectors but reconsidered when the un-intercooled turbocharger outlet temperature was factored in.
I got about $40 in parts not including the cast AL Edelbrock V8 valve cover Im using as a plenum! Its gonna look kinda strange but it was a perfect fit as I needed a bolt on cover so I could work on the runner ends. Stay tuned.....

There was actually talk at the Slant banquet of an application specific EFI intake being cast for the Slant. It will incorporate the TB at the front facing forward with the plenum parallel to the head. As soon as its drawn up and pattern work completed, testing will begin to evaluate is performance before being put into production. This design has already been used and tested on many other inline engines with great success, so it should be interesting to see how the Slant reacts to one.

There's no such thing as too much cam....only not enough engine!

One thing comes to mind with the end mounted TB. There is very little room! You will have to route the cold air intake plenum at a sharp 90 or youll have to route it over the radiator! There is a sheetmetal intake for the Supra that is shaped like a acute triangle with the TB coming in at a 45 at the top of the "funnel" off to he side so every port has a line of sight to the TB. That would kick the TB out to the side toward the driver headlamp bucket. Equal length runners triangulating to 2 locations straddling a TB would be another design. This keeps the TB centered on the port inlets. Cast it and the customers will come.....

creative uses for a cast valve cover, eh? Just need a 2.5 90 to go into the plenum. BOV will possible go where the breather hole is...EFI rail to follow across a welded runner link bar. 12" total width from head so 3" clearance from M/C...T/B will be a little higher to clear fuel rail.

have you got the motor running with this intake yet? how well did it end up working?

Im waiting on China to send my microcontroller, I just got the board so I still have to assemble it. Using a prototype free-ems Jaguar 0.6 board.

Those things actually exist outside of the pages of a web site.

Yes, yes they do. I have the bare board #05. Out of a beta run of 15 or so.
