Here are a few more...
I was going to post the pic of the injector hole fixture, but don't want to put up any free design ideas.
You can see how much better the new flange is than the original mockup. Overall design is way improved making it much lighter, and the machine work is a hundred times better. The runner openings on it are perfectly gasket matched. You can also see the dishes for the injector tips clearly in the last pic, and on the inside edge of the runner opening in the first two. They look exactly like the dishes on the stock flange do, and are very well done. Lastly, notice the machined lip for the runners to "lock" into. This will be implemented on not only the flange, but also on the plenum floor, so strength and longevity will be top notch.
The blue line on the mockup plenum is the new roof-line. That revision will get us right back into the ideal range as far as volume goes.
So, everything looked great and I signed off on the final design. Wes and Kelly said they would try to get it done for me for next week, so we'll see very soon how this b**** does in the real world. As soon as Kelly has his machine time logged, I'll know how much I owe his boss for the machine time, and I'll be able to figure out the end cost for you guys.
edit- almost forgot... EGR guys, I made a revision for you as well. The setup will now be a little cleaner and there won't be any weight dangling off of your stock EGR tube. Basically, there will be a flange on the underside of the plenum that you will bolt your stock EGR valve onto. This obviously won't be in the same spot as stock, so I will provide a flexible line that will run from the end of your stock tube to the new inlet on the flange. I am hoping that this will also cut the cost of the EGR option a little.
Will update again as soon as I get news from Kelly and Wes.
