Not bad, not bad at all
You will need that heat wrap though especially for the folks who decide to keep their IMRC plates operational as the cables will pass exactly through that area.
I think Lonnie's solution from years back had similar shape to it.
You're right, and I'll probably recover the upper part of the stock tube with something like that. Unfortunately, I needed to remove the stock covering so that I could understand how to solve the problem.
Got any extra left?
So, I believe that I've figured out a slick solution to the EGR tube issue.
Turns out that the upper end of the Gen 2 tube has some flexibility built into it.
So, after a little judicious bending, I was able to position it where I could create a short extension tube using the top and bottom ends of a '98 Cobra EGR tube. The extension tube I made will mate to the Gen 2 tube behind the intake. I'll have to put a copper or aluminum sealing washer between the tube ends, or perhaps I'll make a small double cone from aluminum on the lathe.
I need to finish welding my extension tube and find something nice to wrap it in, perhaps this DEI wrap from Summit. Or, maybe I'll send it to Jet-Hot and have it coated.
I'm not exactly sure why I went to all this trouble, but I did want to see if I could do it. :wink:
So here are the pics.
I sent DEI an email and asked if their Cool-Tube Extreme would work in this application.
Bear in mind that top section of the the stock Mark VIII tube comes wrapped in a fiberglass sleeve similar to this, which is what I bought:

It's good for 1000 degrees. The wrap you're talking about would serve the same purpose, but I would think that a loose fit would actually do a better job at protecting stuff around it because you've got a layer of air between the tube and the sleeve. I bought the 1 inch size.
Doug, have you looked yet at the vacuum lines for the EGR and FPR, etc.? Just wondering how many mods will need to be made. I looked around and can't find anything to match those lines in the event that any splicing would need to be done.
Unfortunately for me, here they still do a visual to make sure you have not deleted something:
So if there is no solution to the EGR fitment problem my Cobra intake will be for sale and I will be looking for a supercharger instead. If DLF can't make it work, it isn't going to work.
Looks like you might look into doing the c-head swap instead.
Lonnie has done a cobra swap and install a egr. he did it on his 96 and don't know if he has done a gen 2. Here is his email. Not sure if it still active. lonnie@blueovalchips.com
... but I decided to make one on the lathe from Delrin.
Your fabbing skills are priceless Doug. This is starting to look really good and you are definitely thinking this one through thoroughly. I am excited to see as you progress. I am slightly jealous how clean this is turning out.
