I had the same question on my midpipe's v band flange. Turns out it's a flange used in food processing that Abe @ ARTech uses, email him and he can get you the aluminum gasket that goes in the slot.

So back to my original question. Do they not leak at the cut in the o ring, and drive the o2 sensor crazy?

If I were to guess the o-ring expands when hot and seals.

Just a guess.

If it's designed to leak a bit (which I would hope not) then I would change it so that it does not leak before the O2 sensor for your reason mentioned. Yes a leak will drive the O2 sensor nuts. So gasket with no break in it, or a different V-band connection like most that you surface flat after welding and then bolt together gasketless.

Since my computer is on hiatus, I decided to move to other tedious things. Like a turbo heat shield. Does this look super lame? It's a tough spot, not much room.

Looks badass. Just like my license plates. The curve is pretty good. I think a roof for it is supposed to help too.

Can I change my title to " All this for a 2560" ?

Hahah, I saw your plate, that's where this was born from. I think I will add a roof.

I haven't forgotten about you...I have been adding in some detail to the coil mount, so when you have it cut, you won't have to screw with much.

Looks good. As mentioned build a roof for it. Maybe one for the turbo manifold too.

Aww shit. Sounds like this might need to be a big piece.

Could be separate pieces. I did a heat shield for my header a while back and it made an amazing difference in heat management under the hood. If that's your goal, I have to recommend it, it works.

Pretty sure I posted this already, but damn I like the attention to detail on that engine bay. All the little things for reliability... Hardlines, oitkier clamps, clamps to restrain things from moving, etc.

I have an Artech side mount that uses those gaskets. They look like aluminum filler rod for tig welding. You could get some rod and cut them slightly longer?

Haha! Someone else knows Oitiker! Thanks man, it's a sloooooow work in progress. Lots of exposed wire from electronic gremlins. I'll fix it soon enough.

This was my next try for tomorrow. Good thinking.

Pat, what is that ultra shiny stuff?

I used those clamps to make A/C lines on my car, and they worked for that. Those things are awesome for anything permanent. I know the slooooow part, same for mine. It's slowly starting to become what I want it to be.

Mirror polished stainless steel sheet metal I bought on Amazon. Emissivity of ~0.05. Very good at blocking radiant heat.

I sense a little bit of hate around here. I don't think some people understand that I have sold literally everything that I owned to build this car. As well as following 18's advice and making my full 401/ Roth contributions.
