Turbo Manifolds
I generally don't crosspost, and I know it's frowned upon, but hopefully this exception will not result in a headwound 
As many of you have been following along, you know I'm building a 500cid twin-turbo stroker crewcab (albiet very slowly), but every once in a while I have a massive spurt of energy that coincides with some free time. Then, I end up making something useful for a change
This is the passenger side manifold. There still is more work to be done on it as there is some welding slag I missed and I have to port-march the header flange to match the heads, but since the heads aren't done yet there is no sense in starting this on the header plates just yet.

looks pretty good frederic. they look pretty heavy duty as well. Just a thought, those turbos will be positioned about right to run dual chrome exhaust stacks straight up through the hood.....lol

heh-heh.
It's made of "black pipe". I debated going the typical stainless route however acquisition would have been more work and cost than driving 5 minutes to a home depot. So, black pipe it is. It's 1.75" or 2" OD tubing, with a wall thickness of about 1/8". I think it's a hair more, so maybe it's 3/16" thick. Eyeball measurement.
Coincidentally, I acquired a spare hood and modified it so the turbos will "sit through". It's amazing what one can do with a metal cutting blade in a circular saw, and some angle iron
. 
The hood pictures were taken two summers ago just after welding. Unfortunately it's a bit rusty at this point because I put it at the side of the house and forgot about it for a year, then put it into the garage and it got banged up a little bit when I was wedging an old sofa in there.
Anyway, the angle iron sticks through the hood about 3/4" at the front, and about 1/2" the rest of the way. You can't see the tapped holes in the pictures but there are quite a few. The intention was to build a slight "dome" over this large hole out of fiberglass over a cardboard buck, and bolt it to the sides of the angle iron frame that's welded in. Then the turbos won't hit the hood, as that piece is completely missing (and raised by the "dome" I haven't made yet).
