alright so it looks like wayne_curr is going to be building me manifold soon but I found out the other day I need some damn pisons now and I can't find anyone that has them in stock and I'm not wanting to spend the money on forged ones cause then I'm gonna want to get rods then springs etc

Because that's what everyone else uses?
Every now and then I consider making it, as well as a ramhorn manifold (which is easier to build)
I don't think it'd last long enough for my lifetime guarantee from cracks
Tim, you'll never be out of work. You have a cult following. You're an innovator in the miata community. After all, who else has a TT miata
BTW, I'm not trying to start a pissing match. Each design has it's advantages. I too have thought about making a dyno comparison of the different designs, but 1) I'm not footing the entire bill, 2) The doubters will say it never happened, or somehow the numbers were skewed (just read the 10 pages of bickering on the link above for an example).

Top level N/A headers, that's another story.
Can't really say that if you've never built one. Build it, then decide. To me an Absurdflow looks easier to make, but I'd imagine there are things I'm not taking into consideration.

No one want's the TT's. Boooo. i'd really like to sell them so I'd have money for a suspension for the subaru hahaha

Maybe I'll make Sav a ramhorn if he wants to try it.

I think there are very few race teams who actually do R&D on their turbo manifold design
It is difficult to make long 3-d cuts in multiple pipes that all have to merge at one point
No one want's the TT's
I want someone with a turbo large enough that may benefit from a ramhorn

Nice spot for the power sterering But that's your car you use to mock up, right? Nice manifold. Looks simple
I don't have a shop. I display the TT's on the floor of my utility room. It's in the box next to the dog food. Don't trip over it.
Absurdflow mani's are very simple to weld. It's the cutting/fitting that takes time. I've found templates to be rather disappointing due to great variances in weld elbow cast size/shape. Not all are the same diameter or 1.900 OD, not all are 90 degree, etc. Mild is worse than stainless in that regard. I've tried to make templates from what I've done before but it's only a guestimate when it transfers over. I'm sure I'm missing something but whatever.
I don't change tips or diameter electrodes or whatever at all. I only have two electrodes, big for the mani's, small for the downpipes, whatever came with the welder has worked fine for the past few years. Still not using a glass lens. I'm a basic self taught welder. Lotza stuff is probably done wrong. I think using the steel electrode is much easier on aluminum than the 100% tungsten, so I use that instead.

Lol yeah, I'm building off my car, and would like to keep everything together in case I ever get to drive it again (it's been sitting for almost 6mo now).
What about Shore MS? Will they let you put it up for display there?
I guess I haven't done enough carbon steel to notice the difference. I figured making the ballpark cut, then taking it to a belt to fine tune would be easy, but if the elbows vary that could be a problem. Do you buy from a single supplier? I requested that all my elbows come from the same mfg, or at least the same country. I wonder if that would solve the issue.
As for the electrode, you have some variation of tungsten. Ceriated, thoriated, lanthanated or pure. Steel would melt right off. I use 2% lanthanated for everything, but with these newer inverted machines it really doesn't matter as much as it would on a transformer welder.

How do you guys think this will perform against the FM/Begi cast mani's that a lot of us run?
