So far mec and firefox are the only ones that have asked, if the first one comes out good I’m willing to make more. I just want to make mine first because its going to take the longest and I want to figure out all the little kinks before someone pays money for one.
I might want one too. What kind of stainless do you plan on making it out of and what wall thickness?
We recently made a tubular manifold. Cost of supplies and labor for all of the trial and error far exceed what it could be sold for. But that is what it takes to make a good product the first time.
Hello, would you guys be interested in something like this, GT28 up to GT40? Stock motor beta car felt absolutely amazing a few years back…

The Vast beta car?
Another reason why i want to do mine first,but im confident ill get it first try.
those welds seem a little hot. Are you doing two passes or trying to make it with one?
No not at all when there’s to much heat involved there is no color & the material will turn really dark brown almost burnt looking which makes the welds kind of chalky. If any cooler the rod wouldn’t melt 
this is the color you want… Pulse weld near 1/4" thick material.
I’m not talking about color, a few of the welds are concave. If your welding cold like you said then your not using enough rod and i doubt your getting proper penetration.
No No full penetration & fully purged. I’m saying not hot to where the material is actually breaking down & if too cold you couldn’t weld this material or fully penetrate.
I would wait to see what Derrek comes out with, there isn’t even a twin scroll manifold on the market for the FSI, so Derrek’s is going to be the fastest spoolin! Perfect for a twin scroll t3 or 7163
IMO you should have a fuller weld that’s not concave, also it looks like you didnt weld the inside of the runners where they meet the flange.
Twinscroll 7136 is T4
People have tested twin scrolls in many different platforms including the A4 1.8T & have seen no measurable spooling or performance gains anywhere & definitely not on smaller framed turbos. There are far to many variables involved to just say a twin scroll will spool or out perform a single scroll. “Just not always the case”
are you trying to say a twinscroll and singlescroll turbo spool the same? proof please
Yes you are correct, there is no reason to go out of your way to do twin scroll… thats why BMW has started to do it, they just enjoy throwing money down the drain

so is mitsubishi in the EVO, subaru, mercedes and now vw with the ea888.3 engine
But I’m sure you are correct, there is no reason to put twice the work in to make a twin scroll manifold when it’s just throwing money down the drain.
16 years of successfully building them so definitely not our first manifold nor was this the first of it’s kind as we built that setup in the picture in 2009. You don’t need to weld the inside of the flange section if things from the outside are done proper & many people/builders don’t for other reasons but rather not get into all that. Thank you for your comments though
I see were this might be going & why. Hope everything works out with your project.
Not trying to argue with you at all but definitely not comparing apples to apples in terms of high performance manifolds & turbos vs factory manifolds & turbo etc.
