it'll flow slightly slower than the log (we're talking about +/- 100 rpms probably)...but the extra "directional exhaust guidance" will help it flow much better after that. That's a really short merge... a smoother and merge where the exhaust from the primaries have the least amount of "i'm going to run into you before I leave" will net the best flow/power.
Here's a log vs. ramhorn
FINALLY -- TURBO MANIFOLD TEST (What happens when a log manifold is changed to a Full Race Manifold? - Honda-Tech
There's really not much to it. Allow the gases to flow and merge with minimal interference. This nets highest flow... flow = power, no?

When talking about a standard log manifold you're damn skippy that its not going to flow as well. Just look at it.
I'm more intrigued by how this might flow and spool versus a ramhorn style.
And I should be finding out fairly soon as i'm going to be hopefully building 3 or 4 of them as soon as some people get their **** together and buy parts. I'm not even charging for labor, just building them at cost for fun. Actually bob bundy built a manifold with the same concept for a 323 GTX so he should really chime in here. I dont want to post a picture of it without his permission.

When using a garrett 56trim T2 flanged GT2871, that above manifold places the shaft at the same spot as my standard manifold.
Every now and then I consider making it, as well as a ramhorn manifold (which is easier to build), that places the turbo in the same spot (so downpipes are as equal as possible) and running a comparison. But then I realize it really doesn't matter as everyone will have their preferred option. You can get a ramhorn from many places so i don't build them, and I don't think it'd last long enough for my lifetime guarantee from cracks. If someone comes out with my manifold for less than what I charge and demand drops, then I won't them either
I also agree that actual construction plays a huge roll in how well the manifold performs, in terms of how smooth everything blends together.

I should start putting watermarks across my pics I guess.

Tim, did you make this mani?
Id be interested in something like that with a dp for my 1.6.

Sorry Tim, didn't mean to offend or take credit for anything, was just using it as an example. And as far as it not mattering whether or not you build it, I think you've got enough clout that if you build something and give it your blessing, it will become a lot of people's preferred option just like your current design...

But I have a 1.8 so no downpipe can be made or guarantee of fitment. I'd have to build it on a bench and hope it doesn't hit anything.

Mild steel would be fine, could get it coated before installing.
Just flipping it around might work. Either way, that's a simple fix.
