T3 vs T4 1.06 twinscroll housings, any power/response difference?
For every car that has done well with a TS setup, you can present another doing just as well without a TS setup.
I've said it once and I'll say it again, get a TS turbine housing that is light weight with a single wastegate outlet that works with an external gate and maybe even has some kind of bolt-less connection on the inlet and I'm sold...

The path is divided all the way to the wastegate valve in that hypothetical housing. It would reap all the benefits of TS and none of the down falls as it would be nearly as light as a SS setup and as simple with only 1 gate.
But it's all hypothetical until somebody makes something similar.

It will only work with some type of twin gated WG. If you use a 44 tial or a 46PTE WG it will manifold the two chambers together and defeat the purpose. Unless some how you can make the seat of the WG single valve integrated on the housing so the valve will close both chambers when closed.
The Tial has a replaceable seat. You make a "double D" seat to go with the housing and pin the connections to insure alignment.
Doesn't matter any way as it is vaporware and I don't know of anybody currently working on anything even similar in the aftermarket. Some OEM stuff using similar idea is out there though, I was pretty surprised when somebody posted pictures of something similar that comes stock on a couple diesels.

Please do... what im comparing is spool, and that wont change anything. You can also dig up the 30R graph you have on there as well and compare my spool to that as well. I think you will find the same result. And if that pull was at 25 psi, then my pull which is an 1/8th inch higher with the boost curve being at 28 makes the graph a little fishy. I'm pretty sure my boost level was at 28 psi... which would make that pull for the 35 w/ .82 at least at 26 or higher.

Surely You would expect large volume manufacturers to take some compromises. Especially when they take liability of all the parts included.
It will work, but after the 'effort' of making the manifold divided, cross-pollinating the signals (pulses) by recombining exhaust in the wastegate - moreso when the wastegate is closed - is counterproductive to the primary design concept: divided exhaust. How counterproductive this is to the effects of divided exhaust is the result of many variables (& their resulting compromises).

MItsubishi is not going to test twinscroll setups for an evo from third party manufacturers to enlighten evom posters. SOooo. the next best thing is having indiviudals use single scroll on the same exact car, then swap to twin scroll same car and see the differences. A dyno pull or something perhaps. But why do it when it works better already. Dyno time is not cheap and that time can be used to tune someones car. A better discussion is can you warrant the cost of the manifolds? Ets twinscroll manifold is far more expensive than the non twin.
Thanks!
