I imagine the pressure ports are probably being used to validate their design and are not part of the final design.
A large A/R divided stainless turbine housing with external gate would be AWESOME. It's probably the only thing that could ever get me back to a stock frame setup. "No" to the stock downpipe flange though, make it V-band.
Edit:
WHOOP!
I see an external gate there on the side of the turbine housing!
Sweet little position sensor on the back of that MV-S gate too.
Turbo inlet pressure sensor
That's about all I can make out on my phone.

Two banjo bolts, not sure what's going on with the orange hose, sensor coming off turbine housing (or is that the O2 sensor coming off the O2 housing?), what looks to be the BOV port coming off the intake is capped. Ok done guessing lol.

In general terms, would exhaust pressure tend to be higher at the four individual sensor locations on the manifold, or at the inlet area of the turbine housing?
EDIT: Granted, this is s loaded question.

Just talking average static pressure, I would think it would be higher due to frictional losses in the runner. However, you might get some pressure recovery as the airflow slows down with the increase in volume at the collector. On the other hand, its pulse flow so the whole manifold might be at the same average pressure and you might have to look at the individual pulses to see a difference.
Definitely a hard question to speculate about. No idea on factual measurements as the only time I've seen taps like that, they were running at a very high sample rate and relating instantaneous pressure level to crank position. That has nothing to do with average pressure though really.

hey michael, gotta love swagelok. i've been reading pressure off a single runner without significant issue for a long time now. i get some pressure serrations, but nothing that obscures what's happening. i did just recently have English put 1/8" npt taps on the remaining runners, so maybe i'll combine signals as you have. i probably should compare pressure in the two scroll paths as well.
