My Mid-Mount Turbo System - After One Year of Use
#32
@grepin , it's even simpler than that. I took a Banks windshield mount dual gauge pod (https://bankspower.com/products/gauge-mount-63344-idash-52mm-2-1-16-in-gauges), removed the pods from the windshield mount, and popped them onto the ball for a generic CD slot mount with the same sized ball. Then, I inserted the CD slot blade into the gap between the center console and the dash. With the wiring plugs in the split loom, I can remove the gauge pod and tuck the wires away in a few seconds.

The new wires that I added for the system are:
1) Wide band O2 sensor - I ran this wire through the same existing hole in the floor pan as the stock narrowband O2 sensor.
2) Gauges - These are wrapped in split loom with quick connects inside of the loom for easy gauge removal. The wires (in the loom) run along the right/passenger side of the center console and between the carpeted block off panel for the center console and the parcel shelf into the CE panel area.
3) Manifold pressure/vacuum sensor - This wire runs through the O2 sensor wiring hole in the floor pan.

Some of us saw the car this weekend in person. Bulvot put it onto the lift and gave the grand tour underneath. It should be evident from all the other posts, this is an engineered system, optimized for practical GT car use, addressing secondary issues too, such as crankcase venting. Pretty amazing.

It is a transformative upgrade and I highly recommend it

Free energy recovery just makes so much sense to me and the 928 is such a deserving platform to start with and the increment as you say is going to be so very transformative. My Cayenne turbo S with 520 BHP gives me some insight into what you must feel even though it has about 700kg more baggage than the 928. Just wish the 928 had that go and the 6 speed tiptronic box to go with it!
We can but wish!

For anyone who comes after me and goes the turbo route. Tial no longer posts the bench testing procedures for their wastegates. I've attached it to this post for posterity.
For tools, I used an OTC 5609 Cylinder Leakage Tester to regulate pressure from my shop compressor, and two Measureman pressure gauges plumbed in parallel (0-30 with +/- 0.3psi accuracy, and 0-15 with +/- 0.15psi accuracy).
Here's a photo of one of the gauges and the wastegate:

This is from yesterday's drive to church. I had two passengers with me, a full tank of gas, and my usual spare tire and tools. Hence the high weight. Unfortunately, I also have my winter tires on, so it took a bit to get them to hook up, which is why it starts at just under 3,500 RPM. Prior to that, the wheel spin really throws things off, so I cut that portion out.
