I didn't know that...
I didn't know that Christopher Walken was a "yes, but..." guy. ;-)
The system is pretty symmetric and the symmetry can be verified from the speed sensors. The bung locations are pretty symmetric, too, which makes these pick-up locations convenient. There's a bung in about the same spot upstream and downstream of the intercooler on both sides.
These sensors in the schematic are for dyno only, st2 and EB2 have their own sensors. The dyno sensors are in locations in which sensors might in regular road use have "issues". The permanently mounted sensors are in locations that should be reasonably safe for the sensors.

Remote turbo oiling
This might be useful for people who frequently swap turbos or other remote components that require controlled oil pressure. No need or room for it in my car, because the restrictor calibration works fine and did I say there's no room.
An obligatory photo of me working hard remotely included. Telecommuting to work rulz!
God, does this iPhone interface suck hairy *******...

Coolant lines
This is how John designed the turbo coolant and other hardlines. He first mocked them up from soft copper line and the hardlines were then fabricated based on these models.

626? That can't be right - that's a Mazda!
And yes, I do know the Lilo & Stitch reference, so don't bother explaining.

Space
A quick word on that AOS hardline. Since the lines potentially flows oil downwards and gas both upwards and downwards, it has to have a relatively large diameter, much like the block oil drains. The large diameter and the requirement for a relatively straight path down make running the drain line a space challenge. The solution is to run a rigid hardline from the turbo oil sump to above the exhaust manifold level and then a rubber hose above the exhaust manifold level. This way, the hardline will move with the engine on the motor mounts where the space is tight and the the rubber line section will give the compliance for the AOS to be loosely anchored to the chassis.

Inlets open wide
Greetings from South Africa! Here's a visual of how the filter will integrate into those large inlet pipes. There will be two openings cut to the filter element and outlets attached to them.

As big as can fit:
The compressor inlets are now true 3.5" OD stainless pipe all the way to the silicone inlet boots. A challenge to fit them, but John was able to put together the puzzle:

Fuel system testing.
While I'm having a rough month traveling, John's testing the fuel system. Everything seems to pressurize correctly, no smell, no leaks, and pressure holds well downstream of the check valve.
Personally, in November I've done two World Series games in Chicago, long weekend in Disney World, some private clubs in London, a week in Cape Town, and now Thanksgiving in St. John. This was supposed to be my vacation month, and I feel like I need a vacation when I get back from vacation! How do the Europeans do this every year with their seven week holidays???
