The AC is separate but does send a signal to the computer to raise the idle.
The LSU4.9 plug will not fit through the floor and the sensor itself cannot be depinned. You have to run the connector under the car and just run the wiring through the hole. I have yet to have any have corrosion issues this way.
I use the Innovate Digital MTX-L as the wiring that connects the WB controller/gauge fits through the floor without any issues or modifications required.

My preference is to expose as little of the sensor wires/loom and connectors to the under car elements, including exhaust heat. Because of this, I’m leaning towards making the hole bigger (1”) and having all those inside the car. With 1” hole, I believe the exhaust sensor can be pushed out from inside the car, even if one wire is already going thru the hole.

In any case I would leave the connector outside, for the ease of replacement. Never had an issue with mine located over the torque tube just behind the bellhousing, and it's getting a lot of heat there (944T).

You can always drive with the side window open, but it increases air resistance and reduces top speed.

What would the top speed even be with G28.13 on fifth gear and the peak power rpm at about 7250rpm and redline at 8000rpm? I’m thinking that opening the window or sunroof at that speed might cause problems bigger than a reduction in top speed.

American street cars by the definition of an American street car have working air conditioning.

Keep in mind that an engaged A/C compressor reduces the power at the rear wheels, which also reduces the top speed of the car probably by about one mph.

A Euro G28.12 would be 28 mph per 1000, or 224 mph at 8K.

Hey, you can do 0-60 pulls in 1st gear.

A rough calculation tells me that the 928 engine power needs be appr. 750 HP for a top speed of 225 mph and that is if Tuomo is driving with the windows closed.

On the "drill baby drill" project, there's now round 1" diameter hole there slightly offset from the original location. I had a wooden staff on the other side pressing against the hole such that I could locate pilot slightly offset away from the turbo speed sensor hole. I deburred the hole first, then smoothed the edge with a stone on a drill briefly. You can run a finger over the edge without getting feeling it rough. The oxygen sensor now fits thru, barely but it fits. I added some rust proofing there as well on the bare metal, what looks like burrs in the photos is in fact just the rust proofing substance. That was my lunch hour right there, back to the regularly scheduled programming...

According to the standard wiring diagram the clutch solenoid is disengaged at wot , obviously the factory didnt expect you to have the pedal floored constantly
