It appears that the system has a restrictor on one side and the hoses were the wrong way around. Switching them around seems to have fixed it. Or it was the compressed air.
P, perhaps a budding car-girl? As we know, a rarity for the car-guys of the world...
Yes, my oldest... she’s loves speed, whether that’s swimming, skiing on snow, water skiing, or flying a propeller plane.
I took my middle daughter to her volleyball game over the weekend with the car in the 5000-8000 rpm range. Her comment was from a slightly different perspective: “‘How is _any of this_ even remotely legal?’”
Neither is afraid of getting her hands dirty with mechanical things.
John Kuhn had a crankshaft manufacturer create a model of the 928 S4 crankshaft and then a CNC program based on that model to drill out the existing plugs, drill the crankshaft such that all mains and rod journals are connected into a single oil passage web, and thread the old and new holes for taper thread plugs.
Again, not cheap, but he can now replicate the process at high but not absurdly high unit cost. Less than a new crankshaft!
This setup allows one to both personally clean the crankshaft completely before the plugs are installed while making it more robust to the main girdle separating excess air from oil into #2 main.
John had a CNC program and fixture to groove and drill the center main #3 bearing, too.
Peak boost 1 bar and peak rpm 8100. And of course, loud in the drive on lane...
So far, the car runs incredibly well at 8000 rpm. I’m regularly bouncing off the rev limiter, whether because of the tire slip or just for the hell of it.
Photos of the hole thru which the o2 sensor wire goes thru
Does anyone have good photos of the hole thru which the stock o2 sensor wire goes thru? The reason for me asking is that I want to know if LSU 4.9 will fit they the same hole.
All o2 sensor bungs are the same thread , whether narrow or wide band from memory 18 x 1 mm thread
I was thinking about the hole in the floor thru which the sensor wire runs and that one has to push either the sensor or the connector thru. The narrowband sensor connector is much smaller than the wideband sensor connector so I was wondering whether the hole is large enough. Also, is there a grommet and if so does it have a slot cut thru it?
It wont fit through with the connector. You need to pass a de-pinned harness through and then add it under the car. You can retain the factory grommet that way.

Thank you! Let's hope the LSU 4.9 connector de-pins easily.
Thank you! The LSU 4.9 loom would need at minimum 25.15mm hole without any connector disassembly, and that would be by snaking the sensor end in from the inside.
Here's another question. I searched the WSM quickly but couldn't find the answer (probably a user error). What logic is used to operate the air conditioner clutch? Does it just go on and off based on the AC button on the dash, or is it similar to modern cars where a computer operates the clutch based on the engine state?
