Yes, hose from master to the t/o bearing. No Fork, no Slave.

Pre S4 928s also featured a twin disc clutch from factory, if I'm not mistaken.
Mike, how is the release bearing attached to the bellhousing?
I suppose it uses the 3 bolt holes for the stock bearing guide? Will this allow enough clamping force?

Eight inch diameter light weight multi disc clutches in motorcycles hold 150 lb ft and work wonderfully with butter smooth engagement. Why shouldn't this one be just as good?

Yes, it attaches in the same location. This is a Push type pressure plate, rather then a Pull type like the stock. So it is pushing against the bell housing, not pulling on the bolts. The clamping force doesn't have anything to do with the t/o bearing.

SOunds like the Mary Poppins of setups to me. "Practically perfect in every way possible."

If the goal is to get maximum boost in 1st gear, then absolutely a lightweight flywheel is counter productive. I'm actually not interested in getting max boost... I want to accelerate the car as fast as possible. A heavy flywheel gives you more time in lower gears, which is exactly what I want to reduce. You can do the math on how much power it takes to accelerate the clutch/flywheel assembly and it's not insignificant. There are drawbacks, but accelerating the vehicle is not one of them.

How much weight can you shave off rotating assembly on street 951 so that it sharpens its character, but still retains road driveability and stockish idle rpm?
Would knife edged (not to extreme) crank, aluminum pulleys and aluminum fw be overkill?

I have done all of that and my car runs great and I have no complaints. Glad I have done it and am very happy with my project.

Why did Porsche keep the heavy crank in the 968 when they used lighter rods ?

With a 150 lb ft and 160ish bhp they work just fine.
