Supercharging a 944 - Why so hard?

Yes, I do have a Volvo C40 PS pump. Trying to figure how to mount that. That was my first idea on how to keep AC.

Yes I will need a custom M62 pulley around 80mm for the modest boost level I am going for. There is a gentleman in Hungary who makes those.

The only question is how much fluid do I need in the reservoir? Do I only need enough that fluid stays above the intake at all times?

My brother is looking to sell my entire Supercharger setup if anybody is interested. It is not a kit but comes with everything you need to supercharge a 944(with some minor/major mods)
Comes with DME(Rogue) with tuner and logger.
Rogue NA-Tune with custom stainless MAF tube
Eaton M90
Top view of where the SC was fit.
SC Mounting bracket
Intercooler and piping
and much much more.
Its a great way to get started, most of the hard work is done. around the $1700 range for everything.

Look what I pulled! I may have started a hoarding problem.
Thinking about using one of these IHI twin screws vs. an M90.
Advantages:
Higher boost potential (I need that at 7000 feet)
More efficiency (~64% adiabatic efficiency at 1.8-1.9, vs 62% at 1.4 for the M90)
Less heat
Cool factor
Thinner form factor may fit better
Sound?
Disadvantages
Harder to find refurb parts
Less volume per Rev (~73ci)
Has to be plummed to oil supply
Given the potential to drive it harder, I'm no too concerned about the volume defficiency. Tapping the engine for oil shouldn't be too hard, but mating it up to the supercharger may require some creativity. Do you think I could turn it into a sealed unit?

Lachlan - still digging for those parts I owe you.
Those Mazda units are super cool, I thought about those once (I also owned a Millenia 10 years ago) but the lack of parts was my concern.
Millenia S owners have to buy new ones at $3k apiece if their original one pops, but you might be able to scavenge parts from multiple units to make a solid one.
73ci per rev is still plenty for a 944 motor that takes 75ci/rev at 100% VE...just add overdrive to the blower.
The skinnier case will be a huge help in packaging.
