No to re-hash this, but on the issue of dry sump engines, why not just use the ole American hot-rodding part a la Chevy Z28's of SCCA Trans-Am fame: Windage trays. Sort of acts to baffle the oil pan and keep the yummy black stuff where it belongs.

The problem with the 944 oiling system is aeration of the oil. Basically the oil gets whipped up in to a froth by the crank. Oil foam is not a good lubricant.
The oil level in the pan of a 944 is within ½” of the crank, now add in a little lateral force or braking force and the oil hits the crank. Oddly enough the popular Accusump fix will only make this worse as it dumps a couple of extra quarts in to the sump at hot idle.
Dry sumping is the only ‘real’ fix and a done correctly figure a starting costs of $3 to 4k. Of course you could get fancy and spend a bunch more….
