Running a three(?) quart Accusump accumulator on the Spyder and I think it's sweet. Fun to pull the switch before startup and watch the oil pressure light go out. With the "thinline" deep sump I can also run with about 5 quarts total, showing a quart down on the dipstick and still have a quart or two in the accumulator, so oil splosh in the crank case should be no issue.
Tucks in nice too. Subtle:
Easy to set up, no new pulleys needed; just T it into the return line from the remote filter or the remote oil cooler if equipped. If they work right (and I have heard of cases where they don't), a 2 or 3-quart accumulator should be all anyone with a strong VW engine needs to keep the bearings wet. You could even omit the deep sump and drive happy anywhere except maybe a banked oval race track.
The dry sump is of course the ne plus ultra. You get the oil capacity, guaranteed no uncovered pickup tube ever, and a couple HP extra (maybe) at 7000 RPM from the zero windage.
Having both dry sump and accumulator is the sort of thing only a mountain gorilla would consider. My god.
