It's to get better departure angle. We've never had a ground clearance
problem, the current design suffers from decreased departure angle
because of the rear cradle bar(granted you can drag scrape and try to
wreck it and it'll hold up, and not need paint afterwards still) but
anyhow the ground clearance is limited by the adapter plate and bell
housing once we go to the dry sump, but with the dry sump we will have
better departure angle than the stock wbx, along with the 8-12 quart
res capacity. It'll also allow us to have full undercladding in the
rear. The only thing I don't like about the dry sump is as David
points out, it is more complex, but we're not going whole hog and
using a multi-stage dry sump setup like race cars, we're just doing a
scavenge and feed system for the stock crank driven pump to keep it as
simple as possible, but make the increased risks to a minimum while
making the increased benefits wholly outweigh the increase in risk.
