Jerry,

   Maybe it's just a holdover from my drag racing & SCCA
days, but I get really nervous looking at an oil pan with
a shallow slope.  If that diagram represents a tractor
configuration, during steep descents, you could very easily
find yourself with bubbles in your oil line.

   If your cowl will allow it, you might consider moving
the radiator forward a few inches and accept a gap between
the bottom of the original oil pan and part of the ductwork.

Here's a mod to your drawing that I'd feel safer with.

Or, add some baffling to retard any major flow of oil "up"
the slope.

Subject: [FlyRotary] Modifying the Renesis oil pan

After careful examination, I believe the Renesis oil pan is relatively
easy to modify to add capacity, place the pick up in a deep reservoir
of oil, and have a shape that corresponds with the wedge radiator
intake plenum. Basically what is being proposed is simply extending the
sump downward.  After removing the baffles that are bolted to the
inside of the stock tank and the low level sensor, the bottom of the
tank can be drilled as required  to form an oil air separator  and to
provide an opening for the modified 13B pick up.  Then the wedge sump
is added (welded) to the the stock pan.  The wedge sump would be .063
steel.   Obviously,  there is plenty of room to modify this picture
depending on the particular installation.  For example, if one did not
intend to put the rad underneath, the tank would not require the wedge
shape.This looks like a job most of us could do easily in our own
shops.  Jerry
