The system shown, works at over one "G" of deceleration (45 degrees) plus
the nose of the car pitching down a degree or two. The airplane problem is
then that this attitude will be maintained for a number of seconds. Even that
would be a long time. One "G" would produce a 45 degree oil level line. More
likely an evasion maneuver of some kind, in an aircraft, as anything close to
45 degrees would be very uncomfortable, even in a departure situation.
If this attitude were to be held for some length of time there
would be the problem of oil from the front main bearing not returning to the
sump, with a gate of some kind. You could dummy up an engine an clamp on flat
plates and a gasket to determine how much oil would be retained ahead of the
hole. I suspect that even this is no problem.
Other options for oil pan shapes are available. The pan need not be
symmetrical. The major volume might be displaced to one side or the other, if
space is needed for a radiator or other pieces. It could be displaced to the
front or the rear of the engine.
The pick up at the engine can be a steel dash 12 male brazed to the tube.
(I love braze) a flex dash 12 line is used to connect to another dash 12 Male
mated to the pickup fixed with screws in the bottom of the pan.
We did this in the Lotus Super 7 to keep the junk engines together. (ford
3 main bearing 1300CC industrial engines). Then expanded to 1500CC with a good
7 main crank Then to 1600CC as in the 71 Pinto. Damn fine engine. Base for
Cosworth engines but they were cast in high nickel of course. We had one in
Magnesium. Real good engine. Still available if anyone needs it.
You can also use the upper end as above and run the dash 12
hose through the side of the pan to a brazed in place bulkhead fitting.
The outside end of that fitting would be a dash 16. The pan need only be deep
enough to account for the hose. The outlet for the oil from the pan then would
be a 3" hose to a pot located anywhere below the engine. The dash 16 hose
would run alongside to the bottom of the pot to take oil back to the pump. So
long as the oil level on the dip stick shows close to the stock oil level the
pump works as stock. No problem.
Two more whole generations of oiling are available if you want a
single stage external pump, or, a whole dry-sump system. In that case
the pan is just a flat plate. I can draw them all, If anyone needs
them.

Lynn,
Just what I needed !! Thanks........What would be
your thoughts
about a hinged flap on the firewall end of the plate allow drain
back
during normal or low pitch climb out but would close during high
pitch climb to keep oil out of the front cover (Tractor
installation)?
