I already thought about the oil issue, but figure that the stock-in-car
engine won't have a problem.  We'll drain it before pulling the thing
out of the car so it will have fresh oil for the demo.

However, even if the thing only runs an hour without water (which has
been done in at least one car that I know of), that's about 59 minutes
longer than any other water-cooled engine will do.

Essentially, I'm not promoting the idea of an engine which doesn't need
water so much as an engine which won't seize and kill you if you lose
the water inflight.  While I expect that it will stay running, this IS a
test-to-failure demo.  That's one reason for the big clock -- if the
engine fails, we stop the clock then challenge any other engine to match
the runtime.

Of course, we'll run a fan through the oil cooler and over the engine,
to simulate inflight airflow, and that should help a little.

Keith,

Just playing devils advocate here....

How is running a water cooled rotary without coolant until failure
going to show the masses that it is superior to an air cooled reciprosaur?
The air cooled recprosaur does not have coolant to loose....

One thing both engines have in common is a pressurized oil system,
however, if either engine looses oil pressure, they will both seize.

I guess I am just not sure what the demo will accomplish.
