Just a thought, and I don?t know why. But with the renisis side
 porting, or peripheral porting. It wouldn?t be very hard at all
 to make a  rotary engine run the opposite direction if a person
 needed it to. I wonder why I care?

 You are probably thinking of a twin.

 It will run backwards but the internal cooling would be all screwed
 up :)

 It would work perfectly in a parallel universe.

Paul,
With a few of us working on billet machined side housings (with steel
inserts), the  cooling pattern and bolt patterns could be mirrored and
the
rotor housings mounted rotated 180. This would give a reverse rotation
rotary that had identical performance, both hp and cooling. Other
stuff like
the oil and water pumps would have to be reworked for rotation, but very
doable.
This would provide a great twin set up.

We might even sell one :)

Then we will have to deal with the law of unintended consequences.

I think we are twenty or thirty years ahead of our time here.
Perhaps when I have my 100th birthday party.

First we must get 100,000 rotaries flying :)

Why wouldn't it be easier to beef up the e-shaft and use the other end
of the engine  for power output?

Much cheaper and more likely to work.
The required modifications are extensive but not nearly as bad as
running
the engine in the other direction. A new front cover would
need to be designed and built as well.

Paul:

For what it's worth, I'm designing a counter-rotating twin with this
very topic in mind.Instead of reversing the direction of the engine,
I'm doing that in the PSRU by having one gearbox with a stationary ring
gear and revolving planet carrier.  (1+R/S)  The other would use a
stationary planet carrier and the let the ring gear rotate.  (-R/S)Of
course, the gears would be different size for both the planets and the
sun (input gear) but the ring gear would remain the same size to allow
for the same exterior dimensions of the gear casing.  End result would
be a 3.0:1 reduction in both directions  (i.e. with a ring gear at a
constant 96 teeth, the sun at 48 will give 3:1, change direction by
replacing the sun gear with 32 teeth and, of course, a different and
fixed planetary carrier will give -3:1).  Yes, all the gears will be
custom but that has to be a heck of a lot cheaper than reversing the
direction of the engine itself??

Greg in Canada  or on Canada if it is not snowing.  It would be nice to
see a jpeg screen capture or drawing posted of your PSRU. You haven't
mentioned if you are planning on constant speed, and the design HP and
weight. If you have started cutting parts do you have pictures?
