After sending those pictures of our 6 exhaust port RX8 turbo engine, I
thought some of you might like to see some of the other interesting things
we have done recently.


Then -- more 2 rotor aluminum engine pics.
Drysumped
Titanium 1/2" O.D. studs with 10x1.0 threads - no need to rethread the front
housing.
We bored (on our studding fixture) the holes in the rear side housing only
about half way through (actually calculated the depth) so we could still use
the OEM tension bolt seals. (Had to do that because the titanium studs only
come with 10mm threads on both ends).

Inconel hand made gaskets. Showing the very special one made for my
6-EXHAUST port "RX8" engine (and a spare).


Next batch:
Anyone using the RX8 OEM intake manifold, but NOT using the stepper motor
actuated rotating sleeves will like our "inserts".
You just tap them into place (I put a little expoxy in also) to fill in the
weird shaped cavity left when the shaft / gears / valves are removed.
Supplied with a center hole -- port to match whatever you are doing.

Next:
Steel (1/2") studded RX8 turbo engine.
Can't do all the holes as there are now some new exhaust ports in the way,
and different intakes ports from earlier engines.
We had fixtures made to tightly control the holes. Drill bushings, carbide
drills, custom made end mills, etc.
Close-up shows that --- and also the "water jacket mod" around the spark
plug holes.

Btw -- We prefer studding as many holes as possible for maximum rigidity ---
but if the customer wants, we can just do the 5-8 holes around the
compression and combustion areas.

Last picture --- Progress (at ~11/1/11) on the cast titanium / aluminum side
/ multi-piece rotors.
Weight is looking right at 5.5 pounds.
Cost ???? Still trying to shoot for ~$1500 each.
Have another few months before the first TWO are ready for testing (we all
still have to earn a living).
NONE will be offered until we have done MANY many hours of dyno testing.

Nobody here needs to tell us all the reasons why you think they won't work.
There is a BUNCH of engineering already in them covering many foreseen
problems. We think they will work. It is our money and our time -- but
really cool idea, isn't it?

Exciting stuff.  Great to see some hardcore R&D going into the rotary.
