a) I read somewhere that the Renesis side-exhaust is
ceramic coated to avoid warping of the sidehousings(?).
Anyone yet considered to convert a 13B to side-exhaust? It
is done constantly for a peripheral intake - is there a
reasonable way to convert to side-exhaust? Maybe with a
machined aluminium-piece - ceramic coated and then welded
into the side and centerhousing?
b) What would be involved to make a complete new
centerhousing for a Renesis, that would be wide enough to
house 2 fullsize exhausts like the sidehousing? This way
the way would be open for 3-,4-,5-,6- rotor engines!! In a
centerhousing, are there any embeeded steel or alloyparts?
Or is it basically just an aluminium or alu-alloy part?
Thanks for your time!
Back lurking and dreaming!

The current center housing is cast iron. To make it wider would
require a longer e-shaft of course. Doable but I think I would also want
a center main bearing. Perhaps a two piece center housing to easily
accommodate a center main bearing. Here is an old patent on such and
engine.
To convert a 13B to side exhaust would be very, very difficult.
You might as well start with an RX8 motor. What I would like to
try is a side exhaust with a peripheral intake port.

Hi Paul,
13B side-exhaust:
The general idea would have been a easy conversion to use the 13B which is
plenty on the market AND get the benefits of the side-exhaust! I guess -
forget that!! I am afraid it will take a while until the Renesis is widly
available on the aftermarket.
Any idea how much a Renesis crate engine costs?
$5,700.
Renesis centerhousing:
Obviously one would need a new e-shaft. The whole idea was to get full size
center-exhaust for a "more than 2 rotor" - engine. In this case the "new"
centerhousing dimensions donīt matter, as the e-shaft would be new anyway.
If you donīt need or want the 2+ rotor engine you stick with the base
Renesis anyway....
The Drawing below:
It seems this engine is peripheral everything?
I understand the Mercedes-rotaries, 3 and 4 rotor had one-piece e-shafts and
split bearings (as is common in piston engines).
Is there anything that speaks against this practise in lets say a 2+ rotor
13B or Renesis?
Thomas J.
Probably more expensive.
