This one rotor version on the other hand is easy to do. Use a peripheral
port and an external oil pump. The rotor housing is still liquid cooled
with modifications to allow the water to flow from chamber to chamber.
New water inlets and outlets are drilled and tapped into the rotor
housing. Cold water into the spark plug area first. The end housings
have simple steel wear surfaces held in place by the rotor housing
and the steel front and rear main bearing holders.

Paul,
I know your talking about a 1 rotor here but would milling out the ports
have a +ve effect on a 2 rotor.

Why I ask is that when you put in a PP you plug up the only completely open
passageway in the inlet area and I was wondering if they were all open-up
would that benefit the cooling.

On the other hand ( I thought) they may be partly closed to force the
majority of the coolant through the channels adjacent to the combustion
area.

Question 1: "milling out the ports have a +ve effect on a 2 rotor" I don't follow you on
this George. Milling out the side ports? Yes that helps up to a point.

Question 2: I don't follow you on this either. If you are talking about
milling out the partitions in the rotor housing I don't think that
would help the cooling with the stock two rotor engine.

Yes they are closed but we are talking about an entirely different way
of cooling the rotor housing with the one rotor configuration.
The one rotor with air cooled end housings would cool the rotor housing
more like this NSU cooling scheme. BTW note the two stage peripheral port.
