hi..again! I was just recently reading about Mazda Wankels Thermostat
instead of taking it off why not try a Moroso Water Outlet Restrictor
and they are cheap!!! like 7 or 8 bucks also you can make them or
machine them you can get them at www.summitracing.com,has
<http://www.summitracing.com,has> any one tried reduction pulleys? like
the one in the above pics from www.xtremerotaries.co
<http://www.xtremerotaries.co> they are made for high rpm engines it
will help with cooling and reduce rotating mass freeing up some HP!!!!
has anyone tried electric water pump? im just curious on this one and
also it will free some more HP!!!....hope I helped on this one!

You want to increase water flow in an aircraft engine and not restrict
it.

Same goes for an electric water pump.
The water pump in a rotary consumes only 3 HP.
Don't use an electric pump in an aircraft engine.
