****Hi Todd, I lost the plot lately with all the 'risk analysis'  going
on, sorry for the delay.
I am the guy who is interested in the" radial look" for rotaries
.
The website you need is    Xtremerotaries.com  ; they made the boat
engine.  I have visited the factory:   'A1' engineering shop !  This is
the company that displays at 'Sevenoaks" on occasion. Their engines
have held record times in drag and race cars in recent years in AUST
and in the USA..

If you want to talk EWPs, I have an ear for you.   Craig Davis is an
Australian company, I know them from 30  years ago. But beware! their
products come from "Anywhere"
  The problem  with Craig Davis pumps is not capacity, but with
sustained output.  Don Dunbar and I, did some tests last year on the
EWP. The output is OK, but there was a problem with reliability. The
racers say that they change them out every 8-10 hours or so. Some pumps
do not even make 4 hours!  The electric  motor burns out!
With the new RX8 engine and water pump in mind, it seems to me that RX8
technology has left this problem behind. BR, Dave McC
