****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

Hi Guys;
   A few months back somebody posted a link to a video shot from the back of a
jetboat as it accelerated at a phenomenal rate. I can't find it in the
archives, but I'd like to get it again. Anybody have it?
