Paul,

   On the RWS web site this page showing your intake castings
   (http://www.rotaryaviation.com/intake_manifold1.htm) is
   posted.  Do you have one piece castings for a PPort
   design?

   I am starting with a 89-92, series 5, FI, non-turbo. motor
   with the goal of getting ~300 Hp at 9000 rpm for use in a
   BD4c or RV10.

   Thank you;

   JD Grubbs

   You will need over 3:1 in your gear box to get 300 HP at 9,000 RPM
   Most props bottom out at 2700 RPM.

Paul,
Can you still supply these intake castings?  Have you made an intake
casting for the 20B?  As you can see from my previous post tonight, I'm
trying to work out options for my intake manifold.  If you don't have a
intake manifold casting for the 20B, those runners might be just what I
need to fab my own.
Don

No. Sorry I forgot to answer that question. I am all sold out.
I never made a casting for the 20B. I think you will have to fab
your own. I just had a conversation with Ed Klepeis today in the engine tent
on that subject. He claims he can make them out of the stock casting by cutting
them down and welding on tubes. You might take him up on that claim.
Edward Klepeis <techwelding@comcast.net> He will be here at Sun n Fun
for a week.

For the p-port you don't need castings. Two or three  180 bends out of 2 inch OD
.065 wall tubing is all you need.
