   Two 750cc injectors in the housings probably won't not deliver
   enough fuel
   to get to 300hp. on take-off  Especially if the fuel is ethanol.
   This was
   the main reason (4 injectors per manifold) I considered a horizontal
   slide
   throttle and cast aluminum elbow with two more injectors. That and it is
   easy to encased the lower injectors in a box that goes from the
   housing to
   the slide throttle.

   Perhaps lost wax for a few units is possible.  Collecting beer cans
   now..

   The direct injection takes max advantage of the alcohol's
   unique ability to cool off the charge. It also insures that
   no un burned fuel goes directly out the exhaust down
   past the rotor face.

   There is nothing wrong
   with four injectors up there. Point them in horizontally.
   RB  did that on the land speed record 3rd gen RX7
   three rotor with three turbo chargers along with an ice
   water intercooler. (268 MPH)

Doug,
Not wanting to burst your bubble Doug, but if I remember correctly you
were interested in long distance travel? The R85 ethanhol blend will
shorten your range at least 20%. There just aren't the BTU's/pound in
alchol. It will burn cleaner but it will burn a bunch more fuel. The
rotary will suffer even more than a piston since you can't get the
compression beyond 9:1  NA. A turbo would be more efficient as Paul
mentioned.
