We will have to do another manifold for the RX8 engine with yet larger
runners for peak torque/HP at 7800 RPM assuming the use of a 2.85:1 psru.

Paul, something I wonder about, has anyone direct injected the rotary?
For our purposes it would seem almost ideal in that we could make a
simpler variable length intake or peripheral port and inject fuel on the
plug side away from the exhaust heat. Bill Jepson

There has been a lot of work done with that. Wankel Gmbh had one running
on diesel fuel with direct injection. Curtiss Wright, John Deere, RPI
too.
