Hi Jerry,

for your airplane, I don't think you have to worry about power, all you =
have to worry about is weight. In order to meet 200lb FF, a bare engine, =
say long block, should be under 100lb. My 12A based single is 90lb =
giving a FF of 170lb. The 701 probabely will only require maybe 50hp at =
cruise, and the utilization of every hp over and above that depends very =
much on a proper prop dimensioning and setting. Especially on take off =
distance, the heavier, stronger engine does not give you an advatage, =
generally speaking. It mostly makes you climb better at higher airspeed.
I have a friend with an AVID running a Rotax 582 with 65hp. His take off =
distance is essentially the same as mine with 100hp, however, my =
airplane is 15-20% heavier.=20
FWIW.

  George,  those hp claims seem wildly exaggerated to me.  I have never =
heard anyone claim  200 hp for a two rotor street port at 7500 rpm.  But =
I hope they do turn out to be true.  I accept the Power Sport numbers of =
around 107.5 hp per rotor with a 1.5  i.d. p port.  Perhaps if they had =
turned 7500 rpm they might have made somewhat more hp.  According to =
calculations done for my original p port, a 1.5 i.d.port will flow 8000 =
rpm just fine.   Side ports are relatively terrible when compared to a p =
port. I don't think their comparable size has relevance.  Jerry

        Jerry,
        I'm trying to compare the carb inlet area to port or P-port =
areas.
        Standard Port area 32 deg ATDC to 50 degree ABDC =3D 1.18 sq " =
each side (x2 =3D 2.36sq")- using the front and back housings only.
        ?
        A street port will be 1.5sq" x 2 =3D 3sq"
        .
        A 44mm P-port =3D 2.35sq"
        A?42mm p-port =3D 2.14sq"
        A 40mm P-port =3D 1.94sq"
        A 38mm P-port =3D 1.75sq"
        So you see a side port on a single has more port area than a =
small P-port.
        Perhaps the velocity will make up for less area.
        The street port is bigger again at 3 sq" - this equates to 50mm =
port.
        ?
        The standard port gives about 100 hp, the street port about =
130hp each rotor.
        I wouldn't want to choke down the port areas with too? =
restrictive inlet carby?area. I can't see how a 38mm will cut the =
mustard when your own calculations suggest 1.6 P-port =3D 42mm sq".
        ?
        In reality I'm only looking for 130HPat most, if I can get that.
        ?
        I can run a 41mm ID SS tube p-port with a 42mm Carby ( and hope =
velocity makes up the difference) Or I can run with two 1.5 street =
ported side ports 3 sq" with two smaller carbs, perhaps 2x32mm.
        ?
        BTW street ported 13B has been dynoed to 264hp can't remember =
the RPM - it might have been higher than what we run.
        More confused than ever!
        ?
        Does anyone know the IO/IC and size and HP?of the factory =
P-port.
        ?
        Lynn, does the timing given, calculated by the rotor uncovering =
and covering the port, or the side seal uncovering/covering the port =
opening?
        I was thinking the RX8 rotor will be slightly different (bigger) =

          George,? maybe I have the wrong idea, but I don't understand =
