You can roughly calculate the VE of an engine if hp is known=20 with:

VE =3D 5600 X HP divided by (RPM X Displacement in cubic=20 inches)

This=20 would indicate that the rotary, with a VE of 1 would require a=20 displacement of 160 cu in to get a HP of 180 at 6300 rpm or 200 at 7000= =20 rpm.

So=20 what is the deal on the 1300 cc? that is about 80 cu in. abou= t=20 half what would be required to produce the HP we hope to=20 get.
