El= sewhere on this same site he claims”

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

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

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

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