Don't take this wrong. I'm not trying to shake anybody up. I would
LOVE to see this engine work the way they claim it works.

But I have calculated the Brake Mean Effective Pressure of this
engine using a couple of possibilities, based upon the stated engine
displacement and stroke.

BMEP is a tool used by engineers to compare the horsepower
output of engines of varying sizes and designs.

If the stroke of the engine is really 75 millimeters, and the displacement is really 1086 cc, the engine would have to have a
mean effective operating pressure though the power stroke of
760.42 psi.

No internal combustion engine known to science has this much
BMEP.

So I recalculated BMEP, assuming that the 1086 cc was the displacement of ONE of the eight cylinders. That would mean the
whole engine would be 530 cubic inches.

159 horsepower at 2500 RPM is believable for an engine that big.

The calculated BMEP comes out to 253.88 psi. That is still too
high to be credible.

I would have to believe that whatever method is used to convert reciprocating motion to rotating motion is so much more efficient than a crankshaft that it accounts for this improvement.

A turbocharged Indy car only has a BMEP of about 220 psi, and
it has to turn 12,500 RPM to accomplish this feat.

I know you won't sell your shares based on anything I say. But if
anyone finds out any new information on this engine, I would love
to hear it.
