Interesting, backstreet mechanics

What's the consensus, is he a crank or someone who had made a genuine breakthrough but no one want's to know due to the "not invented here" syndrome.

Can't make up my mind personally. His invention, on the face of it seems to make sense. But no one has bitten his arm off as you'd expect if it truely worked.

Not one single dyno graph to backup the power/torque results.

Not quite true. If you read the article and follow some of the links you'll find that Briggs & Stratton donated an ancient side valve engine for testing.

This was tested on an official dyno and results were produced. The result was a significant (20% -?) increase in fuel economy, but no improvement in emissions. There was a reduction in exhaust temp and engine running temp too.

I'd agree these results are inconclusive but at least show promise.

The cynic in me says that if you do anything to a Briggs & Stratton side valve engine you'd get an improvement, but at least these tests were carried out in a scientific manner so should have kept conditions for the test engine and benchmark engine similar.
