Dan Gurney's Moment-Cancelling 4-Stroke tandem-twin engine

First saw this new engine (MC4S) spotlighted in Feb'16 issue of Car & Driver, then found this earlier on-line article:

Can Dan Gurney

The 'interesting' aspect (for me) was the leap from 141 hp to 262 hp with his change from straight intake to optimized tapering intake...that's an 85% increase in power...from 110 cid/1.8L and only 9.5:1 compression ratio!

This is his (Dan Gurney's) website on the MC4S engine with simulation data: http://www.momentcancelling.com/simulation-data.php
