It looks and sounds great.
A response from Shawn to a viewer on YouTube even suggests that pre-production "samples" could be available by Spring, 2016.
But Shawn didn't specifically respond to another question, regarding power gain. The hopes he expressed to me were that his design would offer improved mileage and reduced emissions.

Meanwhile, there's now a web site and Facebook page you can watch for developments.
