Lynn,


Does the Renesis have similar shock-wave issues? Or with its different
exhaust geometry, does it attenuate the shock-wave?

It has no such problem. More similar to a (Gasp) piston engine. The port is
sharp edged, slow opening,
and has a 90 degree turn cast into it. That energy expended inside the
engine shows up as a bit more coolant temp. Even so, a spectacular
improvement.
