James, 

 

My intent is just to normalize to sea level.  The elevation here is 7200 ft and density altitude is often 10000 ft or more. I take the MAP slightly above sea level to be sure I'm not pushing the system's limits.  The turbo is capable of more boost than this.

Steve,

37 inHg is about 18+ psi absolute, so nominally around 3 psi boost above sea level pressure?  Just curious.  Nice you can get that at 8000 feet.  Do you keep it that low for reliability and longevity?  I have heard the Renesis cannot take as much boost as the rotors have less squish space for boost, so maybe that is why?  Or is that as far as your turbo is able to go?

Cool to see the scientific approach on these babies.  Some day when I get my rotary project underway, I plan to do the engine test stand approach.  Seems like the way to make sure everything works properly before risking life and limb!
