Unless the rotors have been changed, the Renesis manual says they're 10/1.

    Yeah, I  know, only 16 hours.  Confession time.  I'm much more a 
builder than a flier.  I'm starting to enjoy  flying the 8, but I really 
like building!  Going out to the hanger and spending the evening, with a 
problem in mind to solve and running solutions through my head, in 3D 
and rotating and changing it (like a mental CAD program) and then 
figuring out the practicalities of building it with available materials 
and skills or searching for other materials and others who have the 
skill and tools.  I miss waking up at 2:30 am  with a possible solution, 
writing it down so I can go back to sleep and then trying it out the 
next day.  These night time solutions aren't always correct, but they 
almost always lead me on to the next step and the next, etc.  And then 
building the thing.  Most things I built 3 times before I got it right.  
When it's right it's RIGHT.
    Then there is my personality defect.  The better is always at war 
with the good.  Defiantly a builder thing and not a flyer thing.  It 
feels great to be new and better and different. And that is just the 
outcome.  The process is fun too.  To bad it's a never ending cycle.  
Not to mention there is a former Tomcat instructor out here with a clip 
wing Super RV-6 with a dynoed 317 HP IO-540 in it, doing 3000 ft/min on 
climb out.  Not to mention the huge C.S. club he has out front.  I'd 
really like to have something approaching this power and have it done 
with finesse and expertise rather than money and brute horsepower.  I'm 
not sure if the rotors in the Renesis are 9.7 or 10.0 to 1.  My paper 
work from Bruce says both.  I think I need to talk to him about whether 
the engine will handle it or not.
    This whole thing is a thought experiment.  I figure that to get the 
NA working better I will have to build a new exhaust and intake.  Build 
it less fancy and more like Tracy's, paying more attention to the inside 
welding and reducing flow disturbances.    If I'm going to all that 
work, perhaps the thing is to take it to the next level, turbo or even 
20B.  Major advantages and disadvantages with both routes.    Anyone 
other there have an extra Renesis 4 port lower aluminum intake manifold 
they want to sell?
