So to reiterate, it seems like you can do almost anything to these engines as long as they run smoothly and don't exceed the temperature limits.
 
Am I close??

I also set the prop for 2300 on down wind. This provides me with enough rpm for a comfortable go around without as much prop breaking effect.

What Bill said. With the super charger I run 4800-5200 in cruise. 12.5 F/A for take off and climb.  This provides cooler EGT's.  15.8 f/a for lean cruise. Cool EGT's.  I stay away from 14:7 f/a / peak EGT's.  

The EC2/3 have a programmed rpm limit.  I think mine is 7500.

Rich,

 

If your prop will allow it, I take off at 7100 rpm, best power, WOT.  After I get 6-700 ft, I dial the rpm back to about 6500, still best power and WOT.  For cruise about 5800-6000, leaned about 50 degrees below peak, still WOT.  The only time I adjust the throttle is during the approach to landing, otherwise WOT.  Adjust power with the rpm.  Temp is the critical factor if you don’t yet know how the setup cools.  I have a red line of 220 on water and have never seen my oil above 200.  On a really hot day I can see the temp hit 220 by the time I am reducing power.  The power reduction and increase the speed from 100K to 120K and it cools right down with my setup.  I see about 180 water and 160 oil in cruise.

 

If you have a pusher be aware of your pitch on rotation and landing.  How much clearance do you have for the prop?

Thanks all, for the replies,

 

I can rotate a little more easily now.

 

Because I am a pusher (that doesn't sound exactly right) My in-cabin noise may be less than with a tractor, and because the aircraft is glass perhaps it will be a little quieter. In any case, because I am a little (?) older I may not hear the noise as acutely as younger eared people.

 

So I won't worry about the throttle setting and keep my TO RPMs at or below the Renesis recommended stats.

 

That still leaves the mixture question unleaned.

 

Any thoughts of what to do with the mixture????

 

Thanks again,

 

Rich
