But it occurs to me that it would be a lot easier to just = park the plane and the RX8 side-by-side and say "Isn't it amazing that they = have basically the same engine!" But I guess that wouldn't be much fun.

Today was my second flight since solving = my voltage fluctuation issue and the engine sounds so good I even took off = my headset before shutting down just so I could listen for a while. It = will idle below 900, but I put the stop at 1200 as that's where it sounds = best. Solving that issue has allowed me to run much leaner, the mixture = setting went from 12:00 for best idle to 8:00. Fuel burn is of course down somewhat, and EGT's are about 40 deg cooler. I also made a new, larger and smoother cowl air outlet without the cowl = flap (see picture). It actually turned out better than it looks - the last = layer of micro made some drips that need to be sanded. Between the new cowl, leaner mixture, and cooler OAT my coolant temp are down. I am allowing myself more MAP on climb out at slower speeds. I = can now cool 32" MAP in a continuous climb as long as I keep the speed above 120kts. Today max temps were 160 oil and 180 coolant. This is still a rather anemic climb rate of 500FPM on the VSI (RPM is = about 5000). Come to think of it - it sure seems like I am climbing closer to 1000+ FPM. Will have to do some timed climbs.
