Pe,
What's the possibility of getting my hands on a few containers of the oil you're using? I'm in the middle of more testing and I like very much what I see, especially with the method of running you described.
Pat,
I don't know if this has been mentioned yet (I'm not wading through 7 pages just to check), but the short bursts of power method of break in is used all the time in the world of roadracing motorcycles and works well to set the rings. Many tuners will use a dyno for initial break in runs, doing something like 3 runs (all at full throttle) to 70% of redline, then 3 runs to 80% of redline, then 3 to 90% and so on. After around 8-10 hard pulls on the dyno, the engine will develop close to it's full potential with the last couple of percent coming with some track running time. Total dyno time to seat the rings is only a few minutes worth of full throttle running.
Here is a website with a lot more info on the running in process and a bunch of other 4 stroke porting stuff. It looks wacky, but the info is sound despite the presentation:
