The average CHT went from 256F to 273F (got that number wrong too), so the increase in CHT was only 17F, rather than 26F. Still, it points out that the CHTs are actually cooler at LOP.

And how much improvement would you get with avgas?? 100LL costs about double what 93 octane auto fuel costs here now. I guess I burn mogas because I can, it's less expensive, and I do a lot of flying every year. Although I'll be the first to admit that auto fuel has a increased vapor lock tendency and WW would be quick to say an increased likelyhood of lighting off in a crash, 100LL does work a little better when it comes to leaning (the engine is happier running leaner), but certainly nowhere near enough to make up for the double price..
