I stumbled upon this video of the owner of Sprit Engineering discussing the SE-1. Of particular interest to me is the portion of the video about establishing TBO of their engine. That portion starts at about the 25:40 point. I found his comments about burning 100LL, particularly the part about exhaust valve cooling, interesting.
Here is a link to the video: Spirit Engineering Spirit SE-1 - 2026 SUN 'n FUN MOSAIC Day.

I love everything about the way he talks about designing airplanes. I want to buy an SE-1 just because I believe in what they’re doing so wholeheartedly.
Reinventing the steel tyred wheel, is hardly a progressive move forward.
Next thing, you will give up your car in favour of a horse drawn buggy.
Nostalgia has its place. In this case, nice warm/sunny days, at low altitude, where the ground based proletariat, can admire this fake blast from the past.
