Did a ton of high boost and nitrous testing this summer. Last weekend ran 38psi and a 150 shot of N2O. Car ran great with no miss-fire. This was on GEM 40 (40% methanol, 38% pump 92 gasoline, 22% ethanol) with zero knock.
The only negative thing at this HP is I'm going to have to build a type of heat sink to pull away some heat from the pre-chamber. It was too hot for my liking.
Been working on the center electrode size this summer also. Since the spark plug has no ground electrode and utilizes the pre chamber outer case as the ground electrode. I have three different types of center electrodes. One is for light load FE (extreme lean), the second is for high load HP (lean/performance) and FE, and the third is for extreme high load performance (rich high performance only).
One good thing that came from the high heat pre-chamber issue is it opened up a lot of ways to build a performance pre-chamber.
