I'd be curious about the injection setup needed to get the amount of fuel needed in there for that kind of (short lived) output.
What's the max delivery capacity of a listeroid injector pump? Obviously it can overfuel a bit , or you wouldn't get black smoke at full load and RPM. Could it handle the delivery of whatever fuel's needed when you cram a few extra atmospheres into the cylinder before compression, or would your 40/1 top out at 30 because of fuel issues?
