For the record 12.13:1 compression is 1.018"% over the 12:1 limit. That would be about a 5hp advantage, and about a 1% advantage on total score.
Randy was almost 5% ahead of the next engine.
This is a great example, of why you always need to check everything on your engine. Measure, measure again, and when you're sure you're correct, measure one more time.
I learned from some of the greatest engine builders of their day. There was no magic to what they did. I figured out pretty quickly, that their "Speed secret" was being meticulous. They measured everything. If there wasn't a tool to measure something correctly, they made the tool to measure it.
