That list is a joke. How can they make such general assumptions and publish it. The only thing I agree with is the part about making sure it doesn’t detonate. The rest is bogus. Example, “8.0:1 is the optimal compression ratio”. Even on methanol? Come on. Another example, “maximum rpm 4500-5000”. The highest load the piston sees at the torque peak. That’s when cylinder pressure is highest. I don’t know who wrote that but damn.
