if you start really researching all motor builds. not just honda, but the whole science and art behind it. I think you'll come to the conclusion that static compression ratio is like hp. just a number. when you calculate your cam overlap, stroke, cylinder pressures, flowbench numbers, piston shape and everything else involved you'll get the dynamic compression ratio- the number that matters to the engine, and makes it prone to pinging. you can find engine builders have created some 16:1 CR B16s that run on pump gas....
