Safe compression ratio?
Ok what's the highest compression ratio you can hit with a stock engine before needing reinforcement?? I was looking on line about ethanol and other fuels like it, and they say that if you can hit like 14.5-1 cr you'd get better FE out of them then with gasoline but I've been told that if you did that to a stock engine you'd blow the pistons out the bottom or else destroy your main bearings really fast. Any ideas??
