11:1 CR is a decent guideline for old technology.You need to express this when telling someone that 11:1 compression wont work with out a different fuel. New car technology(BMW,Ford) have engines that are 11 and 12:1 cr. All they need is mid grade gas or better.Mazda has 14:1 CR in the economy car line.How is that possible? Mazda also uses 14:1 CR in their economy diesel? How is that possible?

We as hot rodders have to adapt to newer technology.
