[QUOTE="Matt Whiting"] Sure it is. You said "There is no substitute for cubic inches." There are lots of substitutes. Here are just a few: 1. Turbocharger 2. Supercharger 3. Nitrous Oxide injection 4. Higher compression ratio These are all ways to increase power without increasing the displacement. Maybe you have a different definition of subsitute.[/QUOTE] They are good ways of getting the most of the available cubic inches, but no matter how many of your add-ons you add, more cubic inches will still make them more powerful.
