I have driven my car at high speeds for extended times. I'm not talking about theories, guesses, calculations, or dynos. I'm talking about seat time bud.
Let me see, you have no drag racing experience by your own admission, so let me ask: what is your high-speed-driving experience? Have you ever driven a car to 200mph? Do you honestly believe that an engine is all it takes to get to 225? If you haven't actually done it than you probably can't be convinced.
