Never enough.... Were still talking street cars, right? Are any of these points invalid? Carter put an altitude compensator on the later Thermoquads because they thought it would help high altitude AFR's. Feedback carburetors were developed to tighten emissions by monitoring and increasing the combustion percentage. EGR allowed engines to run cooler and decrease NOx. All of these were evolutionary to the original carburetor, and all of these are now controlled in a dynamic fashion with EFI. How about a race profile with an optimum line lock, rev limit (even shift capabilities) or nitrous window with built in retard based on RPM...and then a street profile that doesnt include any of this track stuff? You can have the best race tune and the best street tune literally at the touch of a button on a screen of a tablet or even your phone. A NASCAR spare motor doesnt make a good street motor.
