Lean vs Rich: How Fuel Mixture Really Affects Power (Dyno Tested)

How does air-fuel ratio (AFR) actually affect engine power? Instead of guessing, repeating rules of thumb, or arguing on forums, I put this car on the dyno and tested it — step by step — at different air-fuel ratios, from rich to lean. In this video you'll see: Real dyno pulls at multiple AFRs How horsepower and torque change across the entire RPM range How small AFR changes reshape the torque curve The tradeoff between power output and safety margin How this data can be used to build a fuel curve instead of relying on a single flat AFR — and why you may not want to This applies to carbureted engines, EFI, motorcycles, and any internal combustion engine. The principles are the same — even when the hardware is different. NEXT VIDEO: We'll run the same type of controlled testing with ignition timing to show how spark advance reshapes the power curve.
