Senior Project
Kirby Kennedy grew up around street rods in his hometown of Selmer, Tennessee. His father, David, had several rods and even operated his own shop. Kirby hung around Kennedy’s Kustom Auto Shop and helped with many of the projects. He also learned many of the required skills to build a rod along the way. Once Kirby reached high school, he knew quite a bit about the history of hot rodding and had developed a fondness for traditional hot rods. His school required each graduating senior to complete a project before they reached graduation. While only a sophomore, Kirby decided to build a traditional-styled hot rod.

Why You Should Be Running E85
E85 isn’t just for race cars. It’s a powerhouse fuel that’s widely available and seriously underrated. Here’s why you should be running it in your GM truck or SUV:
- More Power: E85 has an octane rating of 100-105, allowing for more aggressive timing and higher compression—aka more horsepower.
- Cheaper Fuel: E85 is usually way cheaper than premium gas, meaning you save at the pump while making more power.
- Lower Engine Temps: Ethanol burns cooler than gasoline, reducing wear and extending engine life.
- Cleaner Emissions: Less carbon buildup, fewer greenhouse gases, and a happier planet.
- Detonation Resistance: The high octane rating helps prevent knock, making your engine run safer and stronger.
- Renewable & Sustainable: Made from corn and other biofuels, reducing dependence on fossil fuels.
Advanced Fuel Dynamics: Born from Frustration, Built for Performance
Back in 2014, a tuner got fed up with E85 tunes that never seemed quite right. The problem? Pump E85 is all over the place when it comes to ethanol content, and a fixed tune can’t compensate for that. The solution? A real flex fuel system that constantly adjusts in real-time—thus, Advanced Fuel Dynamics was born. Since then, they’ve been cranking out battle-tested fuel solutions for street, strip, and dyno warriors alike.
