If you have ever been told, “That’s just how piston engines work,” this episode of Aviation Masters might make you raise an eyebrow and then start asking more questions.

In this episode, host Mike Busch sits down with George Braly, one of the most influential (and unapologetically analytical) minds in modern general aviation.

Braly is an inventor, trial lawyer, entrepreneur, and the co-founder and chief engineer of General Aviation Modifications, Inc. (GAMI)—the company behind GAMjectors, Tornado Alley Turbo systems, and the FAA-approved high-octane unleaded avgas G100UL.

This is not a surface-level conversation. It is a deep, technical, and refreshingly honest look at how innovation actually happens in aviation and why it is often resisted at every step of the way.
