Tech talk with Fred Simpson the "Great Engine Debate"

Author: Bill Tsagrinos January 24, 2026 Duration: 1:27:54

There's been a lot of noise lately about engine performance, dyno numbers, and expectations—and instead of adding to the speculation, I brought in someone who actually lives this stuff. This week, I sit down with Fred Simpson for a good conversation on cylinder head technology, porting and polishing, and how all of it really translates into horsepower.

Fred breaks down engine combinations, airflow calculations, and what kind of power you can realistically expect from different motor setups—while also being honest about the limitations he's run into over the years. We also get into camshaft technology and ask the big question: has cam design kept pace with modern cylinder head development?

To round it out, Fred shares his unfiltered take on exhaust systems—what works, what doesn't, and which designs he says flat-out choke an engine. If you're into engine theory, real-world results, and no-BS technical insight, this is one of those episodes you won't want to miss.
