Ep 78. The Great Blower Cam Debate

The Great Blower Cam Debate is the 78th episode of the fifth season of Engine Masters. This episode delves into a debate that has been raging on among engine enthusiasts for a long time now - which camshaft should one choose when building an engine with a supercharger?

To answer this question, the show's hosts and expert builders take us on a journey through four different supercharged engines, with each engine having a different camshaft. Along the way, they will break down the science behind each camshaft, how they work within the engine, and how they have an impact on the engine's power and torque output.

In the first engine, the team installs a camshaft with less duration, which means that the intake valve stays open for a shorter duration of time as compared to other camshafts. This engine's output is then compared to the second engine which has a camshaft with more duration than the first one. The two engines are run on a dyno to measure their power and torque outputs, and the results are quite interesting, with each engine having its own strengths and weaknesses.

In the third engine, the team install another camshaft - one with a different lobe separation angle than the previous two. A lobe separation angle affects the engine's power and torque delivery, and the results from this engine will offer another perspective on how different camshafts affect an engine's performance.

Finally, in the fourth engine, the team will install a camshaft that has an even larger duration than the second engine. This engine will be run on a dyno to measure its power and torque output, and its results will be compared to the other three engines.

In addition to the science and data, the hosts will provide their own insights and opinions on the best camshafts for supercharged engines. They'll discuss the real-world performance and drivability of each engine, and weigh in on which camshaft they think is the best choice for someone building a supercharged engine.

Overall, The Great Blower Cam Debate promises to be an engaging and informative episode for engine enthusiasts. With real-world data and expert opinions, viewers will gain a deeper understanding of how different camshafts affect engine performance, and which camshaft might be the best choice for a supercharged build.
