Ep 65. Engine Personality Test: Camshaft LSA Explained

Engine Masters season 5 episode 65 focuses on the camshaft LSA (Lobe Separation Angle), which is an important aspect of engine building and performance. The episode is titled "Engine Personality Test: Camshaft LSA Explained," and it features the Engine Masters team testing out different camshaft LSAs and examining how they affect engine performance.

The show begins with an explanation of what the camshaft LSA is and how it affects engine performance. The LSA is the angle between the centerlines of the intake and exhaust lobes on a camshaft. A smaller LSA (less than 110 degrees) will produce more high-end power, but will sacrifice low-end power and throttle response. A larger LSA (greater than 110 degrees) will produce more low-end power and throttle response, but will sacrifice high-end power.

The Engine Masters team then proceeds to test out three different camshaft LSAs: a 108 degree LSA, a 114 degree LSA, and a 118 degree LSA. They use a 5.7 liter LS engine and install each camshaft, then test it on the dyno to see how it affects power and torque. They also examine the engine's throttle response and overall "personality" with each camshaft.

Throughout the episode, the Engine Masters team explains the science behind each test and breaks down the data for viewers to understand. They also offer insights on how different LSAs can be used in different types of engines and for different purposes. For example, they note that a larger LSA might be better for a street car that needs good low-end power and drivability, while a smaller LSA might be better for a race car that needs more high-end power and speed.

Overall, "Engine Personality Test: Camshaft LSA Explained" is a fascinating and informative episode for anyone interested in engine building and performance. It provides a detailed look at how different camshaft LSAs can affect an engine's performance and personality, and offers valuable insights for engine builders and enthusiasts alike.
