Ep 4. Exhaust Header Bash! Testing Power Loss From Dents

Engine Masters is back with an all-new episode named Exhaust Header Bash! Testing Power Loss From Dents in season 1. In this episode, the team of skilled mechanics and engineers explore the common myth about dented exhaust headers.

The episode kicks off with host David Freiburger explaining that many enthusiasts believe that dented or damaged headers can significantly affect engine power. However, this belief has not been scientifically proven, and that's where the Engine Masters team steps in.

The team begins by testing four different exhaust headers that are identical, except for the dents. They want to examine their impact on engine power. They then mount the headers on the engine dyno and fire up the engine for testing.

To ensure accurate results, they test two engines in two different states: one with dented headers and one with perfect headers. Both engines were run multiple times, and the results were averaged out to eliminate any discrepancies.

The results of the tests are surprising. The team found that the dented and perfect headers performed similarly, with only marginal variations in power and torque. The tests discount the myth that a dented header will significantly reduce the power output of an engine.

To add to the knowledge gained from the tests, the team also explores the different tubing sizes and shapes on the headers and their effects on engine power. They tested a set of headers with oval-shaped tubing and compared them to standard round headers. The oval-shaped headers produced more power in the low-rpm range than the regular headers.

The team also tested different header coatings, including plain steel, ceramic, and nickel. They found that the plain steel headers rusted quickly and reduced the power output of the engine. The ceramic-coated headers proved to be more durable and kept the engine running efficiently. The nickel headers were the most expensive but provided the best performance and durability.

Throughout the episode, the team discusses their testing procedures and offers insightful tips on how to get the most power out of exhaust headers and increase engine performance. They talk about the importance of the header design, size, and shape, and how the header's performance is affected by the engine's design and tuning.

The show concludes with David Freiburger summarizing the results of the tests and how they debunked the myth that dented headers significantly reduce engine power. The team also provides helpful tips on how to choose the right headers for a particular engine and get the best performance out of it.

In conclusion, Exhaust Header Bash! Testing Power Loss From Dents is an informative and exciting episode of Engine Masters. It offers valuable insights into the working of exhaust headers, their impact on engine power, and how they affect engine performance. The show is a must-watch for any enthusiast looking to maximize engine performance and get the most out of their vehicle.
