Ep 41. Stock vs. Built vs. Boost vs. Both

In Engine Masters season 3 episode 41, the focus is on comparing stock engines to built engines, and naturally aspirated engines to boost-enabled ones. The episode is titled "Stock vs. Built vs. Boost vs. Both", and it is all about finding out which type of engine comes out on top. The hosts of the show take on this challenge by testing out two different engine configurations, one of which is a built engine with a naturally aspirated design, while the other is a stock engine that has been upgraded with forced induction.

Right from the beginning, it is clear that each of the engines has its strengths and weaknesses. For instance, the built, naturally aspirated engine has impressive power right from the start, but it doesn't have much room for growth in terms of performance upgrades. On the other hand, the stock engine with forced induction can be pushed to much higher power levels, but it requires a lot more work to get it there.

To start things off, the hosts begin by running both of the engines on a dyno to get baseline power measurements. They then start swapping parts between the two engines to see how the performance changes. For instance, they experiment with swapping the headers, exhaust, and air intake systems to see which combinations work best. They also look at things like compression ratio and camshaft design to see how they affect the engine's performance.

Throughout the episode, viewers are treated to a wealth of technical information about engine design and performance. The hosts explain the science behind each tweak they make to the engines, showing how even small changes can have big impacts on performance. They also discuss topics like engine tuning, fuel injection, and various other performance upgrades that can be made to engines.

As the episode progresses, the competition between the two engines heats up. Each time one of the teams makes an upgrade, they test the engines out again to see how the performance has changed. The results are sometimes surprising, with one engine coming out on top one moment, only to be surpassed by the other engine in the next round of testing.

One of the key takeaways from the episode is that there is no single "best" engine configuration. Each type of engine has its own unique strengths and weaknesses. For instance, a built, naturally aspirated engine might be ideal for racing applications where top-end power is essential, while a stock engine with forced induction might be better suited for street driving where low- to mid-range power is more important.

Overall, "Stock vs. Built vs. Boost vs. Both" is an exciting and informative episode of Engine Masters that is sure to appeal to anyone interested in performance engine design. By comparing different engine configurations and showing how they perform in various scenarios, the episode offers valuable insights into the science of high-performance engines. Whether you are a seasoned gearhead or simply someone who appreciates the thrill of high-speed driving, this episode is sure to impress.
