Ep 4. The Throttle-Body Throwdown!

In the fourth episode of season 8 of Engine Masters, titled "The Throttle-Body Throwdown!", the crew sets out to find the ultimate throttle body upgrade for your engine. They start by explaining what a throttle body does: it controls the amount of air going into your engine, which can affect performance and efficiency. They also explain that upgrading your throttle body can help your engine breathe better and make more power.

To test out different throttle bodies, the team uses a 600-horsepower LS3 engine on a dyno. They start with the stock throttle body and then swap it out with various aftermarket options to see which one performs the best. Throughout the episode, they explain the differences between the different designs and materials, such as aluminum vs billet, and electronic vs cable throttle bodies.

Along the way, they encounter some challenges and surprises. For example, one of the throttle bodies they test doesn't fit the LS3 engine without modification, so they have to decide whether it's worth the hassle to make it work. They also find that some throttle bodies are better suited to certain engine setups, so they have to adjust their testing accordingly.

As they go through the different options, they use their experience and knowledge to evaluate each one and explain their findings to the audience. They also share tips and tricks for installing and tuning throttle bodies, such as using a datalogger to fine-tune your settings.

By the end of the episode, they've tested six different throttle bodies and have a clear winner. They wrap up by summarizing their findings and providing some advice for viewers who are considering upgrading their own throttle bodies.

Overall, "The Throttle-Body Throwdown!" is a fascinating look at an often-overlooked component of your engine. Whether you're a seasoned mechanic or a beginner, you're sure to learn something new and come away with a better understanding of how to get the most out of your engine.
