Choosing the Best Turbo for Your Cummins

Описание: Let's talk about towing and hot street performance turbos!

Turbo sizing is one of the most common (and misunderstood) topics in diesel performance. Whether you’re replacing a worn-out stock turbo or upgrading for more power, the right choice depends on your horsepower goals, driving style, and how you use your truck. In this episode of the Power Driven Podcast, we break down everything you need to know about single turbo setups, from common upgrade mistakes to real-world performance insights.

One of the biggest misconceptions in the diesel world is that bigger is always better. While a large turbo can support more horsepower, it often kills low-end response, making your truck sluggish—especially if you tow. We discuss the differences between drop-in replacements, S300s, and S400s, explaining when each one makes sense and how to avoid the dreaded lag-to-power ratio mistake. We also share our personal turbo experiences—what worked, what didn’t, and the lessons we’ve learned from testing everything from Holset HE 351-based turbos to massive Garrett GT55s.

For those looking to upgrade their work truck from the stock turbo, we cover the best options for 300-500 horsepower and the ideal single turbo setup for 600-700 horsepower. We also dive into why compounds almost always outperform big singles for a street-driven truck. Plus, we break down how to calculate turbo airflow and horsepower potential, so you’ll know exactly what to expect before making a change.

By the end of this episode, you’ll have the knowledge to choose the right turbo for your goals, avoiding costly mistakes and maximizing your truck’s performance. Need help picking the perfect turbo?
