Power Driven Podcast

In this episode of the Power Driven Diesel Podcast, Will, Myer, and Todd dive deep into everything cylinder heads—what makes them tick, what causes head gasket failure, and how to make serious horsepower. Whether you're just trying to keep a head gasket sealed or chasing four-digit horsepower, this episode covers it all. The guys break down the real differences between head stud materials, head bolts, O-rings, and fire rings, and share hard-earned knowledge from years of testing, tuning, and racing. Todd shares dyno stories and real-world examples, while Will and Myer go full nerd on airflow, valve spring pressures, fire ring groove design, and why coefficient of discharge actually matters. The team discusses the myth: “boost blows head gaskets” and they then explain why torque is the real head gasket killer. You’ll hear about their CNC porting journey, how they’re pulling huge gains from factory castings, and why a properly ported head is one of the only upgrades with no downsides—more power, better spool, improved drivability. Whether you're building a street truck, tow pig, or race rig, this episode is your one-stop-shop for understanding the top side of your engine and how to make it bulletproof.

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?

The Desert Diesel Nationals in Phoenix was an all-out diesel showdown, and the Power Driven Diesel crew was in the thick of it. Todd, Will, and Myer break down everything from record-breaking passes to the wildest burnout contest the event has ever seen. With thousands of spectators, packed pits, and some of the fastest trucks in the country, this event brought back the old-school diesel racing energy.

Todd hit a personal best 60ft time of 1.27 seconds, proving his truck is dialed in, but transmission issues cut his weekend short. Will locked in the 590 class victory, running smart and staying consistent to take home the win. Myer, despite some solid passes, learned firsthand how crucial reaction time is in a close race.

The burnout contest stole the show, bringing an Australian-style burnout pit where trucks whipped around, roasted tires, and put on a wild display of power. Will’s junker truck disappeared in a cloud of smoke before flames ended his run, while Myer’s new build ran into mechanical issues before he could really throw down. The contest was a fan favorite, proving that burnouts belong at diesel events.

Beyond the racing and burnouts, the event was packed with vendors, insane builds, and non-stop diesel talk. Whether it was discussing turbo setups, tuning tricks, or suspension tweaks, the pits were buzzing with knowledge and inspiration.

If you missed this one, don’t worry—more races are coming, including Tulsa in May, Billings in August, and World Finals in Texas this September. Tune in for the full recap, behind-the-scenes stories, and everything you missed from one of the best diesel events of the year!
