• Is More BOOST Always More POWER? Diesel Myths Exposed

  Welcome back to the Power Driven Podcast—this time broadcasting straight from the shop floor! In this special “Diesel MythBusters” episode, the team dives headfirst into some of the most common (and controversial) diesel performance myths that float around forums, social media, and garage talk. If you’ve ever asked yourself, “Does more boost always mean more power?” or “Do 215 pumps really retard timing?”—this episode is your definitive guide to separating fact from fiction.We kick things off with the myth of dual-feeding P-pumps and whether or not your 12-valve needs it. Spoiler alert: probably not, unless you’re pushing serious horsepower. From there, we explore the science behind boost, efficiency, and how drive pressure really impacts head gaskets. It’s not just about throwing bigger parts at your build—understanding how airflow, fuel delivery, and timing interact is key to dialing in performance and reliability.The conversation heats up with a deep dive into Speed of Air pistons—those dimpled marvels generating buzz across the diesel industry. Are they the future of combustion efficiency or just expensive snake oil? The team weighs in with real-world experience, engineering insight, and a hefty dose of skepticism.We also take on the age-old air-to-air vs. water-to-air intercooler debate, breaking down the pros and cons in terms of temperature management, power gains, packaging, and complexity. Plus, we unpack whether aftermarket intake horns actually add horsepower—or just dress up your engine bay.As always, it’s equal parts technical knowledge and real shop banter. Expect laughs, a few friendly roasts, and a whole lot of diesel talk you won’t find anywhere else. Whether you’re building a 1,000+ hp race truck or just tuning your daily tow rig, there’s something in this episode for every diesel enthusiast.Stick around to the end as we address the myth that performance upgrades always kill fuel economy—plus, why injector size might be hurting your horsepower more than helping it.

• How to Build a Real 500HP Cummins

  This is one of the most common questions we get at Power Driven Diesel. What does it actually take to hit 500 horsepower with your truck? In this episode of the Power Driven Podcast, we go step by step through each Cummins platform. From First Gen to Common Rail, we cover what it takes to make that power and keep the truck usable.We start with the early trucks. If you have a First Gen with a VE pump, 500 horsepower on fuel only is a tall order. Most guys end up swapping to a P-pump to get there and still have some reliability. For 12 valve trucks, it is a doable goal with the right combination of fuel, air, and timing. We lay out what size injectors, delivery valves, and turbo it takes to make it clean and strong. We also talk about the difference between a street build and a tow build, because those are not the same thing.Moving on to the VP44 trucks, things change a bit. Some of these pumps hit a wall, especially the high output models. We go over tuning boxes like the Quadzilla, why lift pump pressure matters, and what it takes to make real power without hurting drivability. If you are running a VP truck, this section will save you time and money.Then we get into Common Rails. If you have an 03 to 07 truck, this is the easiest way to get to 500. A tune alone can get you close, and a small turbo upgrade will make it clean and responsive. You can keep the stock injectors and CP3 pump. We do cover what to upgrade if you plan to tow at that power level or run the truck hard.No matter what truck you have, we talk about key things like head gaskets, studs, valve springs, fuel systems, and building a transmission that can take the power. This is not about throwing parts at your truck. It is about doing it right so it stays together and works for what you use it for.If you want a reliable 500 horsepower build that can still pull trailers and get you home every time, this episode is for you.

• The Stories Behind Our Favorite Diesel Builds

  In this episode of the Power Driven Podcast, we’re taking it back to our roots and talking about some of the most memorable trucks we’ve ever built. These aren’t just polished showpieces—they’re real-deal builds that have seen the street, the strip, and everything in between. Todd kicks things off with Ruby, his 2006 mega cab tow rig that started as a learning truck for common rail tuning and turned into a 1500 horsepower beast that can still hook up to a trailer. We also dive into the story of the Junker Drag Truck, a $1700 Craigslist find that turned into a legend after years of weekend wrenching and figuring things out the hard way. Then there’s the Shorty, a chopped 12-valve that’s now riding on a Duramax frame, four-wheel-drive, slammed low, and still making big power with compound turbos and a 6.7 Cummins common rail under the hood. Throughout the episode we talk about what worked, what didn’t, and what we learned from blowing head gaskets, snapping shafts, breaking blocks, and learning through it all. These builds weren’t done overnight, and none of them came easy. But every mile, every busted knuckle, and every late night in the shop was worth it. If you’re building your own truck, working with what you’ve got, or just looking for some real stories from guys who live and breathe diesel, this one’s for you.

• How Much Horsepower Do You Actually Need?

  Welcome back to the Power Driven Podcast. In this episode, we’re diving into a question that comes up almost daily — how much horsepower do you actually need? With social media hyping 1000+ horsepower street trucks like it’s the standard, it’s easy to get caught chasing big numbers before really thinking about what you want your truck to do. That’s why we brought in Griff, our head salesman at Power Driven Diesel, to talk through what he hears from customers and help break down the real-world difference between building a fun, usable truck and building something that ends up spending more time in the shop than on the road. Todd, Will, and Myer join the conversation, sharing their own stories from years of building everything from 500HP tow pigs to 1500+HP dyno monsters.This episode covers it all — why 600 horsepower might actually be the most enjoyable setup for daily driving and towing, what tradeoffs come with making four-digit power, and how your truck’s platform and goals should shape your build. We get into turbo sizing, engine clearances, cam choice, and how to avoid common mistakes like overbuilding an engine for a truck that’s never going to use that power. From sketchy street passes and blown-up builds to the sweet spot where power, drivability, and reliability all come together, this is the kind of honest, unfiltered conversation you can only get from guys who’ve lived it.Whether you’re just getting started with your first diesel build or looking to fine-tune a truck that’s already making power, this episode is full of real advice that can save you time, money, and a whole lot of headaches. So how much horsepower do you need? That’s up to you — but we’re here to help you figure it out and enjoy the ride along the way. Let us know your power goals in the comments, and don’t forget to like, subscribe, and call us if you need help dialing in your build.

• Cylinder Heads: The Key to Horsepower

  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.
