Welcome back to the Power Driven Diesel podcast. We’ve had quite a few people ask for more Common Rail content, so we figured it was time to dive in. In this episode, Meyer joins us to walk through a bunch of topics that matter if you’re running a Common Rail Cummins or thinking about building one. We get into tuning strategies, CP3 fuel systems, turbo behavior, and how it all works together when you start pushing power.

We kick things off with tuning basics. Meyer explains fuel timing and duration in a way that makes sense, especially if you’re new to this stuff. There’s a good breakdown of what it means when a truck is injecting fuel after top dead center and why emissions tuning often does that. We talk about how shortening duration and improving injection rate helps power, efficiency, and driveability. We also get into pedal maps and how your throttle input turns into actual fuel output. That part gets overlooked a lot, but it has a huge effect on how the truck feels behind the wheel.

From there we get into VGT turbo tuning. Will shares what happened when he upgraded the turbo on his wife’s Excursion and how the truck felt super lazy until he figured out the vane control. Just closing the vanes to make more boost actually slowed the truck down, and once he opened them back up, it ripped again. That’s a good lesson for anyone who thinks boost equals speed, because the truth is it’s all about balance and airflow.

We also talk about CP3 pump setups. For a long time, making big power meant running two or three pumps, but that has changed. Nowadays, a single 14mm pump or a dual CP3 setup can support big numbers, depending on what you’re doing. Meyer and Will both have experience running different setups and share what works better for street trucks versus all-out builds. The bottom line is, if you’re adding hard parts like injectors or turbos, you’ve got to retune or you’re going to leave a lot on the table.

Toward the end, we get into block design and why we’ve moved to using 6.7 blocks in most of our race engines. They have more material between the cylinders, stronger cooling, and we’ve seen them hold up better than older 5.9 blocks when pushed hard. That does not mean the 12-valve stuff is bad. It just means that newer options give you more room to grow, especially when you start mixing parts like 24-valve heads or building hybrids.

There is still a lot we did not get to, like transmissions and more platform-specific tuning, so if you have questions, let us know in the comments. We read those and we’re always down to do a follow-up. Thanks for listening, and we will see you in the next episode.

In this episode of the Power Driven Podcast, we’re taking it back to where it all started—our early days competing in the Ultimate Callout Challenge. If you’ve ever wondered what it takes to build a competitive UCC truck from the ground up, this episode is for you. We get into the gritty details of how we turned a mechanical 12-valve Cummins into a full-blown competition monster, and the chaos that came with trying to keep it alive through dyno runs, drag racing, and sled pulling.

We talk about the early struggles of building with limited resources, how we learned to dial in mechanical fueling on the edge of disaster, and what it was like pushing a triple turbo setup to its absolute limits. From camshaft failures to cobbled together fixes in the pits, we lay out everything we went through just to stay in the fight. You’ll hear how we went from unknowns with a budget build to a team that people started watching closely, especially when we dominated the sled pull with a setup no one expected to work.

This episode isn’t just a look back. It’s a deep dive into the mechanical mindset, the strategy behind each event, and the lessons we learned through trial and error. If you’re into real diesel performance, mechanical builds, or just love hearing what happens behind the scenes at big time diesel events, you’re going to want to listen to the whole thing.

We appreciate everyone who’s followed us since those early UCC days. This is the story of how Power Driven Diesel earned its place in the competition world through busted parts, long nights, and a lot of determination.

In this episode of the Power Driven Podcast, hosts Todd, Will, and Myer welcome special guest Damian, the man who went from enthusiast to event promoter with the launch of the first-ever Southwest Truck Fest. Recorded just weeks after the dust settled, we pull back the curtain on what it took to organize a diesel truck event from scratch, and what he’d do differently next time.

We break down the real-world challenges of launching a grassroots diesel event: securing city permits, dealing with insurance, managing vendors, and coordinating logistics like dyno scheduling, vendor placement, and traffic flow. Damian shares the three-month sprint from idea to execution and how Southwest Truck Fest attracted trucks and fans from across the U.S., including builds from Idaho, Texas, New Mexico, California, and even Washington.

We also talk horsepower, dyno numbers topping 2,400+ HP, what it takes to impress at a show-and-shine, and how event culture has changed in the post-COVID era. And yeah, we get real about the negative press, afterparty burnout fiascos, and what those viral moments mean for the future of diesel events in small towns like St. George.

If you’ve ever wondered what it takes to start a diesel truck show, or you just want to hear how the performance diesel scene is evolving, this episode is packed with insight, entertainment, and honest talk from guys who live and breathe this world. Whether you’re into dyno days, vendor row, burnout pits, or just rolling coal with your buddies, this is the podcast for you.

You’ve seen the SmokeStang light up burnouts on YouTube—now hear the backstory straight from Westen Champlin himself. We’re talking about how a $1500 junkyard 12-valve turned into a 1200+ horsepower weapon, what really goes down behind the scenes, and why building fast diesel rigs usually ends with something on fire (or broken).

From transmission failures and sketchy last-minute wiring to full-send dyno runs and burnout comps, this episode covers the kind of chaos that comes with chasing big power on tight timelines. Westen shares what it’s like growing a YouTube channel while juggling builds, towing rigs across the country, and trying to keep it all from blowing apart.

We get into the crossover between diesel drag racing, truck pulling, and burnout culture—and how U.S. events are finally catching up to the Aussies when it comes to putting on a real show.

We’re also talking about the upcoming Horsepower Rodeo going down May 24th in Winfield, Kansas—30+ pro-level builds, blown methanol setups, diesel trucks, and zero lift off the throttle.

If you’re into diesel performance, race builds, YouTube truck content, or just want to hear what happens when you stop caring about rules and start chasing horsepower, this one’s worth your time.

In this episode of the Power Driven Podcast, we dive deep into one of the most debated topics in diesel performance: why do diesels smoke? Whether you’re running a mechanical 12-valve or a high-pressure common rail, this episode unpacks the science, tuning strategies, and real-world variables behind black smoke, haze, and combustion efficiency.

We break down the fundamentals of air-fuel ratio (AFR), Lambda, and stoichiometric combustion in a way that makes sense for performance diesel applications. You’ll hear why even at a perfect Lambda of 1.0, diesels can still smoke, and how the fuel itself, injection timing, and in-cylinder mixing all play a role.

From the factory smoke limits and emissions standards to 1,200+ horsepower race setups, we compare how gasoline and diesel engines burn fuel differently, and why gas tuners often misinterpret smoke as bad tuning. Spoiler: diesel makes peak power around the same Lambda values as gas, but with very different combustion behavior.

We also dive into the role of swirl, piston bowl design, injector size, and pilot injection in controlling visible smoke and maximizing power. You’ll learn how boost, compression, and injection pressure change combustion characteristic, and why tuning a common rail is a completely different animal than dialing in a mechanical truck.

The conversation covers everything from sled pull smoke strategies to nitrous-assisted drag passes, and why some trucks need excess fuel to manage heat under extreme load. We even tackle the misconception that visible smoke is worse for the environment than clean-burning high-fuel-consumption setups, turns out what you can’t see may be doing more damage.

Whether you’re trying to keep your daily driver clean or pushing a race truck to its limits, this episode offers insight backed by dyno testing, Lambda data, and decades of hands-on diesel experience. We’ve spent years tuning around this exact issue, and this episode puts it all on the table.

In this episode of the Power Driven Podcast, we sit down with none other than Lenny Reed from Dynomite Diesel Products (DDP), one of the most respected names in diesel injector technology. This conversation dives deep into the evolution of diesel performance, from the early days of sled pulling with janky setups and burned clutches, to today’s cutting-edge common rail injector strategies, EDM precision, and the science behind why extrude honing might be killing your power.

Lenny shares raw stories about how he got started, the hard lessons learned from broken parts and bad advice, and how those failures led to the injector advancements we all rely on today. We talk about the horsepower arms race, how to make 1,200hp streetable, and why your injector spray angle might be silently sabotaging your build. The episode also covers the big-picture stuff, emissions regulations, the real reason trucks cost six figures, and how American manufacturing can (and must) evolve.

If you’re into tuning, dyno battles, injector flow rates, or just want to hear two OGs talk shop about what it really takes to go fast and not blow it all up, this is one you don’t want to miss. Whether you’re a daily driver diesel guy or a full-on competition builder, there’s something in here for you. Want more raw diesel talk?

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.

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.

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.

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.
