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? Hit that subscribe and fire off your questions in the comments.
