Power Driven Podcast

2800 degrees does matter. That will melt everything after the engine.” We kick this one off with a real story about a pegged EGT gauge and use it to crack open what exhaust gas temperature actually tells you and why placement matters. We explain EGT in plain terms and dig into the difference between reading pre turbo and post turbo, including the ballpark rule one of us saw when testing that showed roughly 100 degrees per 10 pounds of drive. Most light duty diesel folks read pre turbo, so the rest of the conversation stays there.

From there we poke at the old 1250 safe myth and talk about why newer common rail trucks can see 1350 to 1400 on a hard pull while a 12 valve might not love that long term. Timing plays a huge role and we lay out how advancing timing can drop the EGT number while raising the actual heat the piston sees. That’s why a lower number isn’t always safer. We walk through the failures we’ve actually seen in the shop and at the track like melted turbine wheels and dividers when the hot side is the weak link versus pistons that scuff from heat and clearance. We also share a simple towing habit that helps, which is watching coolant as a proxy for oil temperature and backing off after a big climb instead of idling hot.

If you’re fighting high EGT while towing we talk through fixes that work in the real world. The big one is getting the right turbo for your RPM and load because a mid sized single makes a truck smoky and hot. Freeing up the exhaust after the turbo helps drive pressure and spool. An upgraded intercooler can drop intake temps and we’ve seen that turn into a noticeable EGT reduction. Cylinder head flow and a sensible cam improve volumetric efficiency so the same fuel makes more power with less heat. We even get into water and water meth injection and where it can make sense. We wrap it with how we’d spend money on a tow build with tuning first then turbo then fuel and why that order worked on our own tow rig. If you care about towing, turbos, timing, common rail versus 12 valve behavior and real diesel performance, this episode is for you.

Fuel mileage is one of those things everybody talks about, but when you start digging into it, you realize it is not just one magic mod. In this episode of the Power Driven podcast, the guys get into what actually moves the needle on diesel pickup fuel economy and why some trucks can pull off numbers like 30 miles per gallon when most people assume that is impossible.

It kicks off with a FreedomWorks video where a built 12 valve Cummins shocks everybody by cracking over 30 mpg in a baseline run, and that launches the whole conversation. They talk about how that truck was not stock, it had things like timing bumped, bigger turbo setup, four inch exhaust, and it was a two wheel drive, which matters more than people want to admit. From there they get real about the biggest easy win, getting rid of waste, and a lot of that starts with how fast you are driving. Dropping speed to keep rpm down and cut wind drag can be the difference between a normal 16 to 17 mpg truck and something that starts creeping into the low 20s.

Then they spend serious time on tires because the difference is not small. They explain why skinny tall tires like a 235 85 16 can help drop cruising rpm and rolling resistance, and they compare that to what happens when you go bigger and more aggressive. They also get into the reality of injectors and timing, and why more timing is basically step one across platforms, whether you are talking 12 valve, 6.0 Power Stroke, or common rail. They break down timing in plain terms, why emissions pushes timing in a certain direction, and how tuning decisions like timing split can make a truck efficient without being risky when you are just cruising.

From there it rolls into airflow and turbo choices, why turbine side matters so much for efficiency, and how transmission lockup, rail pressure, and even smoke all tie back into fuel economy. The whole thing feels like a shop conversation that connects the dots between diesel performance parts and real world miles per gallon without pretending there is one simple answer.

Diesel drag racing is officially back, and 2026 is shaping up to be a turning point for the sport. With new ownership, renewed momentum, and real effort being put into growing diesel motorsports nationwide, this episode of the Power Jam Podcast breaks down why now is the time to get involved and how anyone with a diesel-powered vehicle can jump in without it being intimidating.

In this episode, the guys talk through what the changes in diesel racing actually mean for everyday enthusiasts, from the resurgence of organized events to the excitement around unified rules and growing participation. They reflect on how diesel drag racing exploded in the early 2000s, why it slowed down over the years, and why the conditions are finally right for it to grow again. The focus isn’t just on watching from the stands, but on encouraging more people to bring their trucks to the track and experience it firsthand.

A big portion of the conversation walks through exactly how to get started racing, especially in the Sportsman class. They explain why you don’t need a fast truck, a massive budget, or race-only equipment to participate, and how consistency and reaction time matter more than horsepower. From tech inspection and staging lanes to understanding the tree, reaction times, and time slips, the episode removes the mystery around drag racing and makes it approachable for first-time racers.

The discussion also covers how bracket racing works, how dial-ins and reaction times decide races, and why slower classes are often the most competitive and fun. As the episode progresses, they touch on moving up into faster classes, what changes as speed increases, and why learning the fundamentals in Sportsman sets you up for long-term success.

If you’ve ever thought about racing your diesel truck but didn’t know where to start, this episode lays it out in real-world terms. It’s about growing the sport, helping new racers feel welcome, and keeping diesel motorsports alive by getting more trucks on the track.

We learned some things in 2025 that completely reshaped how we think about diesel performance, and a lot of it challenged what most people assume about power, smoke, and tuning.

This episode of the Power Driven Podcast is a year end breakdown featuring the Power Driven Diesel crew reflecting on everything they tested, broke, and learned throughout the year. The conversation covers diesel performance across multiple platforms including 12 valve Cummins, common rail Cummins, and VP44 setups, along with what real dyno testing and track time revealed. From R&D and turbo testing to race truck builds and tow rigs, this episode explains why small details in air, fuel, and timing matter more than chasing parts alone.

One of the biggest topics is smoke versus power and why adding fuel does not always mean more performance. They dig into the question of whether smoke adds power on a diesel and explain how different platforms respond, especially comparing older 12 valve technology to modern common rail engines. The discussion naturally leads into AFR tuning, running lean versus rich, and how nitrous diesel tuning completely changes the equation when it comes to heat, burn efficiency, and timing. There’s a deep look at nitrous on diesel engines, including why pulling timing with nitrous is critical, how automated nitrous control improves consistency in diesel drag racing, and why feed line size and solenoid flow actually matter.

Turbo upgrades and truck builds are another major focus. The crew breaks down real dyno results from turbo testing on different trucks, including the Junker drag truck, Windy, and Willard. They talk through GT55 and Aggressor turbo results, injector sizing lessons, and how some setups made more power than expected without bending factory rods. There’s also insight into wastegate testing, comparing screamer gate versus hot pipe gate setups on compound turbos.

The episode wraps with lessons on VP44 Cummins performance, towing capability, camshaft upgrades, cylinder head flow testing, and why there’s still a lot of untapped potential in Cummins head design.

If you had to pick just three upgrades to make your tow truck better, what would they be?

In this episode of the Power Driven Podcast, Will, Todd, and Meyers break down their own personal tow trucks and go head to head choosing their top three favorite upgrades. They turn it into a white-elephant style game where once a mod is picked, nobody else can use it, forcing each guy to really think about what has made the biggest difference in how their trucks tow, drive, and survive long miles. This conversation hits home for diesel enthusiasts because it focuses on real world diesel performance, not bench racing or internet theory.

The episode kicks off with tuning as a must-have upgrade and why controlling fuel, power delivery, and transmission behavior is step one for any modern Cummins tow rig. They explain how multiple EFI Live tunes allow different transmission pressure strategies for towing versus street driving, and why constant high line pressure is a fast way to create unnecessary heat and wear. From there, turbo upgrades come into play, including variable geometry turbos with billet actuators and how a stronger, more consistent exhaust brake can completely change downhill control and driver confidence.

As the picks continue, the conversation moves into built transmissions with second gear lockup, lower stall torque converters, and why factory shift strategies fall apart once you add power. They also dig into suspension upgrades like airbags and onboard air systems, explaining how leveling the truck and controlling tongue weight makes towing safer and more predictable. Exhaust brakes, rear sway bars, headlights, brakes, shocks, and tires all come up as critical upgrades that reduce stress when towing heavy through wind, traffic, mountains, and backroads.

Over the course of the episode, the conversation naturally bounces between real world diesel performance, Cummins tow rigs, tuning strategies, turbo setups, and what actually makes a truck nicer to live with when you’re towing heavy. It’s the kind of discussion that comes from years of hauling trailers, breaking parts, fixing mistakes, and figuring out what upgrades actually make a difference.
