What happens when a truck you built for testing accidentally becomes the perfect race weapon? That's exactly what we're dealing with heading into the NHRDA Diesel Desert Nationals in Chandler, Arizona, and we are fired up about it.

In this episode of the Power Driven Podcast, we're breaking down everything you need to know about the brand new Blue Collar Class, a street truck drag racing format that is turning heads in the diesel performance world. No boost launches. No prepped surfaces. No Christmas tree countdown. They line you up, flip on a flashlight, and when it goes green, you go. That's it. It's the closest thing to a real stoplight race you'll find at a sanctioned event, and we are here for every second of it.

The class has strict turbo size limits based on your platform, a 7,000 pound minimum weight requirement, and a 400 tread wear tire rule so you can't just show up on a full race setup and blow the doors off everybody. They want real trucks driven by real guys, and with a $300 entry fee and a $20,000 payout purse on the line, the competition is going to be serious.

Here's the wild part. Our 12 valve test rig Vin-D, the truck we've been running injector tests, tow tests, and dyno pulls on for months, just so happens to sit right around 740 horsepower with a 67.9mm turbo and a towing cam. We did not build this truck for the class. It just worked out that way. Now we're going to dial in the wastegate, throw on some fresh rubber, and see what this thing can do when the light goes green from a dead idle.

We also talk about which platforms have the real advantage in a class like this, why common rails could be tough to tame off the line, and what it would take to actually build the perfect Blue Collar Class truck from scratch. If you've ever wanted to go racing without dropping a fortune on a purpose built drag truck, this episode is going to get your gears turning.

Ever dropped a stack of cash on a diesel performance mod and wondered why your truck drives worse than before? Yeah, we've been there. In this episode of the Power Driven Podcast, Todd, Myer, and Will sit down in the race shop to talk about the modifications that people do to their diesel trucks that either flat-out ruin them or just don't deliver what they promised.

We kick things off with the age-old debate about leveling kits, stance boy wheels, and oversized tires on diesel trucks. Will's got some strong opinions here, and if you've ever wondered why your second gen Dodge or third gen Cummins follows every groove in the asphalt like a shopping cart with a bad wheel, this is the conversation you didn't know you needed. Spoiler: your ball joints aren't happy either.

From there we get into the performance mods that sound great on paper but end up costing you more than they're worth. We're talking oversized injectors, 13mm injection pump sizing on builds that have no business running them, and the classic mistake of throwing the biggest, baddest parts at a tow truck that just needs something sensible. We hear from guys constantly whose 12 valve Cummins or VP44 went from awesome to terrible overnight chasing a spec sheet.

We also dig into the intake horn debate with real dyno testing data, cold air intakes, intercooler upgrades, diesel exhaust systems, and the old school practice of dropping compression with oversized head gaskets. All covered with actual shop floor experience, not just YouTube theory.

The big theme of this episode? Right-sizing your build for your actual goals. Whether you're towing, pulling, or just want a badass street diesel, matching your parts to your power level makes or breaks the whole thing.

If you've ever had buyer's remorse on a diesel truck build or you want to avoid it, this one's for you.

Everybody loves boost. The higher that gauge climbs, the better, right? Well, not exactly.

This week on the Power Driven Podcast, Will and the guys get into one of the most argued topics in diesel performance. Boost. What it actually means, why more of it doesn't always equal more power, and where the whole "boost is just a measurement of restriction" idea even came from.

The conversation started after a buddy rolled in from Washington with a 6.0 Power Stroke on one of their new 68mm GT turbos. The thing laid down 662 horsepower to the wheels on completely stock heads and a stock intake. At only 33 pounds of boost. Meanwhile builds running 45 to 50 pounds are struggling to match that number. So what gives?

Turns out the number on your boost gauge is only part of the story. What's happening on the exhaust side, how well your cylinder heads flow, your intercooler efficiency, air density, exhaust back pressure, all of it plays into how much power actually makes it to the tire. The guys break all of that down in a way that actually makes sense whether you're building a diesel drag truck, a tow rig, or just trying to get more out of your daily driver.

They also get into why diesel turbo technology has quietly lapped the gas performance world, the real reason gasoline engines can make insane power at lower boost, and the tuning strategy behind the Junker's 1,170 horsepower 12 valve build.

Plus the age old turbo sizing debate, why chasing peak dyno numbers can actually ruin a truck, and why the best feeling diesel you've ever driven probably wasn't the highest horsepower one.

You don't feel a horsepower number. You feel fun.
