No Mercy 16 is fast-approaching and not only will Firepunk Diesel be there with its Plum Crazy Pro Mod, but they’ll also be looking to break their own diesel door-slammer record. Last year, the company’s 1970 Duster—a car powered by an Exergy-fueled, all-aluminum, Executioner series Cummins from D&J Precision Machine—ran a best of 3.85 at 198 mph through the eighth-mile. Driver Larson Miller would also grab a 60-foot record while he was in town: an incredible 0.975-second 60-foot. How much quicker will the fastest door car diesel in the world go this time? October 9-12 at South Georgia Motorsports Park we find out!

Bronco concepts have been hot topics for decades. This one was actually built, and a Ford Executive (who remains unnamed) loved it so much, they had their own built. The one in the photos belongs to Ford and is kept in their "Heritage Department" (man, we'd love to take a tour of that department). Powered by a V10, the concept started life as an extra cab Super Duty built sometime in 1998, so at the time, it was the most current Super Duty design. After some chopping, welding, bondo-ing, etc., the end result is what you see here. V10 powered... this thing has to be a blast to drive! Check out the video at the link below for more of this beast.

Check out this gem, Adam Shyrock of Kentucky Diesel Specialists was kind enough to share. The intake grid heater on this 6.7L Cummins was so chock full of soot buildup that it barely ran and could hardly accelerate anymore. Perhaps the worst news is that this is only a ’22 model year Ram. The cause? EGR, of course. But we’re willing to bet this fifth-gen has an obscene amount of idle time on the clock. Note that EGR is most active (in any diesel engine) at idle, when no load is present. If this Cummins has one thing going for it, it’s that a failed grid heater nut isn’t getting very far…

Since tuning of the ’24-’25 L5P Duramax’s E42 ECM became possible (thanks to HP Tuners), the usual suspects have been doing some very big things with the latest GM platform. One of those companies is DuramaxTuner.com. The guys there squeezed an additional 330+ lb-ft of torque out of their ’24 GMC Sierra AT4X HD dyno mule, along with seeing 100+ hp gains at the rear wheels. Taking advantage of what the latest L5P’s improved turbo, cylinder heads, and fuel system have to offer, the truck went from 444-rwhp and 974 lb-ft stock, to 555-rwhp and 1,310 lb-ft tuned. In summation, your new HD can be transformed into an emissions-intact hot-rod with one call to DuramaxTuner.

Of the 200-plus vehicles that hooked to the sled at the 2025 Scheid Diesel Extravaganza, Josh Land’s Limited Pro Stock Dodge was one of them. Only this time, he wasn’t competing in Limited Pro Stock. For SDX, Josh decided to throw cut tires and a 3.6-inch smooth bore turbo at the “Crippler” and see what it could do in Pro Stock. The common-rail Cummins-powered second-gen responded with an eighth-place hook on Friday night, and an impressive Second Place distance on night number 2. This past weekend, Josh joined the Mid-South Pullers Association for another Pro Stock event—and grabbed another Second-Place finish.

Who knew that 30-plus years after leaving the assembly line, folks like Hassler Diesel would still be addressing the killer dowel pin issue on 5.9L Cummins engines. Many of you know it well, the 8mm steel dowel pin Cummins employed on the assembly line to align the timing cover with the block, but also that can become a 10-cent wrecking ball if it ever works itself free from the crankcase. Some KDP’s make their way into the oil pan without incident. Others drop into the camshaft gear and cause all sorts of destruction. It’s a lot like Russian roulette. Still, tabbing (or staking) the KDP in place, or removing it altogether remains the best peace of mind any ’89-’02 5.9L owner can ask for.
