diesel invasion

Since the Jeep became popular decades ago, but more recently with the boom the JK and JL have created, Jeeps are everywhere you go and you’ll rarely be able to hit an off road trail anywhere in the country without seeing one. Several years ago a few friends of mine decided to rebel against this Jeep Invasion at one of the largest gatherings of off roaders each year, Easter Jeep Safari in Moab Utah. Being fans of Fullsize rigs they decided to call this rebellion “Fullsize Invasion.” Fullsize Invasion started as a small gathering of trucks and SUV’s hitting a trail or two and grew into a massive group hitting one or multiple trails per day during the EJS week. On these rides you’ll see anything from mainly stock tow…

OEM NEWS RAM IS BACK ON TOP! You didn’t expect Ford’s 2020 Super Duty to own the top towing and torque figures for long, did you? Finishing the year with a bang, Ram announced its 2021 model 3500 trucks will offer an available 37,100-pound gooseneck towing capacity—and that the new 6.7L Cummins will produce a best-in-class 1,075 lb-ft of torque. The additional 75 lb-ft of twist stems from a flow rate increase in the high-pressure common-rail injection system and a higher boost threshold for the Holst VGT. To support the Ram’s higher towing capacity, the rear frame rails have been fully boxed and the rear axle’s structural crossmember has been beefed up for 2021. Your move, Ford… SOURCE: MEDIA.FCANORTHAMERICA.COM OEM NEWS IT’S BACK… Across the pond, Volkswagen’s 2.0L TDI diesel is ready to comply with Euro…

the contender

Kenny Bruner’s ‘06 Dodge Ram is unquestionably over-the-top. From the bright paint and tilt front end to the big-horsepower engine and partial tube chassis, Kenny built his truck with one purpose in mind: to compete in the Ultimate Callout Challenge. “I really liked the idea of building a UCC truck,” says Kenny. “In addition to those types of events, I can still do dyno events, and when I can’t sled pull I can drag race. When I can’t drag race, I can pull. You can just use the vehicle for so many things,” Kenny continued. While he’s owned the truck for a few years, in 2019 things got serious, and the Ram went through a complete transformation. Kenny knew that in order to compete in the drag racing portion of UCC,…

common-rail injector tech

When high-pressure common-rail debuted on the LB7 Duramax back in 2001, it changed the way we look at diesels. Ultra-high injection pressure, solenoid-style, multiple-event injectors, and full electronic control over the system brought the most refined diesel performance we’d ever seen to the table—along with quieter, cleaner engine operation. When Cummins hopped on the common-rail bandwagon in 2003, the result was the quietest, cleanest-burning, and most powerful 5.9L it had ever produced. But once the aftermarket got ahold of electronically-controlled high-pressure common-rail, its true untapped potential was realized. Through ECM tuning alone, another 200-250 hp could be added to a truck’s bottom line, thanks in large part to the factory injectors and high-pressure fuel pump being capable of supporting it. Then it was time to find out what a modified…

strategic cooling

Exhaust gas temperature is the single most vital parameter to monitor on any diesel. Whether your truck has been highly modified, treated to moderate power upgrades, or is completely stock, you always want to keep EGT as manageable as possible. When the owner of this ’07 Chevrolet Silverado 2500 HD—a truck equipped with an S300 turbo system, a built Allison 1000, and EFI Live tuning—saw 1,300 degrees F on the pyrometer while towing, he wanted to cool things off sooner rather than later. His urgency to shed EGT was amplified by the fact that the engine under the hood was an LBZ, the Duramax that’s (arguably) the most prone to cracking a piston due to added power and excessive heat. The path to shedding EGT began with a thorough cleaning of…

the workhorse in question

When it comes to ’17 model year trucks like this one, it’s believed Ford began installing the larger, stronger connecting rods starting with Job 2 trucks. In our quest to find out if we have the “better” rods, we ran the truck’s VIN and build date by our contact at Ford, and were told our engine was in fact a Job 2. To find out for sure, we’ll be taking a peek inside the engine next time, as the compound turbo system requires the oil pan be pulled. That’s right, we said compounds. In the second installment, we’ll be adding the highest quality turbo kit in the industry and replacing the valley charger with the hottest selling VGT on the market. Make sure you’re here for Part 2!
