Three 6.0L’s Earn Spots On The Firepunk Top 10 (Dyno) List
Three 6.0L fire-breathers hit the dyno at Firepunk, O’Bryant Diesel’s common-rail Super Stock puller dominates in Kentucky, and another third-gen Cummins is bound for 4-second 1/8-miles.
6.0L’s like to party, too. Just take Gavin Ferguson and his friends for example. Over the weekend, Gavin, Steven Sawor, and Tyler Lambert made it onto the infamous chassis dyno “leader board” at Firepunk Diesel—a place where some of the most powerful competition and street trucks in the country go to be fine-tuned and make hero pulls on the rollers. Gavin’s show-quality Super Duty—a truck that benefits from a built engine, Warren Diesel 430cc/150-percent over injectors and billet twin HPOP system, and a SoCal Billet Inc. compound arrangement (a Bullseye S476/87/1.0 paired with a TDI 494/96 atmosphere charger) led the trio with 1,807 hp. Steven and Tyler followed suit, with impressive 1,542 hp and 1,512 hp efforts, respectively. As of today, Firepunk’s Top 10 dyno list includes a 6.0L in the number 4, 8, and 9 spots.
At The ‘Strip
Knocking On The Door Of 4’s

Michael Brown has been gearing up for the ODSS finale this weekend in Knoxville, and a weekend trip to Beech Bend Raceway Park nearly got him the 4-second 1/8-mile he’s been looking for. Following a new personal best on fuel (a 5.48), Michael turned the bottles on and laid down his quickest pass to date: a 5.05 at 147.97 mph. In a 5,100-pound truck, that trap speed suggests more than 2,300 hp is being applied down track. With a smoother launch and a quicker 60-foot, Michael’s Exergy and Flux fueled, D&J powered third-gen Cummins should have no problem breaking into the 4’s. Catch Michael and his truck in action this weekend at the ODSS Smoky Mountain Throwdown.

Locker, Limited Slip, Or Open Diff For Big HP 4×4 Diesels?

It was all going well for RedLine Transmission’s Karl Mireiter. His common-rail swapped ’95 Dodge—a Seventy 2 Fast candidate as well as a formidable 5.90 Index contender—was chipping away at low-6-second 1/8-mile ETs, on its way to the 5’s. Then it happened. Enough power was added that wheel spin entered the picture, along with hopping and a front-end shake he’d yet to experience in the truck. Karl took to social media, asking fellow racers what they run and what they think works best—and the answers surprised us. To many racers, an open diff is the only way to go, and it’s what former UCC and ODSS champion Justin Zeigler prefers. To others, a properly set up limited slip is highly advantageous, while most shy away from a full-on locker. Long story short, there is no general consensus on what works best—only that an open diff could be the safest bet at high horsepower.
In The Dirt
Leitchfield Fall Showdown

Central Kentucky was treated to back-to-back nights of truck and tractor pulling over the weekend courtesy of the Leitchfield Fall Showdown. In the Super Stock Diesel Truck class, O’Bryant Diesel Service’s S&S fueled (and MoTeC controlled) “Out Of Time” Cummins won both sessions with Adam White behind the wheel, once again proving this common-rail monstrosity is here to stay in the top ranks of diesel truck pulling. In the 3.0 Diesel Truck class, Chuck Dutter piloted “The Common Hooker” to the winner’s circle on Saturday while Dalen Bell’s first (Friday) and Third Place distances in the “Trailer Trendz” Dodge earned him the overall win for the weekend. In the 2.6 Diesel Truck category, Ryan Perkins put “In Harms Way” out front on Friday, with Austin McKenzie’s “The Agitator” taking the W Saturday night.
New To Market
Hot Shot’s New Anti “Glug,” Dual-Handle, Visible Level Oil Jug Design

A simple change, maybe, but one that its customers will appreciate at each and every service interval. Hot Shot’s Secret just redesigned its gallon jugs to incorporate both a top and side handle, making its containers easier to carry. In addition to the jug redesign comes an anti-glug feature—which makes the contents easier to accurately measure and pour. Finally, molded, liquid-level graduations on the bottle allow the user to clearly see how much product remains (and how to better gauge the amount being used). It’s another subtle reminder that when Hot Shot’s Secret isn’t revolutionizing the engine oil, additive, and fuel market with another ground-breaking product it’s pouring resources into its existing product line to improve the customer experience.
