Raising The Bar (Again): Justin Goode Resets The 4×4 1/8-Mile Duramax Record

Back in February, Justin Goode established a new 1/8-mile ET record for a 4×4 Duramax when his LML-powered Silverado went 4.63 at 163 mph on radials. Over the weekend, Justin bested that on slicks, going 4.60 at 168 mph. It happened at the ODSS Smoky Mountain Throwdown, and on the heels of a pair of 4.70s in testing and a 4.65 in the second round of qualifying. But on top of establishing the new record, Justin and his crew worked feverishly to replace a blown up-pipe bellow and swap turbos in the pits in order to make the Super Diesel class final. As Justin’s team continues to eliminate chassis issues, look for his bad-to-the-bone Chevy to keep inching deeper into the 4’s.

At The ‘Strip

ODSS Season Finale In Knoxville

Thanks to Epling Motorsports, the Outlaw Diesel Super Series came to Tennessee’s Knoxville Dragway for the first time over the weekend. And what better way to host your first ODSS racing than by having it be the final event of the season? In come-from-behind fashion (and with a new personal best, 4.35-second pass on the weekend), Nathannial DeLong drove the Rudy’s Performance Parts Mustang to a win in Super Diesel, edging out a determined Justin Goode. In Pro Truck, Justin Zeigler took the win and sewed up the title. In 5.90 Index, Jordan Newman’s immaculate common-rail first-gen got the W while an uncatchable Brett Marcum celebrated the points championship (as well as a victory in the new, Firepunk-created Single NX class).

More ODSS Action From Knoxville

In 6.70 Index, Brandon Shank and his Duramax came out of nowhere to grab the win in his first ever ODSS appearance (pictured), and Cody Gilbert held on to the 6.70 season points lead to be crowned this year’s champion. As for 7.70 Index, Ryan Daniels would best Darrien Nickerson in the final, while Emanuel Yoder celebrated another championship in the class. When all was said and done in ET Bracket, veteran Robin Ridgway parked her 7.3L Super Duty in the winner’s circle while Dustin Canter celebrated earning the championship (as well as finishing fourth in points in 7.70 Index). In Top Diesel, Brianna Gilbert brought home another win (and S&S belt), but also held off Jordan Newman in 5.90 Index points for Third Place overall in 2026. Last but not least, ODSS 5.90 regular, Cody Helms, won the newly-created Firepunk Heavy Hitters class and took home a cool, $5,000 in cash.

On The Dyno

1,775 HP 6.7L Ford

According to KC Turbos’ Charlie Fish it’s one horsepower short of freedom, but to everyone else it’s about as impressive as it gets for a 6.7L Power Stroke. With race season winding down for the year, go-for-broke fever has commenced at the company’s Mesa, Arizona headquarters. A few days ago, their 6.7L-swapped (6.0L body) Super Duty coined “Lucky” was strapped to the rollers and had everything but the kitchen sink thrown at it. The short bed Ford responded by laying down 1,775 hp and 2,157 lb-ft—and it did it with just 850 microseconds worth of duration being commanded from the Kill Devil Diesel engine’s S&S Ordnance injectors. Rumor has it Charlie and company are headed to the track next—potentially to challenge the 1/8-mile record for a 4×4 6.7L Ford…

The Late-Model 1,075 HP Daily Driver

Joshua and Justin Hill of Hills Diesel have been playing with the 6.7L Power Stroke platform, too, and their spicy late-model Ford just made 1,075 hp and 1,601 lb-ft on the hub dyno at Ronin Brothers Performance. What’s more is that this may only be the tip of the iceberg. With friend Rhett Sprouse on the keyboard, a slight bump in timing and just 1,000 microseconds of injector duration were all that was needed to get the truck into four-digit horsepower territory. A set of 200-percent over injectors made it possible, as did the 12mm CP3 that was along for the ride. Joshua credits the advice, guidance, parts, and expertise provided by Snyder Performance Engineering for getting the truck to this point.

Competition Injector Tech With Exergy

500-Percent Over Nozzles Vs. Stock

Ever wonder what all those race application injector nozzles you hear about look like compared to stock? Exergy Performance has no problem providing an eye-opening visual. Here, a factory Cummins injector nozzle is juxtaposed with one of its 500-percent over competition units. Other than the obvious size difference in orifices between the two, notice that the OEM nozzle features a dual plane spray pattern while the competition version doesn’t. When Exergy builds a set of high-end injectors, things like spray pattern, spray angle, and even hole count is often altered to match the customer’s needs. An added bonus is that with a larger hole nozzle, less injector duration (pulse width, or injector on-time) is required to meet horsepower demands—which is much safer for the engine.
