Can Common-Rail Hang At The Top?
Last week, common-rail performance invaded PullTown USA, a Duramax won the ring at the National Tractor Pulling Championships, and huge dyno numbers were made from coast to coast.
According to O’Bryant Diesel Service and S&S Diesel Motorsport common-rail technology can hold its own—and this weekend’s performance at PullTown USA proves it. Friday night at the National Tractor Pulling Championships in Bowling Green, Ohio, Patrick O’Bryant’s latest creation made its debut in the Super Stock Diesel Truck class. Out of 34 4,000hp-caliber trucks, it finished third with a 321.965-foot hook. “Outa Time” would turn in an Eighth Place distance on Saturday and end up fourth overall at the prestigious 2-hook affair. Partnering with S&S, O’Bryant threw the kitchen sink at the tube chassis, third-gen. Three Ordnance 560 CP3’s provide rail pressure, S&S’s new double barrel fuel rail stores the pressurized diesel, and “very large” Ordnance injectors quickly distribute fuel in-cylinder. A MoTeC stand-alone ECU running S&S’s custom firmware controls the billet Cummins, while a big single turbo feeds it boost.
Winning The Ring
Another pleasantly surprising performance in PullTown USA stemmed from the “Totally Outta Control” Duramax driven by Kevin Armstrong. His 6-inch single turbo’d V-8 proved the most consistent Super Stock horse in the race at Bowling Green, beating out the likes of Scheid Diesel’s Kent Crowder, Jon Woskob’s “Rollin’ Coal” Cummins, the aforementioned “Outa Time” common-rail, and a hard-charging “Cummins Killer II.” Kevin and his late-model GMC finished Fourth Place on Friday and took second on Saturday, securing the coveted ring that can only be earned at the National Tractor Pulling Championships. Make your plans now to attend next year, as it will be the 60th running of the time-honored, late-summer truck and tractor pull.
3,551 HP On Fuel
Speaking of common-rails capable of making big horsepower, Dynomite Diesel Products‘ Lenny Reed has been busy pushing the limits of his Perkins Diesel-built Cummins in the middle of Missouri. When Zack Hamilton dares you to split his CGI block and Hart’s challenges you to join the big boy club, you shoot for a colossal number on the engine dyno. Last week, the Baldur’s-controlled bullet destined to power DDP’s “Patriot” Super Stock puller produced a fuel-only 3,551 hp (and tapped 6,000 rpm). Incredible numbers from a common-rail—and one breathing through a single turbo. Who’s ready to see DDP’s cut-tire monstrosity take a bite out of the dirt?!
On The Chassis Dyno
Daily Driven Performance Brings Heavy Hitters To Southeast Idaho
The Daily Driven Performance & Idaho Diesel Adventures Dyno Day went down over the weekend, and boy did it attract some heavy hitters. First and foremost, the event saw the first female to ever reach the 2,000hp milestone. After her ’06 Mega Cab produced a solid, 1,515-rwhp on fuel, Boosted Distributing’s Rachael Hicks turned on the bottle, hopped back in line, and blew past the 2K mark with a 2,387hp effort aboard the Northwest Dyno Series SuperFlow. And although the run unfortunately windowed the block, Rachael already has plans in the works for a bigger and badder rebuild. The highest number on the day would belong to Randy’s Transmissions’ Red Delicious. After clearing 3,605 hp, the guys at Randy’s returned for an encore performance of 3,763 hp. Insane.
A 7-second VP44 Cummins Hits The Rollers
Earns a double-class win up against some of the toughest ODSS racers in the business one week, then lays 841 hp down on the dyno a few weeks later… Meet Jordan Blackard’s “Everyday Diesel”, an ‘01 second-gen Cummins with a 24-valve 5.9L engine still rocking the VP44. According to the rollers, Jordan’s compound turbo’d (GT Performance charger equipped) Ram is good for 700-rwhp on fuel—and an impressive 841-rwhp on a single shot of nitrous (via .136 jet). Riding high off his recent 7.70 Index and ET Bracket class wins at the Bluegrass Truck Jam, you can bet Jordan will be looking to the carry the same winning momentum into this weekend’s race at the Scheid Diesel Extravaganza.

Building The Ultimate Street-Driven 7.3L
With companies like Jelibuilt Performance keeping 7.3L Power Stroke performance alive, the following for these Navistar-built, HEUI-fired V-8s may never die out. The company’s latest project, a bone-stock early ’99 F-250, is currently tasked with being the test-mule for some E99 tuning. Once that’s done, a built Kill Devil Diesel engine is getting swapped into place and Jelibuilt will be gunning for 1,000 hp. The recipe? Think 350/200 hybrid injectors, a competition fuel supply system, a T4 turbo arrangement, and a built 4R100. When exactly things go from 0-to-100 mph we don’t yet know, but when we do we’ll be sure to provide an update.
