THE TRIALS OF JESSE WARREN

ONE MAN’S CARNAGE, TRIUMPH, AND OTHER-WORLDLY ADVANCEMENTS WITH THE 6.0L POWER STROKE

ONE MAN’S CARNAGE, TRIUMPH, AND OTHER-WORLDLY ADVANCEMENTS WITH THE 6.0L POWER

When you can make one of the most hated engines in the diesel world a contender on the biggest stage, it does more than simply stir the pot. It scares the hell out of the competition. Perhaps Jesse Warren thrives on that type of motivation. Or, perhaps he’s just a fan of the underdog in any scenario. But perhaps it’s the simple fact that he loves the 6.0L Power Stroke. We think it’s a combination of each of those. After all, rather than convert his engine of choice to mechanical or common-rail injection, or move on to a different platform altogether, he’s stuck it out with the HEUI system—even in an era where common-rail has taken over at the drag strip and on the dyno. Over the course of the past decade, Warren has taken oil actuated fueling to new heights—heights that up until a few years ago would’ve been thought impossible to reach.

But the road to get here hasn’t been without its obstacles, and Warren has experienced more than his fair share of carnage along the way. Everyone knows you don’t push a 6.0L Power Stroke to a

Fifth Place finish at the Ultimate Callout Challenge or campaign a 6.0L in the Super Stock pulling class by luck or chance. Long hours, endless dyno and flow testing, a whole lot of trial and error, and perpetually competing on the ragged edge have been par for the course throughout Warren’s rise to the top of the 6.0L game. In the following pages, we’re highlighting the high marks of what is perhaps the greatest underdog story in all of diesel. From a small-time, one-man operation working out of his garage to opening the doors at Warren Diesel Injection in 2010 to the 16-man army he currently employs, his journey has been a very successful one.

Today, Jesse Warren is best known as the avid drag racer, dyno king, and truck puller that owns Warren Diesel Injection in Guys Mills, Pennsylvania. Although his company is known for an array of 6.0L components at the present time, when he opened up shop in 2010 it was to build injectors. The first set of injectors Warren ever pieced together, and what kick-started everything, went into his own truck in the 2009 timeframe. They were 175cc units fitted with stock nozzles, and his company still offers them today. After that, Warren went a little bigger, experimented with larger nozzles, and a short time later started building injectors for customers.

Saying the engines Jesse Warren brings with him to compete at U.C.C. are extreme is an understatement. Beneath the factory-based, bright blue intake manifold and behind the massive set of front-mounted compound turbos on his U.C.C. 2017 setup, sat arguably one of the most exotic 6.0L Power Strokes ever assembled. A filled and O-ringed block, Wagler billet rods, 13:1 forged Mahle pistons, O-ringed and Cnc-ported heads, ARP Custom Age 625+ head studs torqued to 300 ft-lbs, and a valvetrain made up of a custom-grind, high-lift camshaft from Colt, solid lifters, and forged-steel adjustable rockers from Jesel sum up the hardparts used.
