Thanks to its innovative, industry-renowned products and services, S&S was chosen to play pivotal roles in what may soon become the first 3-second, diesel-powered machines in the world.

It also delves into the electronics side, including engine control units, power distribution modules, relays, and complete wiring installations. ![]() Today, the company specializes in common rail, electronically-controlled, high-pressure fuel systems for modern diesel engines - fuel pumps, injectors, and relief valves for everything from 50-state-legal street vehicles to 3,000-plus-horsepower, competition-specific applications. Langellier formerly specialized in engine development and performance calibration at Cummins, while business partner Andrew Stauffer was an engineer working on fuel systems at Bosch the two combined their skills into a potent combination at S&S. “There have been diesel engines for decades, but previous generations all had mechanical fuel systems - in the early 2000s the OE’s were met with further emissions requirements and reduced noise, and that drove the technology to these electronic fuel injection systems,” explained S&S co-owner Luke Langellier. The result are efficient, clean-burning, and quiet race engines capable of producing the kind of horsepower to run with their gas and methanol-fueled competitors. But diesel performance has come a long way, thanks in part to the efforts of companies like S&S Diesel Motorsport, who have driven technological leaps in fuel systems and engine management systems. ![]() Your father’s diesel engines were known for being dirty and loud, and while unrivaled in longevity and efficiency - at least relative to their spark plug-equipped counterparts at the extreme end of the spectrum - they weren’t exactly all-out performers in the racing world. ![]()
