Listen to our story, as told by one of our founders, on The Truck Show Podcast (14 min to 60 min).
S&S Diesel Motorsport uses custom injector testing equipment, modified in-house, to thoroughly validate every product to a level of standards that exceed OEM capabilities. Measuring injection rate shape of complete sets simultaneously, and measuring the complete profile of five injection events per simulated combustion cycle are a few of the capabilities of the S&S fuel lab.
S&S Diesel Motorsport is capable of testing all sizes and models of high-pressure fuel pumps to varying speeds and outputs. Our modified test bench is capable of spinning a 1,850 mm³/rev CP3 pump in excess of 6,200 RPM to test durability in a high-rpm racing environment.
