Our Capabilities
Custom Multi-Injector Station
Precision Injector Testing
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.
