Turbo Technology: Using Data and Precision to Push the Limits of Boost
In this high-octane edition of EPARTRADE’s Race Industry Now technical webinar series, Johnny Gilbert, Owner of Stainless Diesel, took center stage to share his deep expertise in turbocharging and data-driven performance. Hosted by Brad Gillie from SiriusXM, Ch. 90, the session delivered valuable insights for racers and builders looking to harness cutting-edge turbo technology to achieve peak performance.
Data-Driven Boost: Precision Over Guesswork
Gilbert emphasized the evolution from traditional seat-of-the-pants tuning to a precise, data-first approach. By leveraging sensors, engine management systems, and real-time telemetry, Stainless Diesel designs and calibrates turbo systems that respond exactly to the demands of high-performance engines—eliminating guesswork and maximizing every PSI of boost.
“What used to be art is now more and more becoming science,” Gilbert noted, illustrating how advanced datalogging tools enable tuners to detect inefficiencies, pinpoint flow issues, and fine-tune boost curves to perfection.
Custom Turbo Solutions for the Track
Stainless Diesel doesn’t just build turbos—they engineer full systems tailored to application-specific requirements, whether it's drag racing, pulling trucks, or diesel-powered land speed records. The webinar showcased several case studies, revealing how thoughtful sizing, housing selection, and wastegate strategies help meet horsepower targets without sacrificing reliability.
From compound turbo setups to V-band advantages, the discussion highlighted how Stainless Diesel maintains an edge by focusing on both performance and packaging.
Pushing the Limits Without Breaking the Engine
Gilbert also dove into the importance of managing exhaust gas temperatures, shaft speeds, and backpressure ratios, especially when pushing past conventional power limits. With the help of high-quality materials and precision machining, their team ensures that customers can boost harder and longer—with confidence.
“The key isn’t just making big power—it’s making it safe, repeatable, and data-verifiable,” said Gilbert.
Audience Q&A: Turbo Trends and Advice
The webinar wrapped with an interactive Q&A, where Johnny fielded questions on intercooler sizing, turbo lag reduction strategies, and diesel vs. gas turbo characteristics. He also gave practical advice for racers stepping up to their first custom turbo setup, emphasizing the need for clear goals, good data acquisition, and quality components.
