If you've been to a major national diesel event over the past half dozen years, chances are you've seen Robert Pearce doing his thing, working his magic on the Diesel Doctor dyno. His portable chassis dyno services were called upon throughout the country, including the Scheid Diesel Extravaganza and King of the Street, to name a few. Tragically, Robert passed away on January 19, 2022, shocking the diesel world with his departure. Diesel truck pulls, drag races, and especially dyno competitions will never be the same for the folks that strapped their vehicles to his rollers. Rest in peace, Mr. Pearce. The diesel community will always remember you.
