FuelTech USA’s Mainline ProHub 5000 dyno, which operated for eight years and performed over 5,000 high-performance tests, is now being retired after a career that included four vehicles exceeding 5,000 horsepower. This machine served as the foundation of the shop’s testing operations, and its departure signals the end of an important chapter for a device that exceeded its expected lifespan.
The company’s farewell video, posted on YouTube, combines technical details with emotional reflection. More than just a piece of equipment, the dyno became a platform for record-breaking achievements, including Szabolics Marchese’s twin-turbo Pro Mod Camaro, which produced 5,395 hp—a mark that remains unmatched. Though a later triple-turbo tractor surpassed 6,000 horsepower, the ProHub 5000’s contributions remain central to its reputation.
Its versatility extended beyond extreme horsepower figures. The dyno tested Formula Drift vehicles, a nitrous-enhanced V12 Ferrari, and even a 1930s truck fitted with a modified inline-six engine. Enthusiasts from Brazil and other regions traveled specifically to use it, and its reliability became legendary after surviving a near-tip during a high-output run, prompting the team to permanently anchor it to the floor.
Luis de Leon, FuelTech’s Chief Operating Officer, dedicated nearly an hour of the video to sharing personal anecdotes about the machine. Its role went beyond mechanical testing—it witnessed the evolution of tuning culture, from street cars to race-ready builds, without ever failing. The dyno’s durability matched its importance.

Modern vehicles now require greater torque and power outputs than the ProHub 5000 could safely accommodate. While the new ProHub 6000 model will handle these demands, the original’s impact transcends specifications. It was a key player in shaping performance advancements, and its retirement is both a practical necessity and a cultural milestone.
The farewell video avoids corporate jargon, focusing instead on memories. A dyno that endured eight years of continuous use, supported 5,000 test sessions, and enabled cars to push boundaries is being replaced, yet its influence persists. The successor will perform better, but the original earned its place in history.
For the shop, this transition is a logical upgrade. For those who relied on it daily, the ProHub 5000 was more than machinery, it was a partner in development. The dyno didn’t just measure performance; it helped define it.
FuelTech’s Chief Operating Officer emphasized that the ProHub 5000’s retirement isn’t just about technical limits. It represents the passage of an era in which tuning culture thrived, and its legacy lives on in the vehicles it helped create. The new model will carry forward the work, but the old one’s contributions remain unforgotten.
