8 years of power: FuelTech USA's Mainline ProHub 5000 dyno retires

In the world of automotive performance, tools become more than just equipment; they become trusted companions. For FuelTech USA, the Mainline ProHub 5000 dyno was just that—a reliable partner that witnessed the birth of some of the most powerful cars on the planet. After eight years of service and over 5,000 pulls, it’s time to say goodbye.

The team at FuelTech USA recently shared a heartfelt farewell to their outgoing dyno via a YouTube video. The Mainline ProHub 5000 has been a cornerstone of their shop, testing everything from Formula Drift builds to a V12 Ferrari with nitrous and a turbo. Its retirement marks the end of an era, paving the way for the more robust Mainline ProHub 6000.

The Legacy of the Mainline ProHub 5000

The Mainline ProHub 5000 dyno wasn’t just a piece of equipment; it was a testament to endurance and performance. Over its eight-year lifespan, it tested more than 5,000 vehicles, including four cars that exceeded the 5,000 horsepower mark. One of its most notable achievements was the world record run by Szabolics Marchese’s twin-turbo Pro Mod Camaro, which hit an astonishing 5,395 hp.

FuelTech’s Chief Operating Officer, Luis de Leon, shared stories about the dyno’s journey, recounting tales of insane four-cylinders, performance gurus from Brazil, and even a 1930s truck with a boosted overhead-valve inline-six. The dyno’s ability to handle such a diverse range of vehicles is a testament to its versatility and robustness.

Memorable Moments and Lessons Learned

The Mainline ProHub 5000 dyno wasn’t just about the numbers; it was about the stories and lessons learned along the way. One such lesson was the importance of securing the dyno to the floor, a measure that became necessary after some particularly powerful pulls. The dyno’s ability to withstand such forces is a testament to its engineering and design.

Among the memorable moments was the testing of a triple-turbo pulling tractor that surpassed 6,000 hp. While this didn’t officially break the world record set by Marchese’s Camaro, it showcased the dyno’s capability to handle extreme power levels. The Mainline ProHub 5000’s ability to adapt to such diverse and powerful vehicles is a testament to its engineering excellence.

The Future with the Mainline ProHub 6000

As cars continue to get more powerful, the need for more robust testing equipment becomes evident. The Mainline ProHub 6000 is set to take over where the ProHub 5000 left off, offering enhanced capabilities and reliability. While the ProHub 5000 will be missed, its legacy will live on in the records it helped set and the stories it helped create.

The transition to the Mainline ProHub 6000 marks a new chapter in FuelTech USA’s journey. The new dyno is expected to handle even more powerful vehicles, continuing the shop’s tradition of pushing the boundaries of automotive performance. As the team looks to the future, they do so with a sense of pride and accomplishment, knowing that the Mainline ProHub 5000 served them exceptionally well.

In the end, the retirement of the Mainline ProHub 5000 is bittersweet. It’s a reminder of the good old days and the incredible vehicles that passed through FuelTech USA’s shop. As the team moves forward with the Mainline ProHub 6000, they carry with them the lessons and memories of their trusted companion, the Mainline ProHub 5000.
